Abstract:

Slider-crank mechanisms are used in many machines where there is a need to transform rotary motion into translation, and vice versa. Implementation of the control into a mechanical assembly of the slider-crank mechanism offers a wide range of applications of such controlled mechanism in mechatronic systems. This paper shows an example of the remote control of the angular velocity of the crank in a mechatronic redesigned slider-crank mechanism in order to achieve the desired motion of the slider. The remote control is achieved over the Internet connection and the appropriate software which is executed in the user’s internet browser. The aim of this paper is to present the applied control algorithm as well as to explain advantages of the possibility to remotely run a mechatronic redesigned slider-crank mechanism in service. This is done through an example of using a controlled slider-crank mechanism in a remote laboratory experiment.

Abstract:

The dynamical equation of the slider-crank mechanism is established by using Lagrange equation and Newton’s second law. The slider-crank mechanism with an open crack rod is investigated and then establishes the equivalent mechanics model by a massless torsional spring to simulate the influence of the crack in the rod, and the mechanism of a cracked rod is divided into two subsystems. The dynamical equation of the slider-crank mechanism with a crack rod is established. Comparing the dynamic analysis results between with and without crack in the rod, the results show that the existence of the crack leads to a great change in the motion characteristics of the slider. The calculated maximum Lyapunov exponent is positive, which shows that the movement of the slider in the crank slider mechanism with a cracked rod is chaotic.

Abstract:

The slider-crank mechanism is a special case of the four bar linkage which is widely used in reciprocating machines. Flexible multi-body mechanisms that gain some motion through the deflection of flexible elements are classified as compliant mechanisms. Dynamics of flexible slider-crank mechanisms is presented in this paper. Both rigid and flexible parts are included in the slider-crank mechanisms. As one of the widely accepted dynamic analytical method for the multi-body system modeling, floating frame reference formulation has been applied to derive dynamic formulations. Simulations of dynamics of flexible slider-crank mechanisms have been carried out using Matlab. It was shown that flexibility of parts has a certain extent effects on mechanical properties of flexible system that disagree with that of rigid ones.

Abstract:

In this paper, the problem of active damping of the elastodynamic vibrations of a flexible slider-crank mechanism is addressed. The slider-crank mechanism is such that the connecting rod is flexible and the crank link is rigid. The slider-crank mechanism system is underactuated since the connecting rod is not directly controlled. A dynamic model for the slider-crank mechanism is derived using the Hamiltonian principle. Then, a control scheme based on an energy approach is proposed. The control scheme uses the passivity of the system to eliminate the vibrations of the flexible connecting rod. Simulation results are given to illustrate the theoretical developments.

Abstract:

The crank-slider mechanism is the key component in reciprocating pumps. With the increase of the rotational speed of the crank-slider mechanism, the vibration and working noise of reciprocating pumps increase. Based on the multi-body dynamics theory, the dynamic model of the crank-slider mechanism of reciprocating pumps is proposed. A numerical example is given and the validity of the procedure developed here is demonstrated by analyzing the dynamic behavior of a typical crank-slider mechanism of the reciprocating pump. The model can well simulate the dynamic response of the mechanism, which can enable designers to obtain required information on the analysis and design of reciprocating pumps.

Abstract:

Complex mathematical problems have been solved with the aid of software application to obtain reliable results. The positional kinematic analysis of a slider crank mechanism involves computation of the motion parameters: linear displacement, velocity and acceleration of the slider; and angular velocity and angular acceleration of the connecting rod for every 300 variation of the crank angle. This study aimed to develop a customized software which can be used to efficiently analyse a given design of a four-bar and a slider-crank mechanisms. A program was written using VB (Visual Basic) programming language for the equations of angular velocities and angular acceleration of the coupler and follower for the four-bar linkage and the linear velocity and acceleration of the piston for the slider crank mechanism. The program was tested with different parameters for the mechanisms and the solutions compared with the results from manual calculations. The findings revealed that there were no differences (p ≤ 0.05) between the results using the program and manual calculations, which imply the accuracy of the program. It can be concluded that the program could be used to solve problems of four- bar linkage and slider-crank mechanisms.

Abstract:

Abstract. In this paper we consider the formulation and solution of the task of a dynamic synthesis machine with an asynchronous electric motor and a slider-crank mechanism. The constant parameters of the slider-crank mechanism (mass and moments of inertia and centers of gravity of links) and the parameters of the electrical motor are defined. The laws of motion of the machine and kinematic parameters of the mechanism are considered as given. We have developed the method of optimal dynamic synthesis of the machine, which consists of an asynchronous electric motor and a slider-crank mechanism. The criterion of optimization of the dynamic synthesis of a machine is the root mean square sum of the moments of driving forces, the forces of resistance and inertia forces which are reduced to the axis of rotation of the crank. The method of optimal dynamic synthesis of a machine can be used in the design of new and the improvement of known mechanisms and machines.

Abstract:

Abstract. When implementing the technological process on crank presses, it is necessary to provide a predetermined working cycle of the slider motion: fast lifting, dwell, and slow lowering. The cycle cannot be realized without controlling the motor. In addition, using controllable motors increases the manufacturing cost. Due to the geometric and kinematic capabilities of the mechanism, changing the kinematics of the working link is the best choice. Thanks to the use of the Stephenson II mechanism, the slider skew is eliminated due to the parallel connecting rods and the increased area of slider contact. This study presents a numerical method for kinematic synthesis of the Stephenson mechanism that has kinematic advantages. The method is based on mean square deviation which is the minimizing of an objective function. Thanks to the proposed synthesis method, approximate dwell movement can be performed when the slider is on the bottom dead center. In this study, values of the crank length and parallel connecting rods' lengths, angular coordinates of the crank and connecting rods, and the eccentricity of the guide slider relative to the crank rotation axis were obtained. It is observed that eccentricity affects the lower forward and higher backward speed of the slider. The kinematic results of the slider movement are comparatively presented in this article.

Abstract:

The current article presents the parametric equations for the synthesis of a slider crank mechanism with a coupler point passing through two specified acceleration poles that accord with two specified crank angles. The parametric equations for the coordinates of the acceleration pole for the coupler with respect to the frame are shown to be functions of only the geometric configuration of the slider crank mechanism driven by the crank with a constant rotational speed. Moreover, a necessary condition for the crank angular interval corresponding to the two acceleration poles on a coupler curve generated by a slider crank mechanism is investigated. The desired coupler point of a given mechanism passing through two acceleration poles should be a double point on the locus of the acceleration pole described on the coupler plane. The transformed parametric equations on the fixed plane are then applied to synthesize the desired mechanism with a coupler point passing through two specified acceleration poles that accord with two specified crank angles.

Abstract:

This paper mainly proposes an efficient modified particle swarm optimization (MPSO) method, to identify a slider-crank mechanism driven by a field-oriented PM synchronous motor. The parameters of many industrial machines are difficult to obtain if these machines cannot be taken apart. In system identification, we adopt the MPSO method to find parameters of the slider-crank mechanism. This new algorithm is added with “distance” term in the traditional PSO’s fitness function to avoid converging to a local optimum. Finally, the comparisons of numerical simulations and experimental results prove that the MPSO identification method for the slider-crank mechanism is feasible.

Abstract:

A three-degree-of-freedom Delta parallel manipulator driven by a crank-slider mechanism is proposed. In Cartesian space, a gate-shaped curve is taken as the path of the pick-and-place operation, combining with the inverse kinematics theory of the Delta robot, and a mathematical model of robot statia force transmission is established. The force and the output torque of the robot-driven joint are taken as the main performance indexes, and the value of the crank-slider mechanism applied to Delta robot is further measured. The simulation results show that the delta robot driven by the crank slider mechanism can reduce the force and output torque of the driving joint during the picking and discharging operation, and has good practical application value.

Full text

Abstract:

This paper investigates the possibility to individually balance the specific shaking forces and shaking moment of the slider-crank mechanism. The most common mean of balancing the slider crank mechanism is to use a counter mass. This solution is applied for almost every slider-crank mechanism used in commercial mechanical devices. However the nature of the mechanism does not allow a perfect balancing in such a way. The different nature of motions that govern the piston displacement and crank rotation imply that a counter mass can only statically balance the mechanism. An ideal dynamic balancing cannot be achieved this way. Therefore in this paper the excitations that act on the mechanism are split by the nature of motion that generates them and balanced accordingly. Two motions are defined, respectively the motion of the piston and the motion of the crank. The inertia force associated with the crank motion is balanced by building a dynamically equivalent system around the axis of the crankshaft while the excitation associated with the motion of the piston is balanced with a progressive spring with two rates.

Full text

Abstract:

A physical and corresponding theoretical model of a slider-crank mechanism is presented that approximates the single mode response of a continuous beam under a time periodic excitation in which the spatial distribution of the forcing is in the form of a half sine wave. The purpose of the model is to investigate the existence of chaos in systems having rigid members, as opposed to the highly flexible structures most often seen in chaotic demonstrations. The experimental construct displays complicated dynamical responses, including chaos, while the idealized theoretical model only supports the existence of a period one response. However, it is shown that the addition of an extremely small external perturbation will cause the response to demonstrate what appears to be a robustly chaotic response. A comparison of the Lyapunov exponents between this construct and the experimental model show close agreement.

The result proves that the locations of revolute joint of rocker and frame, the locations of revolute joint of link and block, the vertical location of revolute joint of upper link and rocker, the horizontal locations of revolute joint of upper link and link are almost no impact on the driving torque of crank. The locations of revolute joint of crank and upper link, the horizontal location of revolute joint of upper link and rocker, the vertical location of revolute joint of upper link and link have less impact on the driving torque of crank. The locations of revolute joint of crank and frame have greater impact on the maximum driving torque of crank.

This paper revisits a classical problem in kinematics, specifically determination of the crank position corresponding to the maximum velocity of the slider in the centric slider-crank mechanism.

Abstract Dynamic behaviour of a slider–crank mechanism associated with a smart flexible connecting rod is investigated. Effect of various mechanisms' parameters including crank length, flexibility of the connecting rod and the slider's mass on the dynamic behaviour is studied. Two control schemes are proposed for elastodynamic vibration suppression of the flexible connecting rod and also obtaining a constant angular velocity for the crank. The first scheme is based on feedback linearization approach and the second one is based on a sliding mode controller. The input signals are applied by an electric motor located at the crank ground joint, and two layers of piezoelectric film bonded to the top and bottom surfaces of the connecting rod. Both of the controllers successfully suppress the vibrations of the elastic linkage.

Mechanical generators of power pulses can be based on the various mechanisms, many of which are among the mechanisms of a variable structure.The Machinery Researching Institute of National Academy of Sciences of Kyrgyz Republic has offered to use the crank-slider mechanism of a variable structure with a disjointed slider in the shock machines. The operation aspect of this mechanism is that at the beginning of the working course a lead (drive dog) and a hammer block, which form the slider, make a joint movement, are separated when the lead movement slows down, and then upon the shock of the hammer block to the tool and the mechanism being under idle operation these two parts again make a joint movement.The shortcoming of this mechanism is that its coefficient of the changing average speed of the slider is equal to unit. But as to the shock machine, it is desirable for this coefficient to be higher than one. In this case the average speed of the slider at the working course will be higher than when idling, and the hammer block can have the higher speed. Also it should be noted that when idling there are more favorable conditions to fix the hammer block, which has made a rebound after the shock to the tool, with a lead at great values of the coefficient of the changing average speed of the slider.The coefficient of the changing average speed of the slider can be increased through the crank support shift in direction, perpendicular to the trajectories of the slider movement, by converting an axial mechanism into the non-axial one. Based on the specified values of frequency and energy of blow and also conditions for ensuring the working capacity and compactness of the shock machine, the paper makes synthesis of key parameters of the operating member of the non-axial slider-crank mechanism with the disjointed slider.

Abstract:

This paper presents a systematic methodology for the design and analysis of an offset slider-crank mechanism with a translating roller-follower. In the proposed approach, a generic kinematic model of the offset slider-crank and roller-follower is constructed using a homogenous coordinate transformation method and the slider cam profile are then derived using conjugate surface theory. The pressure angle and principal curvatures of the designed slider cam are analyzed based on the analytical expression of the cam profile. Finally, the NC data required to machine the slider cam are produced by equating the ability matrix of the 3-axis CNC machine tool with the desired tool location matrix.

Abstract:

Shaking table is an important component in rapid detection system of microorganisms. Based on the discussion regarding the advantage and shortage of the shaking table, this paper proposed a simple, reliable, and low-cost automatic shaking table. Three mechanisms were discussed with the achievement of reciprocating motion: slide-crank mechanism, follower-cam mechanism, and incomplete gear mechanism. The three mechanisms were compared in mechanical motion pair, motion form, component design, and manufacturing process. The slide-crank mechanism was finally determined. To overcome the strong oscillation of the liquid in the test tube along a single direction, this paper improved the slider-crank mechanism, and whose trajectory was modified into an irregular circle.

Abstract:

The Scotch yoke in its various forms and inversions has received considerable attention as a possible alternative to the slider-crank for internal combustion engine use. As a recent entry, the Stiller-Smith mechanism has shown promise as being a viable and strong option. Kinetostatic models were formulated to determine loading within similar eight-cylinder, four-stroke, compression-ignition engines. Emphasis was placed on comparing the number and similarity of mechanism components, implications of component and linkage motions, and the severity of loading experienced by similar bearing surfaces within the engines. It was found that journal bearings in the slider-crank engine were more severely loaded than those in the Stiller-Smith engine. The linear reciprocating bearings in the Stiller-Smith engine were more heavily loaded than the slider-crank piston skirts. Implications of these and other results are discussed.

Abstract:

Compared with crank-slider mechanism, the elbow-bar mechanism has some better dynamic and kinematic (D&K) characteristics for transmitting movement and force as the ultimate output component in mechanical press. The relations of the position, speed and acceleration of the driving and driven components, as the D&K characteristics of crank-slider mechanism, are quite important for analysis and design of the transmission mechanism and its components. All D&K characteristics of each components are established by analytical method, then the numerical simulation is carried out on the base of analytical euqations.

Abstract:

The degree of freedom for a multi-link drive mechanism of a 50kN miniature servo press was calculated. The kinematics equations of the mechanism was established based on the rod group method. The choice or design basis for rod length and some hinge points were proposed. The multi-linkage mechanism’s line segment model was constructed in SolidWorks and a set of design parameters was obtained that met the requirements. The M file of kinematic equations were wrote and calculated in Matlab and the displacement, velocity and acceleration curve of the slider were obtained. Compared with the crank-slider mechanism, the mechanism has the features of quick return, small return speed, slightly smaller speed and larger acceleration near B.D.C. Therefore, the speed and acceleration characteristics of the mechanism were inferior to the crank-slider mechanism in the case of reverse rotation and higher speed.

Abstract:

A new 1-DOF mechanical press with a geared eight-bar linkage mechanism is presented. The proposed press can generate the required kinematic and dynamic performance for drawing, stamping, deep drawing, and precision cutting processes by simply adjusting the offset of the ram. The press consists of an elementary planetary gear train with a pair of planet gears, a slider-crank mechanism, and a slider-crank mechanism with a variable-length crank. The configuration and a solid model are described, and a kinematic analysis, dynamic analysis, and optimized dimensional synthesis of the press are discussed. Examples are provided to verify the feasibility and effectiveness of the design methodology. The proposed press could lead to more flexible and cost-effective applications.
