In this article, an investigation on non-linear dynamical behaviours of a transmission system with a gear pair is conducted. The transmission system is described through an impact model with a possible stick between the two gears. From the theory of discontinuous dynamical systems, the motion mechanism of impacting chatter with stick is investigated. The onset and vanishing conditions for stick motions are developed, and the condition for maintaining stick motion is obtained as well.

Abstract:

As the car moving, the power of the engine is transmitted to the active wheel through the transmission system. In such a transmission, the power is lost due to friction in the powertrain and the power of the active wheel will be less than the output of the engine. The transmission system consists of components such as clutches, transmissions, propeller shaft, active bridge, differential and active wheels. During the working process, each of these parts is affected by the individual factors that reduce their performance. This article is to analyze the structure, function, task and modeling of t

Abstract:

In this work, a rotational motion control of a washing machine featuring an electrorheological (ER) clutch/brake actuators is investigated. After analysing the field-dependent transmission and braking torques of the actuator on the basis of Bingham model, two sets of ER clutch/brake actuators are manufactured. The dynamic model of the actuators is then formulated by considering time constants. Subsequently, the actuators are applied to a small-sized pulsator type washing machine for rotational motion control. The control system model represented by spin-basket and pulsator motions is establish

Abstract:

Ultra-high-voltage (UHV) cup-type transmission towers supported with long-span transmission lines are unavoidably subjected to the coupling action between the towers and the transmission lines. Therefore, investigating how tower-line coupling affects UHV cup-type transmission towers is important. In this study, three shaking table array tests of an UHV cup-type transmission tower-line system were carried out to investigate the dynamic characteristics of the coupling action between the towers and transmission lines based on the following four comparative models: a single-tower model, a single-t

In order to investigate the effect of friction on gear system featuring confluence transmission, a non-linear dynamic model of three-gear system having two gear pairs was built. The influence of gear systems dynamic characteristics caused by changing of friction coefcient was researched. With the changing of friction coefcient, left-right gear pairs show dynamic behavior with coexist of same periodic motion, coexist of different periodic motion and chaos. With the increase of friction coefcient, the jump phenomenon of amplitude occurred, the impact of gear system became larger.

Abstract:

The vibratory excitation arising from a gear pair is widely recognized to be a consequence of the nonuniform transmission of motion by the gear pair. In the preceding paper in this issue, it is shown that a three-component transmission error is required to describe the nonuniform transmission of motion by bevel gears for vibration excitation characterization purposes. The expression for the three-component transmission error derived in that paper is combined in the present paper with an analysis of the mesh forces and mesh elasticity to yield an equation of constraint involving the six degree-

In a four-piston Stirling engine, Siemens configuration, the displacement of the pistons is governed by the motion transmission element, which converts the reciprocating motion of pistons into rotary motion. This study aimed to evaluate the influence of the geometry of the transmission element in the mechanical efficiency of a Stirling engine. Analyses were performed using a mathematical computer simulation that uses the geometric and operating data of the engine to calculate the mechanical power and efficiency through a first order thermodynamic mathematical model, also known as the Schmidtmo

Abstract:

This paper discusses a new approach for wireless motion control. Existing wireless techniques suffer from large closed loop delays of several milliseconds, which is unacceptable in precision motion systems. These large delays are mainly caused by the protocol used, since these are optimized for transferring large amounts of data, not to minimize transmission delay. A new protocol and wireless system are proposed that reduce the closed loop transmission delay to less than 300 microseconds. The system has been verified in a real control system, and measurements show the performance, which is mor

The operation environment of an electromechanical coupling transmission system in shearers is significantly harsher than that of electromechanical coupling transmission system for general applications. Besides, under the combined action of electrical and mechanical factors, unstable phenomenon may appear when the complicated dynamic behaviors of electromechanical coupling transmission system of a shearer occur such as bifurcation and chaos. Therefore, to solve this problem, the stability, bifurcation, and chaotic characters of electromechanical coupling transmission system with various electro

Abstract This study investigates the dynamic responses of gear systems while considering the morphology of worn gear tooth surfaces after different working times. Specifically, the anisotropic three-dimensional micro-morphology of the rough tooth surface model is established based on the W-B fractal theory. The non-uniform wear of the rough tooth surface under different rotational speeds and working hours is quantified according to Archard’s theory. The time-varying meshing stiffness (TVMS) and backlash are calculated with the wear values and then serve as internal excitation input parameters
