Abstract:

Focusing on the requirements of safety and reliability of fuze setback arming device of rocket-assisted projectile, a zigzag groove setback device with two degree of freedom was designed with Inventor 6. The dynamic simulation is developed under environment of VisualNastran. The optimum parameters of up inertia-cylinder mass, down inertia-cylinder mass, up inertia-spring rigidity and down inertia-spring rigidity were tested by orthogonal method and simulated. The results indicate that this setback device can effectively differentiate setback overload in launch and impact overload at service ha

Abstract:

By means of inertia-moment method, formulae are derived for calculating flexural rigidity of RC beams under different loading stage, which can be used for calculating initial rigidity and rigidity in service stage. Involving less parameters, it’s convenient to use the formulae. As for four examples, calculations are carried out by both code method and formulations given in this paper, and satisfied results are shown. Further more, based on finite rib method, nonlinear-all-rang analysis is done for M-B of beam sections.

Purpose. The main purpose of our work is to substantiate the geometric parameters of a variable moment of inertia pulley, which can reduce the weight of a drive with such a pulley. Methodology. It was found that the masses of the pulley and support elements have the greatest influence on the weight of the drive, so we focused on the pulley. Improvement of the pulley design and determination of its rational geometric parameters were carried out in three stages. At the first stage, the size of the rim was reduced in accordance with the diameter of the rope. At the second stage, a multivariate ca

The paper develops methods of system analysis and technologies for control dynamic conditions of technical means of railway transport. Methods of structural mathematical modeling are used, within the framework of which the design scheme of the object, considered as a mechanical oscillatory system with several degrees of freedom, is interpreted as a dynamically equivalent automatic control system. The problems of the dynamics of the coupling of two freight railway carriages with two variants of its rigidity (conventional and rigid hinge-type fastening) are considered. It is shown that with a ce

Abstract:

The paper proposes an experimental technique for finding the uneven distribution of torque between the gears of a planetary gear and, at the same time, the distribution of the load along the tooth based on five load sensors on the shaft of each planetary gear. The object of study is the rigidity and inertial parameters of the planetary gear elements. The purpose of the study is to create a dynamic model of a planetary gear to calculate forced vibrations caused by time-varying gaps - tensions arising in gears. The paper provides an analysis of the problem for the developed model and factors tha

Abstract:

The paper considers the hydrodynamic limitations in the combined machining, caused by the non-rigidity of the tubular cathode-tool. It is shown that increasing the inertia moment of the cathode-tool cross section is possible only in decreasing the diameter of the hole for pumping the electrolyte. It should be noted that reducing the diameter of the hole increases the hydrodynamic losses of the electrolyte flow in the hydraulic path and, as a result, leads to a significant reduction in the range of the mode regimes. Thus, to implement the combined piercing of deep holes of small diameter, it is

Abstract:

Development of the model range of high-speed inline small diesels by designing a six-cylinder version based on the already adjusted four-cylinder one, entails a decrease in the rigidity of the crankshaft. This in turn reduces its reliability due to the enhanced impact of torsional vibrations. To assess this impact, we performed a series of calculations for determining the amplitudes and tangential stresses in the crankshaft system. In order to reduce maximum values of angular amplitudes and tangential stresses, the most expedient is to use a silicone damper for absorbing the torsional vibratio

A first known investigation into the vibratory characteristics of rectangular Mindlin plates with intermediate stiffeners is presented. The Rayleigh-Ritz method is used, with displacement and rotational functions assumed in the form of mathematically complete algebraic polynomials. Sets of numerical frequency parameters for rectangular plates of various boundary conditions, thicknesses and plate dimensions are presented. In the study, the effects of shear deformation and rotary inertia on the vibrational response of the plate structures are investigated. The influence of torsional rigidity and

If regarding the inertia force of the robot system as the external force, the robot system will become a static system. The rigidity can be analyzed using the screw theory, then we establish the dynamic error modle which is caused by the inertia force and gravity.

Abstract:

Abstract High levels of dynamic loads in a modem diesel engine take place at low frequencies and are connected with the forced vibration of the engine under the action of excitation gas and inertia forces. The lower range of these frequencies are equivalent to the speed of the engine (two stroke) and half engine speed (four stroke). They lead to high stress levels and deformations and often cause internal damage or component failure as well as increasing vibration transmitted to the foundation. One of the most important factors in improving the reliability and durability of engine components a

Abstract:

Unstable vibrations of a two-blade wind turbine tower are theoretically investigated. The theoretical model is a five-degree-of-freedom (5DOF) system, however, the equations of motion are derived separately for 3DOF subsystem (I) and 2DOF subsystem (II). Parametric excitation due to the asymmetry of the moments of inertia of the blade rotor is included only in subsystem (I). Frequency equations are derived and natural frequency diagrams are calculated to clearly demonstrate both the rotational speeds where unstable regions appear and which type of unstable vibrations may occur. It is found tha
