Vibratory equipment is widely used for performing various finishing processes, machining and forcing of different parts and materials. Numerous researchers and technologists pay specific attention to the possibilities of implementing vibration-driven machinery for conducting the lapping and polishing operations on flat surfaces. The present paper is dedicated to studying the laps kinematic parameters of the vibratory finishing machine actuated by six electromagnets. The paper’s scientific novelty consists in the experimental verification of the previously modelled and simulated circular trajectories of the laps under different operational conditions. The methodology of research contains two basic stages: changing the excitation frequency at the constant traction force and changing the traction force at the constant excitation frequency. The improved 3D-design of the vibratory finishing machine was developed in the SolidWorks software. The experimental prototype was implemented in practice, and full-scale tests were carried out using the WitMotion sensors and software. Based on the obtained experimental data, the trajectories of the machine’s laps were constructed and analyzed in the MathCad software. The research results substantiate the possibilities of providing circular oscillations of the laps at different operational conditions. The results can be used by technologists and engineers while choosing the appropriate design and control parameters for similar vibratory equipment intended for lapping and polishing of flat surfaces.

The research object is a pneumatic spring of a modern rolling stock. Using a two - mass calculation scheme, the diagrams “force-deformation” of a pneumatic spring are designed at driving speed of 160-200 km/h and high-speed driving of 201-250 km/h. It is determined that when the diameter of the connecting pipeline is changed from 20 to 35 mm, the inclination angle of the diagram “force - deformation” of the pneumatic spring is changed at speed driving from 32 degrees up to 57 deg.; at high-speed driving from 30 deg. up to 48 deg. It is proposed to determine a pneumatic spring operation coefficient using the forms of the designed diagrams “force - deformation.” Studying the specified coefficient in the speed range from 160 to 250 km/h, and the connecting pipeline diameter from 20 to 35 mm showed that the values of the pneumatic spring operation coefficient vary from 0.089 to 0.24, and the dependencies are nonlinear. Using the pneumatic spring operation coefficient will make it possible to further evaluate the pneumatic spring suspension system operation depending on the operating conditions of the railway vehicle.

Vibratory treatment is widely used in various industries for performing finishing technological operations, e.g., lapping, polishing, glazing, strengthening (hardening), etc. The problems of maximizing the treatment accuracy and performance of vibratory technological equipment provide the necessity of optimizing the motion trajectory (path) of the corresponding working member. The main purpose of these investigations is to substantiate the possibilities of generating the translational (reciprocating) motion and plane (plane-parallel) oscillations of the working members of vibratory lapping-polishing machines. The research methodology consists of the following stages: substantiating the ideas of improving the vibratory lapping-polishing machines; designing the dynamic diagrams of the machines’ oscillatory systems; developing the mathematical models to describe their dynamic behavior; numerical modeling of the machines’ motion conditions. The obtained results present the possible motion trajectories (paths) of the working member (lap, polisher, grazer, etc.). The main scientific novelty of these investigations is substantiating the idea and possibilities of implementing various motion conditions of the working member for adjusting the vibratory lapping-polishing machine in accordance with the technological requirements, as well as for increasing the wear-out period and durability (normal operating period) of the working member. The obtained results can be used for improving the performance and accuracy of similar vibratory lapping-polishing machines.
