Abstract

The article presents materials related to the development of a promising design of a hydraulic damper in-stalled in the suspension of vehicles used in the agro-industrial complex. A special feature of the hydraulic damper design is the transition from vertical channels to horizontal channels in the piston and stem of the vi-bration damper. In this case, the vertical sections of the rod channels are mated with the horizontal sections of the piston channels. The presence of such calibrated holes in the piston and rod, as well as due to the ab-sence of bypass valves, can significantly reduce sudden pressure changes in the vibration damper during high-speed movements of both the rod and the piston. This significantly increases the smoothness of the ride, and, consequently, the comfort and safety of the vehicle and, thus, improves the working conditions of the personnel operating it. Analytical studies have been carried out, as well as hydrodynamic and strength calcu-lations of such determining parameters as the pressure of the working fluid and its flow rate. Recommenda-tions are given on the choice of rod and piston material for a promising design of a hydraulic damper for ve-hicles. A method of engineering calculations for determining the parameters of the throttling system is pro-posed, which allows to establish the criteria for the operability of the developed technical solution with a view to its possible application in industrial conditions.
