Evaluation of the limit properties of a solid body system

Abstract

This article discusses the design of modern wheel-transport vehicles, in which the problem of reducing the level of vibrations and shocks arises, since the quality and performance, reliability and durability of the operation of machines, devices and equipment depend mainly on the resulting fluctuations during their operation. Also, solutions of problems concerning the limiting properties of solid-state systems for cases of harmonic and shock effects are discussed. The design model of many technical objects is a solid body, which is onboard radio electronic equipment (REA). For the selected model of a solid body, a system is designed for the vibration isolation of a block, at s points of which there are electrical radio-sensitive elements that can withstand a given limiting vibration acceleration. The synthesized vibration-proof system is implemented with the help of linear passive elastic-damping suspensions and active elements, which represent an ideal servo-mechanism.
