Dynamic-damping hydraulic suspension system

Mechanical engineering

The object of the study is an original hydraulic suspension system with dynamic damping (DDHS) which suppresses resonant frequencies by using modern (inert) components such as silicone oil and Nitrogen gas with automatic regulation of pressure in the gas chamber. A calculation of the installation was carried out in order to determine whether it can effectively influence the mobile energy suspension with the DDHS system to improve the operator's traffic conditions and the main technical indicators (performance, reliability, economy, ergonomics. Based on the theoretical frequency characteristics obtained, conclusions are drawn about improving the conditions of motion of the operator. It was found that it is possible to suppress unfavorable frequencies by deflecting them to the off-resonance region; a reduction of these frequencies by 27,7 % was observed, due to dissipative properties of silicone oil, which provides stable performance.
