Research on the Mathematical Modeling of Damping Controlled Oil Gas Spring

摘要

In order to improve the vehicle performance, the mathematical model and experimental research of damping controlled oil gas spring were carried out in this paper, a proportional throttle valve was installed on the basis of the original damping valve system. The proportional valve adopted slide valve structure and had 15 gear adjustment positions, through regulating the current intensity to achieve the purpose of controlling valve opening and flow. After that, the flow coefficient was fitted by comparing the valve flow through the flow test, which could make the analytical calculation of damping characteristics realize conveniently. Compared with the experimental data, the maximum calculation error could be controlled to 5.6%.
