摘要

针对自主研发的某型8X8轮式车辆半主动油气悬挂,首次开展了以实地跑车试验为基础的振动测试分析,给出了阻尼可调油气弹簧的结构简图以及半主动悬挂的控制原理,通过试验和曲线拟合的方式得出了电磁阀在不同电流下的流量系数。分别在起伏路和高速公路两种典型路况下,对车身不同位置的垂直振动加速度进行测试,验证了在实现阻尼实时调节的前提下,各测点加速度均方根值较被动式悬挂均得到了有效抑制,从而显著提高了车辆的整体行驶性能,所取得的第一手试验数据为国内在半主动悬挂方面的工程设计提供了参考。

Abstract

The vibration test was developed for the first time with regard to the self-improving semi-active hydro-pneumatic suspension of 8X8 wheel-type vehicle, and the diagram of the damping controlled hydro-pneumatic spring and the control principle of the semi-active suspension were given. After that, the coefficients of flow of electromagnetic valve in different current strength were got through experiment and curve fitting. In the situations of wave road and express highway, the vertical vibration accelerations at different points on the vehicle body were tested. This validates that the mean square root value of the acceleration of each test point has been restrained efficiently while damping real-time adjustment is realized, so that the vehicle ride performance has been improved significantly. The obtained test data can offer reference to the design of the semi-active suspension interiorly.
