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.
