摘要
Considering the incompressibility of fluid, the vertical velocity and acceleration of multi-axle vehicle with hydraulic suspension caused by road roughness can be expressed by a trigonometric series with phase angle as argument, and the sum of series can be reduced to an analytic formula, which approximates to the linear function of vehicle speed. Analyses show that increasing the axle number of multi-axle vehicle can effectively suppress the dynamic load on frame and suspension, but with the increase of vehicle speed the suppression effect constantly weakens and finally the vehicle behaves as a singular axle one.
