The Analysis of the Influence of the Independent Suspension on the Comfort for a Mine Truck

Abstract

In order to solve the problem that the low speed and driving fatigue of mine trucks caused by its poor buffer and damping of the suspension, the hydro-pneumatic independent suspension is adopted instead of the traditional leaf spring dependent suspension for the mine truck in this paper. On this basis, the mathematical model of the hydro-pneumatic spring is established; subsequently the kinetic models of the suspension are built in MATLAB/Simulink; then the comfort tests of the suspension for the leaf spring and hydro-pneumatic spring successively; The results show that the hydro-pneumatic spring can improve the comfort of the mine truck compared to the leaf spring, consequently enhances the truck speed and alleviates the driving fatigue.
