矿用自卸车半车半主动悬架俯仰数学模型的建立

Mining of the dump truck half vehicle semi-active Suspension pitch for the establishment of the Mathematical model

悬架系统是车辆系统中重要的组成之一。悬架系统分为被动悬架、半主动悬架、主动悬架。悬架系统性能的优劣对车辆的乘坐舒适性、操纵稳定性、平顺性、车辆安全性都有重要影响,我国矿用自卸车悬架系统多为被动悬架,矿用自卸车半主动悬架系统的研究相对较少,因此精确的建立矿用自卸车半主动悬架系统的数学模型对矿用自卸车半主动悬架系统的研究具有非常重要意义。该文针对某重型矿用自卸车悬架系统进行了力学分析,根据经典力学定律推导出了矿用自卸车悬架系统的部分力学微分方程,为进一步研究矿用自卸车半主动悬架系统提供了理论基础。

Suspension system is one of the important assembly of the vehicle system. Suspension system is divided into passive suspension, semi--active suspension and active suspension. The merits of the suspension system performance of vehicle ride comfort and handling stability, comfort, vehicle safety has important influence, Our country mining equipments suspension system to passive suspension, mining equipments of the semi--active suspension system study is relatively small, So accurate establishment of mining equipments, the mathematical model of the semi--active suspension system for mining equipments of semi--active suspension system research has very important significance. In a heavy mining of the dump truck for the mechanics analysis, and mining of the dump truck is deduced according to the taws of classical mechanics suspension system parts of mechanical differential equation, for further research of mining of the dump truck semi--active suspension system provides a theoretical basis.
