摘　　要：应用动力学软件Adams/Car搭建大型矿用车单边连通式后油气悬架系统虚拟样机模型,并对悬架系统模型进行静态载荷仿真试验和双轮同向跳动仿真试验。仿真结果显示,随车轮轮跳量的增加,悬架系统的轮心力、前束角及主销后倾角的变化范围均与实际情况十分吻合。基于所建立的虚拟样机模型,对悬架系统进行参数优化,通过DOE筛选出对于优化目标参数影响较大的硬点并优化硬点坐标。优化后,悬架系统减振性能明显提高,悬架系统运动学特性也同样得到改善。The dynamics software Adams/Car is applied to build a virtual prototype model of the unilateral interconnected rear hydropneumatic suspension system of a large mining truck,and static load simulation tests and two-wheel codirectional runout simulation tests are conducted on the suspension system model.The simulation results show that,with the increase of wheel run-out,the variation range of the wheel center force,toe angle and kingpin caster angle of the suspension system is very consistent with the actual situation.Based on the built virtual prototype model,the parameters of the suspension system are optimized,the hard points that have a greater influence on the optimized target parameters are selected by DOE,and the coordinates of the hard points are optimized.After optimization,the damping performance of the suspension system is significantly enhanced,and the kinematics characteristics of the suspension system are also improved.
