摘要 针对现有液压升降车车身窄、重心高,行驶过程中存在易侧翻等平稳性问题,为某型号液压升降车前桥设计了双横臂独立悬架.先建立空间拓扑图,采用空间解析几何方法得出车轮关键定位参数表达式,根据设计参数计算出关键定位参数;然后用多体动力学仿真软件ADAMS建立悬架的虚拟样机模型,进行运动学仿真优化,找出合理的车轮定位参数;根据仿真结果建立悬架实物分析模型,进行仿真结果与实验结果对比分析.结果表明:实验结果与仿真结果基本一致,各指标均满足了设计要求,验证了理论模型的准确性和仿真优化的可靠性. Aiming at the existing hydraulic lifting vehicle problems of narrow body and high gravity center with easy rollover in the process of travelling,the front axle of a certain hydraulic lifting vehicle is designed to be double wishbone independent suspension.First,the spatial topology is built,and the expression of key positioning parameters of the wheel is obtained by spatial analytic geometry,so that the key coordinate parameters can be calculated based on design parameters.Then,the virtual prototype model of the suspension is established by using multi-body dynamic simulation software ADAMS,and the kinematic simulation analysis and optimization are carried out to obtain reasonable wheel positioning parameters.Finally,the physical analysis model is built based on the simulation results,which are compared with the experimental results.The results show that the experiment results are basically consistent with the simulation results,and all indicators meet the design requirements,verifying the accuracy of the theoretical model and the reliability of simulation optimization.
