摘要
对某自卸车进行道路试验,采集不同速度及路况下的振动信号并进行分析,建立了驾驶室悬置系统多体动力学仿真模型。针对3种典型工况,以前、后悬置弹簧刚度与减振器阻尼为因子,运用ADAMS优化模块对驾驶室悬置参数进行优化,得出3组适合该车型的参数匹配值,并在此基础上应用正交试验技术对这3组值进行再优化,最终确定1组适合3种典型工况的驾驶室悬置最佳匹配值。
In this research, road test is conducted for a dump truck and the vibration signals under different speed and road conditions are acquired and analyzed, and a multi-body dynamics simulation model is established for the cab suspension in ADAMS. For the three typical conditions, ADAMS optimization module is applied for parameters optimization of the cab suspension system with stiffness of the front and rear suspension spring and the damping as test factors, to obtain three groups of parameter matching values suitable for this model. And on this basis, orthogonal test technology is used for re-optimization of these three groups of values. Finally the paper determines a group of optimal matching values suitable for three different conditions of the truck.
