摘　　要：利用ADMAS软件,建立了某道路清扫车的整车动力学模型。在利用离散梁原理建立等效板簧模型时,考虑到离散梁参数较难确定的特点,采用了参数反求的建模方法。以整车动力学模型为基础,分析了清扫车在工作时平顺性较差易导致的问题。同时,以清扫车工作时的平顺性改善为目标,对该车前悬架系统参数进行了优化,结果表明优化后清扫车工作时的平顺性得到了提高。Abstract A dynamics model of vehicle was set up by using ADAMS software. As the parameters of discrete beam is difficult to be determined, discrete beam principle is chosen to establish an equivalent leaf-spring model by using the method of inverse parameter. Based on the vehicle model, the smoothness of the modified sweeper is analyzed while running. In order to improve the smoothness, front suspension system parameters of the vehicle were optimized; the results indicated that the smoothness of the optimized sweeper has been improved.
