摘要
运用ADAMS软件建立了国内某大客车的底盘动力学模型,根据国家标准进行仿真并验证了模型的正确性。以空气悬架导向机构结构参数为试验因素进行正交试验,找出了影响转向特性的主要结构因素。对导向机构结构参数组合进行信噪比分析,得到信噪比最大的导向机构结构参数组合,同时,也验证了空气悬架导向机构的结构参数对整车的转向特性有重要影响。
Based on a real vehicle parameters to establish a bus chassis dynamic model with ADAMS, according to the national standard to simulation, and verified the validity of the model ; air suspension guide mechanism parameters were selected as factors in this orthogonal experiment. The main factor which effects the turning performances is found. Use of signal-to-noise ratio, has carried on the calculation for the data from simulation, obtained parameter combination which signal-to-noise ratio is maximum. At the same time, it is also proved that the structure parameters of the air suspension guide mechanism have important influence on the vehicle steering characteristics.
