摘要
以某轻型载货汽车驾驶室悬置系统为研究对象进行道路试验,并建立了3自由度驾驶室悬置系统的ADAMS模型。对比仿真与试验结果发现,该驾驶室前、后悬置共振频率吻合,第3阶固有频率处于共振频率范围内,为此提出了将后悬置垂向刚度降低20%的优化方案。道路试验结果表明,在不同车速下,优化后的驾驶员座椅处加速度均方根值均降低,驾驶室舒适性得到较大改善。
In this paper,a road test was carried out to study a light truck cab suspension system.A 3-DOF ADAMS model of the cab suspension system is built.When comparing the road test results to the simulation results,we found out that the resonance frequency of the front and rear suspension agree well with each other but the third-order natural frequency is within the resonance frequency range,therefore the authors propose an optimization plan to reduce the rear suspension vertical stiffness by 20%.The results of road test show that the driver＇s seat acceleration RMS values are lowered at various speed,therefore,cab comfort is greatly improved.
