摘要
针对改善载货汽车行驶平顺性问题,以某型号载货汽车驾驶室悬置系统为研究对象,对驾驶室悬置系统进行参数优化设计。首先在ADAMS中建立载货汽车整车动力学模型;其次,采用DOE实验设计方法,对驾驶室悬置系统参数进行灵敏度分析,以驾驶室座椅测试点处的加速度RMS值来评价整车平顺性的优劣情况,选取对整车平顺性影响较大的性能参数进行优化设计,并对比优化前后座椅导轨处加速度响应。结果表明,优化后座椅导轨X向加速度RMS值降低16.8%,Z向加速度RMS值降低13.5%,载货汽车整车平顺性得到明显提高。
In order to improve the ride comfort of trucks,the suspension system of the cab of a certain type of trucks is studied.The parameters of the mounting system are optimized.Firstly,the vehicle dynamics model of the truck is established in ADAMS.Secondly,the sensitivity analysis of the parameters of the cab mounting system is carried out by using DOE experimental design method.The ride comfort of the whole vehicle is evaluated by the RMS value at the testing point of the cab seat.The performance parameters which have a great influence on the ride comfort of the vehicle are selected to optimize the design and verify the test results of the real vehicle.The results show that the ride comfort is raised by 13%.It is proved that this method is reasonable and effective to improve the accuracy of the model and the ride comfort of the whole vehicle,and it has practical value in engineering.
