| 摘 要： | 通过计算机仿真模拟了在路面随机输入下驾驶室底板的振动响应;利用Nastran软件对车身的有限元模型进行模态抽取,建立了刚弹耦合模型;对多刚体模型、刚弹耦合振动模型的计算结果与试验进行了对比,验证了模型的正确性;以驾驶室悬置的弹簧刚度、减振器阻尼为影响因素,通过虚拟DOE正交试验分析,显著改善了驾驶室的乘坐舒适性。

| Abstract: | A simulation is carried out on the vibration response of truck cab floor to random road inputs.The modes of the cab are extracted by using Nastran software,and the rigid-elastic coupling model and multi rigid body model for cab are constructed,simulated and verified by tests.The spring stiffness and damping of the cab suspension are optimized by virtual DOE analysis,so the ride comfort of cab is markedly improved. |
