| 摘 要： | 采用虚拟试验场技术进行了汽车行驶平顺性的时域仿真。建立了面向汽车平顺性分析的整车刚弹耦合有限元模型,同时建立了脉冲输入路面模型和随机输入路面模型。采用1/3倍频带分布加速度均方根值方法及总加权方法对试验车辆的平顺性进行了评价。试验结果表明,运用虚拟试验场技术能够真实地反映汽车的行驶平顺性,仿真分析结果可靠。

| Abstract: | Apply virtual proving ground technology to simulate the time-domain of vehicle ride comfort.The complete vehicle rigid-elastic coupling FE model toward vehicle ride comfort, pulse input road surface model and random input road surface model are established.Apply 1/3 times frequency range distribution acceleration root-mean-square value method and weighted method to evaluate the ride comfort of test vehicle.The test results show that the virtual proving ground technology can reflect the vehicle ride comfort factually,and the simulation results are reliable. |
