| 摘 要： | 采用逆虚拟激励法进行车辆行驶随机动载的识别,使用确定性方法求解了车辆平稳行驶动载的识别问题.即已知车辆振动响应的自谱与互谱,在反求路面激励功率谱的基础上,求出车辆行驶动载.并通过计算机模拟识别动载.研究结果表明,根据前轮的响应模拟出的车辆随机动载能较好地反映车辆在不同速度,不同路面上的变化.逆虚拟激励法在求解车辆随机动...

| Abstract: | Research was conducted on an inverse pseudo excitation method for vehicle dynamic load identification.When a vehicle is in stationary random vibration,using a deterministic method solves the vehicle dynamic load spectrum recognition problem.The auto-PSD and cross-PSD of vehicle vibration response are known.Based on reversing the power spectrum of road excitation,vehicle dynamic load PSD was obtained.An inverse pseudo excitation method for solving the vehicle dynamic load spectrum showed good solution accura... |
