| 摘 要： | 通过谐波叠加原理,在现有的二维路面谱的基础上,从空间路面频率谱出发,将之拓展到三维空间内的路面谱,并给出模拟随机路面谱的方法.通过对该路面谱模型进行谱分析,对其功率谱密度进行了验证.建立了某履带车辆单自由度悬挂质量振动系统的力学模型,以三维路面谱模型作为虚拟激励输入,实现了对单自由度履带车辆振动系统的动态模拟.

| Abstract: | Three-dimensional road surface spectrum model was established based on two-dimensional road surface spectrum model with harmonic wave superposition method.The road surface spectrum was analyzed and its power spectral density was validated.A single-degree-of-freedom tracked vehicle vibration system was constructed.Dynamic simulation on single-degree-of-freedom tracked vehicle vibration system was realized using the three-dimensional road surface spectrum model as virtual excitation input. |

| Keywords: | three-dimensional road surface spectrum vehicle vibration model virtual excitation method |
