本文以某型号电动轮自卸车为研究对象，应用多体动力学仿真软件SIMPACK建立整车虚拟样机模型，并采用谐波叠加法原理构建C级路面，建立了整车动力学行驶的仿真平台。为验证仿真模型的正确性，在神华集团（新疆）准东露天煤矿利用DH5902数据采集分析系统对自卸车进行行驶性能试验，测量了驾驶员座椅处的振动加速度。结果表明：试验结果与仿真计算结果比较接近，该型号电动轮自卸车平顺性研究中所采用的数学模型较为准确，且精度较高。
本文以某型號電動輪自卸車為研究對象，應用多體動力學倣真軟件SIMPACK建立整車虛擬樣機模型，併採用諧波疊加法原理構建C級路麵，建立瞭整車動力學行駛的倣真平檯。為驗證倣真模型的正確性，在神華集糰（新疆）準東露天煤礦利用DH5902數據採集分析繫統對自卸車進行行駛性能試驗，測量瞭駕駛員座椅處的振動加速度。結果錶明：試驗結果與倣真計算結果比較接近，該型號電動輪自卸車平順性研究中所採用的數學模型較為準確，且精度較高。

By taking a certain type of electric wheel dump truck as the research object, this paper builds a ve-hicle virtual prototype model based on multi-body dynamics simulation software SIMPACK. We also build vehicle driving dynamics simulation platform based on the vehicle virtual prototype vehicle and C-class road. To verify the correctness of the simulation model, we carry out the dump truck driving performance testing in the Xinjiang Shen-hua Zhundong opencast coal mine with the DH5902 data acquisition and analysis system, and measure the vibra-tion acceleration of dump truck driver's seat. The results show that:the test results and the simulation results are closed. Therefore, the mathematical model adopted in the research of electric wheel dump truck's ride comfort is relatively accurate and is of high-precision.
