| 摘 要： | 为分析某牵引车在比利时路上的车架疲劳，建立该牵引车整车多体动力学模型。将试验测得的车轮六分力加载到模型中进行仿真分析，并与试验结果对比，验证模型的可信性。提取多体动力学仿真结果中的车架载荷历程，基于模态应力恢复理论对车架进行疲劳分析，预测车架疲劳寿命。仿真结果表明该分析方法可作为车架疲劳分析的有效手段。

| Abstract: | To analyze the fatigue of a tractor frame on Belgian road, the multi body dynamics model of the tractor is built. The six component force of wheel measured by experiment is loaded into the model for simulation analysis, and the credibility of the model is verified by comparing with the test results. The frame load history in multi body dynamic simulation results is extracted. The frame fatigue analysis is performed based on modal stress recovery theory and the frame fatigue life is predicted. The simulation results show that the analysis method can be used as an effective method for frame fatigue analysis. |
