针对某车型扭力梁后悬架出现疲劳断裂的问题，提出了试验方法与计算机辅助工程（ CAE）方法相结合的一体化疲劳分析方法，即利用汽车试验场耐久性试验、MSC PATRAN、MSC NASTRAN、MSC ADAMS分析软件和人工神经网络算法，有效解决疲劳寿命分析中的三个关键问题：快速准确的有限元模型的建立、疲劳应变的计算、疲劳寿命预测。以扭力梁后悬架疲劳寿命分析为例，对比试验测试结果与仿真分析结果表明该一体化疲劳寿命分析方法能在汽车设计开发阶段准确预测汽车零件疲劳寿命。

Aiming at solve a torsion beam rear suspension models fatigue fracture:problem, an integrate fatigue analysis method combining test method and digital CAE method is proposed. This method integrates the use of three analytical tools: Automotive Proving Ground durability test, MSC PATRAN, MSC NASTRAN, MSC ADAMS three analysis software, artificial neural networks. Comparing test results and simulation results, it shows that the method can accurately predict the fatigue life of automotive parts in automotive design and development stage.
