【摘要】 本文主要研究了轿车底盘零部件耐久性虚拟试验模型的建立方法。具体步骤为首先使用Hypermesh7.0建立了关键零部件的有限元模型并用试验验证,然后结合零部件的有限元模型和CAD数模使用LMS Virtuallab建立了刚柔耦合的虚拟试验模型,此模型为下一步的底盘目标零部件疲劳寿命分析创造了条件。更多还原

【Abstract】 This analysis described a method of building a car chassis components virtual prototype for durability analysis.Firstly Hypermesh7.0 was used to build the finite element analysis(FEA) models of key components and the models were modified by the test result.Then the FEA models and CAD models were combined through the LMS Virtuallab.Motion to build the rigid-flexible hybrid model for virtual tests.This model can be used to analyse the fatigue life of the car chassis components in the next step.更多还原
