一种燃气轮机车前支撑有限元分析的研究

Research on Finite Element Analysis for Front Bolster of a Gas Turbine Vehicle

前支撑是承载发动机的重要结构,承受着来自燃气轮机的压力和冲击。通过Solid Works建立三维设计模型,利用Simulation模块,通过考察车辆停止和行驶中的两种工况,对前支撑分别进行了静态分析和疲劳分析。有限元分析的结果验证了结构设计的可靠性和安全性,为前支撑的优化设计提供了计算方法和理论依据。直接应用Simulation模块对采用Solid Works建立的三维模型进行有限元分析验证,有效避免了数据转换缺陷等问题,为机械产品的设计和分析提供了一种实用的简便方法。

Front bolster is important structure bearing weight of gas turbine engine, it bears the pressure and impact from gas turbine engine. 3D design model is built in SolidWorks,and the Simulation module in SolidWorks is used to study the stop and driving situation of vehicle. The static and fatigue analysis of front bolster are carried out. Results of finite element analysis verify the credibility and safety of structure ,and provide calculated method and theory basis. Directly using Simulation module in the finite element analysis of 3D-model designed by SolidWorks can efficiently solve the problem of numerical exchange. This paper provides a practical and convenient reference for the design and analysis of mechanical products.
