大型真空容器主要机械结构受力分析及优化

The Main Mechanical Structure of Large Vacuum Container Force Analysis and Optimization

真空容器广泛应用于航空航天等设备,对某真空容器室进行机构分析,通过SolidWorks进行模型简化,应用ANSYS Workbench进行有限元分析,通过所得到其所受应力及变形情况,找出真空容器的薄弱环节,进而对机构进行适当改进优化。结果发现,通过加加强圈优化之后,有效地减小了容器所受应力及变形,优化了真空容器的局部结构。

The vacuum container has been used extensively in aerospace and other equipments.This thesis shows the model simplification for the well-designed vacuum container room through SolidWorks,and also finite element analysis of simplified model is given by applying ANSYS Workbench.After the press and transformation situation is gotten,optimization of the structure is conducted.The results show that,the stress and deformation of the container can be reduced effectively by the optimization of the Stiffening.
