摘要
静强度分析是机械设计过程中的重要组成部分,而有限元法则是分析机械结构静强度的重要方法。简单介绍了有限元法的概念和基本思想、静强度分析方法,重点介绍了应用ANSYS软件的命令流方式对铝合金空调机壳体结构进行建模,分别在6种冲击载荷工况下对铝合金空调机壳体结构进行静强度分析,发现铝合金空调机壳体结构的薄弱位置。根据计算结果可知,铝合金空调机壳体结构在6种冲击载荷工况下的各个最大应力都在许用应力的范围内,满足静强度的设计要求。
Static strength analysis is an important part in the mechanical design process,and finite element method is an important method for static strength analysis of mechanical structures.The concept of finite element method,the basic idea of finite element method and static strength analysis are introduced.Command stream is used to build the FEA model of aluminum alloy air-conditioner housing structure.Six impact loads of the FEA model are analyzed in static strength analysis to find the weak positions of the aluminum alloy air-conditioner housing structure.The calculation results meet the requirements in six impact loads of the FEA model.
