基于HyperWorks的某迫击炮座钣结构优化
|
摘要
为了在保证可靠刚度和强度的基础上减轻某迫击炮座钣的质量,对其进行结构优化和轻量化设计。通过Hyper Works有限元软件对迫击炮座钣安装在土壤工况下的刚度和强度进行仿真计算,采用寻找主要受力路径并修改应力集中区域结构的方法,对座钣进行了结构拓扑优化,改进了座钣结构。在此基础上,对座钣的主钣和驻臼进行了尺寸优化,对优化前后的座钣强度、位移和质量进行了对比,结果表明,优化后的座钣不仅减轻了质量,还提高了强度。
To reduce the quality of a mortar base plate on the basis of ensuring reliable stiffness and strength,the structural optimization and lightweight design were carried out. The HyperWorks finite element software was used to simulate the stiffness and strength of mortar base plate under soil conditions.The method of searching the main stress path and modifying the stress concentration area structure was used to optimize the structure topology of base plate,and the structure was improved. On this basis,the size optimization of the main plate and socket of base plate was carried out by using the size optimization method. The finite element analysis was carried out to compare the plate before and after the optimization.The results of finite element analysis show that the strength of the optimized base plate greatly improves,and the weight of the base plate reduces.
