用ANSYS/LS-DYNA软件对平地机落物保护结构进行冲击强度有限元计算,得到了在冲击载荷作用下结构的应力、变形等响应参数,并对比相应技术标准进行了安全性分析,为工程机械FOPS的优化设计提供了结构冲击强度的参考数据。
The ANSYS / LS-DYNA software was used to calculate the impact strength of the ground object protection structure under impact load, and the response parameters of the structure under stress impact and deformation were obtained. The safety of the structure was compared with the corresponding technical standards, The optimized design of the mechanical FOPS provides reference data for the structural impact strength.
