摘要
针对某型号飞机弹射座椅安装横梁进行有限元建模,进行大变形非线性有限元破坏仿真分析,并与破坏试验结果进行了对比。对比结果表明,仿真结果较好的预估了破坏载荷并反应了结构的破坏形式。
The nonlinear finite element simulation method is adopt to analysis a aircraft ejection seat assemble crossbeam. The analysis results are quite coincident with the results of the destructive test. It shows that the analysis results well predict the destructive load and the destructive form.
