| 摘 要： | 从最基本的动力学方程出发,通过一维简化研究了某承受特定冲击载荷的支架的动力学响应问题.通过理论公式与有限元方法相结合提出了在冲击载荷下的支架动强度评估方法,可以方便地用于支架在特定冲击载荷作用下的动强度估算,并推广应用到类似的结构设计当中.

| Abstract: | The bracket dynamic response under the particular shock load based on the orthogonal relation between models are researched,and a method with dynamic equations and finite element method combined is presented to evaluate the bracket's dynamic strength.It has been verified that the method is applicable to the other similar structures. |
