摘要
针对捆绑火箭主接头受力特点提出一种耳片构型方案,根据工程算法进行了初步尺寸设计;基于ANSYS有限元非线性接触算法,设置刚性体和柔性体接触,对刚体添加载荷控制点进行非线性分析:通过有限元仿真分析,证明了较原方案耳片方案不仅安全余度较大,而且结构总重量减轻了32%,具有工程应用前景。
It gives a scheme of main joint connector according the loading character of bundled roceket,and designs the basic parameter based on project Algorithm,based on ANSYS nonlinear contact algorithm,set contact face between rigid and soft body,then set load control point of the rigid body so as to continue simulation analysis.It proved that the safety redundancy is big enungh,and the structure weight reduce for 32%,the blue print of the project is great.
