某型发射筒动力接管部位应力的有限元法分析

Stress Analysis on the LCPP by FEM

基于有限元理论，建立某型发射筒动力接管部位的弹性力学模型，计算不同工质内压作用下动力接管部位的应力分布情况，探讨分析动力接管部位产生局部应力集中的主要原因及分布规律。

Based on FEM （ Finite Element Method）, the elastic mechanics model of the bonded LCPP （launch Canister and Power Piping）is built and solved under different internal pressure. Then each reason for stress concentration is analyzed and the rules of stress distribution are put forward.
