基于ANSYS的固体火箭发动机珠承喷管摆动接头的有限元分析

FINITE ELEMENT ANALYSIS BASED ON ANSYS OF BALL-SOCKET NOZZLE′S PENDULOUS SOCKET IN SOLID-ROCKET ENGINE

本文应用AN SY S有限元分析软件,完成了对某型号固体火箭发动机珠承喷管摆动接头的有限元分析.得到了该构件在受外部均布载荷和内部集中载荷作用下的位移、应力、应变的有限元解.并对计算结果进行了分析.此计算结果和分析对该摆动接头结构的进一步改进提供了参考依据.

Finite element software of ANSYS has been used for making a finite element analysis of a certain type of ball-socket nozzle＇s pendulous socket in solid-rocket engine. The displacement,stress and strain of the pendulous socket are calculated when the socket is subjected to both outside uniformly distributed load and inside concentrated load. Calculated results are analyzed. The results as well as the analysis provide good reference for further improvement of the pendulous socket＇s structure.
