摘要
对某型导弹发射车的联接耳座进行了有限元分析,找到在发射车发射架起降过程中,耳座处于最大压力下时,上下耳座的危险处,通过耳座的应力和应变云图得出应力分布情况,并将有限元仿真结果与理论计算值进行了比较,说明了理论计算存在的缺陷,为保障武器系统的安全,有限元仿真很有必要。通过仿真分析,可以看出上下耳座中应力较大部分的位置,即危险点的位置,为耳座的损伤识别和无损检测提供一定的支撑,为后续耳座的的优化设计提供理论参考。
The finite element analysis of the connecting auricular socket of a missile launcher was carried out.The dangerous place pf the upper and lower auricular socket were found out under the maximum pressure of the Auricular Socke during the lifting and lowering of the launching frame of the the launch vehicle.The stress distribution can be seen through the stress and strain nephogram of the auricular socket.The finite element simulation results were compared with the theoretical calculation results,which shows the defects of the theoretical calculation.In order to ensure the safety of weapon system,finite element simulation is necessary.Through the simulation analysis,the location of the dangerous point was found,which provided a certain support for the damage identification and nondestructive testing of the auricular socket and provided a theoretical reference for the subsequent optimization design of the auricular socket.
