基于Simufact Welding的某型号发动机推力架焊接分析OACSTPCD
Welding Analysis on Thrust Frame of Certain Type Motor Based on Simufact Welding
推力架是固体火箭发动机主推力的传力结构件,一般采用电弧焊接的方式将各组件连接成型,焊接性能的好坏直接影响发动机的正确定位、主推力测量精度及推力架的使用寿命.利用Simufact.Welding软件模拟方法,对推力架组件焊接过程的温度、变形和应力进行分析.结果表明:热源到时焊缝部位发生瞬态变形,且焊缝区域的温度梯度较大,焊缝处冷却后的残余应力大于0235钢的屈服强度.
The thrust frame is main force transmission structure of solid rocket motor.Generally,the components are connected by the way of arc welding.The welding performance directly affects the correct positioning of the motor,the measurement precision of the main force and its working life.In this paper,by using Simufact Welding software,the thrust frame components' temperature,distortion and stress in the welding process is analyzed.Results show that under the eff…查看全部>>
