| 摘 要： | 针对深空探测采样容器的特殊要求,进行爆炸焊接严实密封技术研究。利用非线性动力学软件进行铝质柱形容器爆炸焊接数值模拟,得到各种焊接初始参数的影响规律,确定较佳焊接初始参数及容器结构尺寸,并进行实验验证。实验结果表明:外盖角度为7°时,1mm壁厚外盖配4mm壁厚内圆柱或2mm壁厚外盖配6mm壁厚内圆柱,配以较合适炸药厚度,密实焊接效果较理想。研究结果为深空探测采样容器结构设计提供了较好的参考。

| Abstract: | Aiming at special demands of specimen container for outer space exploration, explosive welding tight sealing technology is studied. Numerical simulations of cylindrical aluminum container explosive welding are implemented by using the nonlinear dynamics software. Influence of several important initial parameters on explosive welding are obtained, and the optimum welding parameters and container dimensions are decided. Verified experiments are carried out and the experimental results show that when the weldi... |
