【摘要】 本文通过对铜丝球焊接技术中铜形球过程的数值模拟,研究了超细铜丝在微电弧作用下的温度场、速度场以及位移场的变化趋势,从而阐明了铜丝球的形成规律。对位移场的实验验证证明了计算结果的正确性。更多还原

【Abstract】 In this Paper,the temperature file,speed file and the change of displacement file for ultrafine copper wire under a mini-arc has been studied by means of numerical analysis,so the regular pattern of copper wire ball formation has been clarified. The calculating results of displacement file have also been tested and verified.It has been shown that the calculating results are correct.更多还原
