针对传统工程陶瓷材料粗加工技术成本高、效率低的问题,提出一种利用引弧诱导电爆炸技术加工万法.在Si3N4陶瓷引弧诱导电爆炸加工实验中,对影响温度场分布的主要工艺参数进行实验研究.在简要分析工艺参数对温度场分布影响的基础上,利用正交实验和回归分析的万法建立了温度场预测模型,得出了工艺参数对温度场分布的影响规律.仿真实验结果表明:温度场分布随着加工电流和脉冲宽度的增大而增大,随着喷嘴半径和喷嘴与工件之间的距离的增大而减小,研究结果可以为引弧诱导电爆炸过程的控制提供参考依据,为今后加工多种形状的工件提供参考.%Aiming at traditional engineering ceramics high rough machining costs and low efficiency, arc-induced electricity-detonation processing method is introduced. During Si3N4 ceramic arc-induced electrical explosion processing experiments, carry out the experimental study of the main process parameters affecting the temperature distribution. Based on brief analysis of process parameters on the temperature distribution, use the orthogonal test and regression analysis to establish the temperature field prediction model, and acquire the influence of process parameters on the temperature distribution. Simulation results show that the temperature distribution increases with the increase of the processing of current and pulse width and decreases with the increase of the distance between the nozzle and the work piece and increase of nozzle radius. The results may give a reference basis for process control of the arc induced electrical explosion, and for processing work pieces of various shapes in future.
