摘　　要：在电热化学炮中,计算脉冲电流在铜柱测压器上产生的感应涡流和电磁力,对可能影响膛压测量精度的电磁力与火药气体压力进行比较分析,根据分析结果认为,电热化学发射试验中,输入到等离子体发生器的脉冲电流不会影响铜柱测压器对最大膛压的测量。Induced eddy currents and electromagnetic forces in copper cylinder pressure gauges are computed in an electrothermal-chemical gun.The electromagnetic force,which might have an impact on the accuracy of pressure measurement,is compared with gas pressure generated by propellants.Simulation results show that pulse current inputted to the plasma generator does not affect the pressure measurement by using copper cylinder in the chamber.
