摘　　要：介绍了电脉冲除冰系统的加速度试验,并以峰值加速度为脉冲效果的评判标准,研究了该系统的脉冲性能参数如储能电容器的初始放电电压、电容器的电容量、脉冲线圈与试验蒙皮之间的间距、脉冲线圈的外径以及绕制线圈导线的厚度对脉冲效果的影响。结果表明,放电电压越大,电容量越大,脉冲线圈-试验蒙皮的间距越小,导线厚度越大均会使得峰值加速度增大;但脉冲线圈外径为60 mm的峰值加速度要高于外径为40 mm与80 mm的。该结论可用于指导电脉冲除冰系统的设计。The accelerations test of the electro-impulse de-icing system are introduced. The peak acceleration is developed to evaluate the de-icing impulse effects. The parametric studied are performed to determine the impulse influence. The parameters are the initial discharge voltage of the capacitor unit, the capacitance of the capacitors, the gap between the impulse coil and the testing skin, the diameter of the impulse coil and the thickness of the wire of the impulse coil. The results indicate that the peak acceleration will increase with the discharge voltage, the capacitance of the capacitors and the thickness of the wire. However, the peak acceleration will decrease as the coil-skin gap rises up. Compared with the coils with the diameters 40mm and 80mm respectively, the coil with the diameter 60mm shows the best impulse effect. It is practical to guide the design of the electro-impulse de-icing system using the conclusion.
