摘　　要：对不同接触状态下电触头材料静熔焊力进行了测试。应用威布尔分布对静熔焊力数据进行处理,获得了95%置信区间对应的关系曲线并按照5%概率进行取值,得到不同接触状态下静熔焊力最大值数据。分析了电触头材料在不同接触状态下塑性变形对静熔焊力影响,指出了电触头材料降低静熔焊力的发展方向。The static welding force of contact material under different contact condition was recorded andanalyzed with Weibull distribution. The value of 5% in Weibull curve was selected to represent the maximum valueof static welding force. The influence of contact material plastic deformation on static welding force under differentcontact condition was discussed and suggestions were given for reducing the static welding force of contact material.
