摘　　要：通过对厚度相同的双螺母防松联接拧紧过程进行的载荷分析可知,主、副螺母的受力不同;结合施加工作载荷的情况下对螺栓受力的影响,得出两个不同厚度螺母在防松联接中的合理使用位置,为达到螺栓的预期防松效果提供最佳方法。After analyzing the loading of two nuts with identical thickness in double-nut anti-loosening connection, different force between the main nut and the vice nut were obtained. According to different force of the nuts in loading mode, the reasonable positions of two nuts with different thickness in anti-loosening connection were obtained, which offered an optimum method for achieving anticipated anti-loosening effect.
