摘要
通过对接触网零件用紧固件的耐振动性能进行振后扭矩测试和横向振动采用压力环测试应变进行对比分析,提出了合理的接触网零件耐振动性能试验方法.
The vibration-resistant property of fittings of contact network jointed by fasteners was tested by two ways, measuring torque after vibration and testing strain during transversal vibration. A comparative analysis of these two methods has been made and a reasonable test method for measuring the vibration-resistant property of the fittings has also been put forward.
