摘要
对某型动车组齿轮箱接地装置外盖安装螺栓开展重复使用的可行性研究,通过螺纹表面质量、机械性能、抗腐蚀性能、防松性能和疲劳性能等方面对比分析新螺栓和已使用60万公里数后螺栓的性能变化,评估已使用60万公里数后螺栓再使用的技术可靠性。
A feasibility study was carried out on the re-use of bolts for the gear box grounding device outer cover of a certain type of bullet train.The performance of new bolts and bolts used after 600,000 km were compared and analyzed through the aspects of thread surface quality,mechanical properties,corrosion resistance,anti-loosening properties and fatigue properties,and the technical reliability of bolts used after 600,000 km was evaluated.
