摘要
针对悬挂式车辆中间车钩在列车动态调试过程中发生异响问题,本文从车辆运行工况、车钩结构组成、尺寸公差设计等方面分析了车钩可能出现异响的原因,并逐条分析验证.针对车钩出现异响的原因,提出结构优化方案,经过验证,方案优化后的结构完美解决了中间车钩的异响问题,提高了车辆运行过程中的可靠性和乘坐舒适性.
Abstract
According to the abnormal sound problem of middle coupler mounted on the monorail vehicles dur-ing the test process,this paper analyze the possible causes from the aspects of operation condition,structure composition of coupler,dimension tolerance design and others,and analyze and verify the possible causes item by item.According to the causes analysis result of the abnormal sound problem,this paper give a structural optimi-zation scheme,which is proved to be a perfect solution to the abnormal sound problem of middle coupler,and im-proves the reliability and comfort of the vehicle during running.
