对北京地铁14号线弓网性能进行了分析研究。介绍了弓网测量系统的工作原理,结合测试数据,对接触力分布、接触力最值、弓头振动加速度、受电弓与接触网燃弧现象、定位点处接触网的高度和拉出值等测试结果分别进行了分析。研究表明:列车在加速区段和通过锚段关节、线岔、分段绝缘器及刚柔过渡区域时,弓头振动加速度变大,接触力突变,局部线路弓头振动加速度有突变现象。
The performance of bow net of Beijing Subway Line 14 is analyzed. The working principle of bow net measurement system was introduced. Combining with the test data, the distribution of contact force, the maximum value of contact force, the vibration acceleration of bow head, the arcing phenomenon of pantograph and catenary, the height of the catenary at the locating point and the pullout value The test results were analyzed separately. The results show that the acceleration of bow head becomes larger and the contact force suddenly changes when the train accelerates and passes through the joints, branches, segmented insulators and rigid-flexible regions of the anchor segment. The sudden acceleration of the bow line of local lines changes suddenly.
