北京地铁14号线弓网动态相互作用性能研究

Study of Pantograph Catenary Dynamic Interaction Performance for Beijing Metro Line 14

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 pantograph catenary performance of Beijing metro line 14 was analyzed and studied. Pantograph catenary working principle of the measurement system was introduced, and combined with the test data, the distribution of contact force, contact force’s the most value, pantograph head vibration acceleration, pantograph and catenary arc phenomenon, the height of the catenary anchor point and the pulling value test results were analyzed respectively. Research showed that： when the train was in accelerating section and through the anchor segment joints, line bifurcation, section insulator and soft transition area, vibration acceleration of pantograph head turned great, and contact pressure and the pantograph head vibration acceleration of local line had mutation phenomenon.
