| 摘要: |
| 通过对国内外现有受电弓性能的分析，提出了应开发主动受电弓。为改善弓网动态特性，使受电弓对于接触网具有良好的跟随性，减少离线和拉弧，必须减少弓网间接触力的波动，使之在一定的范围内变化。提出在受电弓集电头和底座上安装执行机构，通过传感器返回弓网接触力，与估计力的差值作为控制的输入去控制受电子的位移。同时也介绍了受电弓主动控制的思想，模型及弓网接触力的受力方案。弓网间受车一般设定为力作用在受电弓集电头上，与执行机构配合作用去按制受电弓，达到主动控制的目的。 |

| Abstract: |
| By analyzing the performances of current pantographs,it is suggested to develop active pantograph.In order to improve the catenary-pantograph dynamic characteristics,i.e.let the pantograph follow the catenary to reduce pantograph stray and arcing,the pantograph-catenary contact force should be stable and change within a certain range.It is suggested to fix actuators on pantograph collecting head and base.The pantograph-catenary contact force is fed back by the sensor,the difference of estimated and measured contact forces is used to control the pantograph's displacement .The con-cept ,model and strategy of pantograph active control are introduced.The pantograph-catenary contact force is exerted on pantograph collecting head,and combined with the actuator it is used to control pantograph. |
