摘　　要：讨论了弓网受流原理和受流质量评价体系,通过Simulink仿真手段,对弓网接触压力和受流质量之间的关系进行了研究,提出滚动弓头受电弓设想,并依据接触电阻理论、冲量理论、摩擦磨损理论,分析滚动弓头对弓网性能的提升原理。The principle of pantograph-catenary system and the quality evaluation system of current collection were discussed in this paper. Based on the simulation study of the relation between the quality of current collection and the contact pressure by using the software simulink, a new idea of rolling collector head was proposed. The principle of the current collection performance enhance by use of the new rolling collection head is also analyzed based on the contact resistance theory, the friction and wear theory and the impulse theory.
