摘要:
［目的］为满足200 km/h以上的隧道内刚性接触网系统弓网接触性能要求，对刚性接触网汇流排进行结构参数优化设计和性能检验研究。［方法］针对汇流排的材料属性和结构特点，提出了一种新型的大惯性矩汇流排结构，并建立了刚性接触网仿真模型，开展在200 km/h高速条件下现有汇流排和新型汇流排的静力性能检验、弓网动力性能仿真与实车试验研究。［结果及结论］新型汇流排相比现役汇流排具有更优异的高速性能。使用新型汇流排，采用不同跨距，在200 km/h和250 km/h速度下进行弓网动力学仿真研究并在160 km/h和200 km/h速度下开展现场试验，结果表明新型汇流排能适应较高的跨距，最高跨距可达9 m。
Abstracts:
［Objective］ To meet PC (pantograph-catenary) contact performance requirements of the rigid catenary system in tunnels with the speed exceeding 200 km/h, the structural parameter optimization design and performance test of the rigid catenary busbar are studied. ［Method］ Considering the material properties and structural characteristics of the busbar, a new type of large inertia moment busbar structure is proposed, and a rigid catenary simulation model is established. Under 200 km/h high-speed condition, the static performance test of existing and new busbars, PC dynamic performance simulation and actual vehicle test are carried out. ［Result & Conclusion］ Test results indicate that the new busbar demonstrates superior high-speed performance compared to the current one. Using a new type of busbar with different spans, dynamic simulations of the PC system are carried out at speeds of 200 km/h and 250 km/h, with on-site tests conducted at speeds of 160 km/h and 200 km/h. The results show that the new busbar can accommodate larger spans, with a maximum span reaching 9 meters.
