摘　　要：为研究地铁刚性接触网滑板和接触线异常磨耗问题,使用环-块式载流摩擦试验机。基于正交试验法,对4种浸金属碳滑板和铜银合金接触线的电滑动磨损问题进行了多参数影响试验。研究了电流强度、滑动速度、法向力和滑板材料等参数对滑板的磨损量和温度的影响。正交试验结果表明,直流电流是影响滑板磨损量和温度的最重要因素,法向力的影响次之,滑动速度的影响最弱。可以通过不同的浸金属碳滑板与铜银接触线的匹配来获得优化的地铁刚性接触网的耐磨性能。In order to study the abnormal wear of contact strips and contact wires of metro rigid pantograph-catenary systems,a block-on-ring type current-carrying friction tester is used.Based on orthogonal test method,multi-parameter influence tests are conducted on four types of electric sliding wear of metal-impregnated carbon materials and copper-silver alloy contact wire.Effects of parameters including electric current strength,sliding speed,normal force,and materials of contact strips on the wear and temperature of the contact strips are investigated.The orthogonal test results show that direct current is the most important factor affecting the wear and temperature of contact strips,normal force the second,and sliding speed the weakest.The optimized wear resistance of metro rigid pantograph-catenary system can be obtained by matching different metal-impregnated carbon strips with the copper-silver contact wire.
