随着重载快速的实施,P60钢轨鱼鳞伤和剥离掉块更加突出,发展更加迅速.本文通过对津浦、沪宁、沪杭等繁忙干线上的钢轨鱼鳞伤和剥离掉块情况的现场调查,总结了钢轨鱼鳞伤及剥离掉块发生发展规律及主要基本特征,运用赫兹接触理论、轮轨磨擦学理论和轮轨耦合动力学理论,分析了钢轨鱼鳞伤和剥离掉块的成因,提出了减缓和整治钢轨鱼鳞伤和剥离掉块的措施.
With the rapid implementation of heavy load, P60 rail scale injury and peeled off the block more prominent, more rapid development.In this paper, Jinpu, Shanghai-Nanjing, Shanghai and Hangzhou and other busy rail line rail scale injury and peeling off the scene of the situation, The development rules and basic characteristics of rail scale injury and peeled off block were summarized. The causes of rail scale injury and peeled off block were analyzed with Hertzian contact theory, wheel-rail friction theory and wheel-rail coupling dynamics theory. And remediation rail scale injury and stripping off the block measures.
