摘要: 针对我国大功率型重载机车在服役过程中发生的车轮踏面损伤问题,结合安定理论和损伤函数预测方法,从动力学角度展开分析,运用SIMPACK多体动力学仿真软件建立大功率型六轴机车模型。以国家铁路局规定的JM3标准踏面廓形及其不同型号薄轮缘踏面廓形为基本变量,对曲线半径、运行速度等针对性变量开展动力学响应仿真,将其结果分别代入安定图以及损伤函数预测程序来进行损伤计算。通过对不同踏面模型对应工况、车轮轴位等作横向、纵向表征,从多个角度归结了损伤发展规律,认为在部分线路条件下使用JM3薄轮缘型踏面代替其标准踏面能够有效减少车轮损伤的发展,并据此提出了缓解车轮损伤的运行建议和镟修策略。

Abstract: Aiming at the problem of wheel tread damage in the service process of Chinese high-power heavy-duty locomotives, the shakedown theory and wheel damage function prediction methods are adopted to analyze from the perspective of dynamics. The six-axle locomotive model is established by using SIMPACK. Taking the JM3 standard tread and its different types of thin flange tread profiles standardized by the National Railway Administration of People’s Republic of China as the basic variables, the dynamic response simulation is carried out for targeted variables such as curve radius and running speed. Then the results are substituted into the shakedown-map and wheel damage function prediction model to predict the tread damage law. By expressing the results of working conditions and axle positions corresponding to different treads horizontally and vertically, the damage logic is specifically attributed. The result shows that the use of JM3 thin flange tread under some line conditions can effectively reduce the development of wheel damage, and based on this, the operation suggestions and repair strategies for alleviating wheel damage are put forward.

Key words: heavy-duty locomotive, wheel tread damage, damage function, dynamic response, thin flange
