摘要：高速动车组极大地加快了经济发展，在法国和德国先后研制出高速铁路后，世界各国都了解到高速铁路的重要性，包括日本、美国、中国等国家也先后开始研制高速铁路。近几年来，高速铁路的发展速度惊人，因此对于高速动车组的研究不断深入，其中就包括对动车组通过性能的研究[1]。改变轮轨接触的几何关系会影响列车的曲线通过能力，影响列车运行的安全性，因此研究轮轨接触问题有利于提高列车的曲线通过能力和安全性，是十分必要的。本文主要研究特定条件下的轮轨通过性能，包括不同踏面类型，轨道以及速度等因素对轮轨通过性能的影响。通过SIMPACK来创建高速动车组的动力学模型，利用仿真计算数据来说明特定条件下的轮轨通过性能。研究在不同踏面和不同的通过速度的情况下动车组的动力学性能，以便于今后更好的在特定条件下选择更加利于列车通过的踏面类型和行驶速度，提高安全性，舒适性。无论如何。在高速铁路飞速发展的同时，我们不能因为提高了速度而忽视了高速动车组的通过性及安全性的问题，对于这方面的研究应该不断深入，更加全面。71005

Analysis of Wheel / Rail Through Performance under Specific Conditions

Abstract:High-speed EMU has greatly accelerated the economic development, in France and Germany has developed high-speed railway, the world has learned the importance of high-speed railway, including Japan, the United States, China and other countries have also started to develop high-speed railway. In recent years, the rapid development of high-speed railway is amazing, so the research on high-speed EMU deepening, including the EMU through the performance of the study. Changing the geometric relationship between the wheel and rail contact will affect the curve passing capacity of the train and the safety of the train operation. Therefore, it is necessary to study the problem of the wheel and rail contact to improve the curve passing capacity and safety of the train. In this paper, we mainly study the influence of wheel-rail performance under specific conditions, including different tread type, orbital shape and velocity. This paper considers the dynamic model of EMU, SIMPACK is used to create the dynamic model of high-speed EMU. The simulation results show that the wheel-rail performance under certain conditions can be used to study the dynamic performance of EMU in different treads and different passing speeds Of the dynamic performance, in order to better in the future under certain conditions to choose more conducive to the train through the tread type and driving speed, improve safety and comfort. Anyway，in the rapid development of high-speed railway at the same time, we can not blindly in order to improve the speed and ignore the high-speed EMU through the sexual and security issues, for this research should be in-depth and more comprehensive.
