摘要/Abstract

摘要： 热疲劳裂纹是导致列车制动盘损伤乃至失效的主要原因。此项研究将虚拟裂纹闭合技术与有限元二次开发相结合，通过建立带有预制裂纹的制动盘有限元仿真分析模型，研究了制动盘裂纹面的接触状态、裂纹张开闭合状态以及裂纹扩展行为。结果表明，制动盘表面裂纹的存在对制动过程中的压应力场没有显著影响，但会影响残余拉应力场的分布，并在裂纹前缘出现应力集中现象。在制动过程中，制动盘裂纹面间的法向接触压力从摩擦面沿着裂纹深度方向逐层变化，且表层和深层的法向接触压力相对大小会发生改变；制动盘裂纹面间的法向相对位移则从裂纹中心点呈贝壳状向裂纹前缘扩散，并随着冷却过程的进行张开位移逐渐增加至最大值。随着裂纹尺寸的增加，制动盘裂纹的张开时刻逐渐延后且裂纹形貌趋于扁平化。

Abstract: The propagation of thermal fatigue crack is the main reason of railway brake disc damage and even failure. In order to study the crack opening and closing state, contact state of crack surface and crack propagation behavior, the virtual crack closure technique and finite element secondary development are combined to analyze the finite element model of the brake disc with prefabricated cracks. The results show that the presence of surface crack of the brake disc has no significant effect on the compressive stress field during braking, but it affects the distribution of residual tensile stress field, and the stress concentration phenomenon appears at the crack front. During the braking process, the normal contact pressure between the crack surfaces of the brake disc changes layer by layer along the crack depth direction from the friction surface, and the relative magnitude of the normal contact pressure between the surface and the deep changes. The normal relative displacement between the crack surfaces of the brake disc diffuses from the crack center to the crack front in a shell shape, and gradually increases to the maximum with the cooling process. With the crack propagation, the crack opening time of the brake disc gradually delays and the crack appearance tends to flatten.

Key words: brake disc, thermal fatigue crack, virtual crack closure, crack propagation, finite element analysis
