The train brake disc structure strength analysis
Abstract: With the rapid development of high-speed trains, constantly improve its speed, on
the train braking performance requirements are also increasing, and the traditional way brake -
brake shoe brake has been difficult to meet the needs of the high-speed train braking. Compared
with brake shoe brake, the disc type brake are characterized by their smooth braking, low noise,
good heat dissipation performance advantages, has become the development trend of modern
high-speed, heavy-duty train braking. At first, this paper designed a speed of 200 km/h
high-speed train brake disc, the three-dimensional finite element analysis model is established,
through the thermal analysis function of finite element software ABAQUS, the brake disc is
discussed in the braking process, any instantaneous moment of the distribution of temperature
field and thermal stress field for high-speed trains in braking process, the change of the surface
temperature of the brake disc and the changes of the axial stress at different positions of the
plate, provide theoretical reference for the structure improvement of brake disc.
Keywords: brake disc; thermal stress; finite element method; ABAQUS

1.1 研究背景及意义
目前高速列车的制动已成为国内外研究的热门课题， 我国以及欧美等发达国家都在加
快发展高速重载列车以便提高列车的通过质量，提升线路的通过能力。列车制动方式有多
种，常用的制动系统有两种类型：闸瓦制动和盘型制动。闸瓦制动是通过闸瓦和铁轨之间
的压摩擦来实施的； 盘形制动是通过作用在轮盘面或固定在轴上的轴盘面的摩擦来实施制
