摘要:
应用三维设计软件pro/e建立了符合300 km/h高速动车组实际尺寸的制动盘模型,通过pro/e与ANSYS之间的接口将模型导入ANSYS软件平台,建立了紧急制动工况下高速动车组制动盘的热-结构耦合计算模型.并充分考虑了制动盘材料参数随温度变化的影响以及制动盘与闸片之间的热流耦合的影响,应用ANSYS软件强大的非线性多物理场处理功能,得出了制动盘温度场和应力场的分布规律.制动盘在t=66 s时达到最高温度815℃,t=90 s时达到最大应力760 MPa.
Abstract:
Using the three-dimensional design software pro/e, a brake disc model that conforms to the actual size of a 300 km/h high-speed EMU is established, and the model is imported into the ANSYS software platform through the interface between pro/e and ANSYS, and the thermal-structure coupling calculation model of the brake disc of a high-speed EMU under emergency braking conditions is established. The distribution of the temperature field and stress field of the brake disc was obtained by applying the powerful nonlinear multiphysics processing function of ANSYS software to fully consider the influence of the material parameters of the brake disc with the change of temperature and temperature and the influence of heat flow coupling between the brake disc and the brake pad. The brake disc reaches a maximum temperature of 66 °C at t=815 s and a maximum stress of 90 MPa at t=760 s.
