| 摘 要： | 制动系统是快速货车的关键技术之一,制动盘是制动系统中承受机械及热负荷的主要部件。通过160km/h快速货车制动计算,确定了紧急制动过程中制动盘的边界条件,并通过ANSYS建立有限元分析模型,得到制动过程中制动盘温度及应力分布。通过分析计算,确定了在160km/h快速货车上每轴制动盘的数量。

| Abstract: | Braking system is one of the key parts in a rapid speed wagon,and brake disc bears huge amount of heat and mechanical pressure.Via relative parameters of the 160 km/h freight in emergency brake and brake calculation,the way how to apply the brake force in an emergency brake process is improved.Through emulation by ANSYS,the feature of temperature field and stress field is obtained.The number of discs in each alxe in the 160 km/h high-speed freight is confirmed by detailed analysis. |
