Finite Element Analysis of Thermal Behaviours of a Disk Brake in High-Speed Trains
초록
This paper presents the thermal behaviours of a solid type disk brake for a high-speed train. The thermal behaviours of a brake disk with 50mm thickness shows good performance compared with 45mm thickness of a disk because of a high specific heat capacity and thermal expansion ratio. The FEM results show that the thickness of the d!sk with a same weight of the brake disk should be increased for a good flexibility of the contact thermal problems. Therefore, the ratio between the pad and disk in diameter may be reduced and the thickness of a disk increased.
