Abstract

To simulate the tread temperature rise of the working subway train in the process of its normal operation and to explore the temperature rise limit of wheel tread during operation, finite element numerical simulation was used in this paper. Based on heat transfer theory and finite element method, a three-dimensional finite element model of the subway wheel was created. According to the braking condition of main line pure air brake, thermal simulation of wheel temperature field was conducted and finally the temp-rising law of the metro wheel was achieved. The results show that the wheel tread temperature first increased rapidly and then slowly decreased until the next brake in a period of "brake, stop, accelerate and coast", with the temperature raised about 110øC in a single brake. At first, the braking heat accumulated in the wheel, with the overall temperature gradually increasing. Then, after several consecutive braking processes, the overall temperature tended to be stable. The tread temperature reached its peak at 3766.5s, with the highest temp reaching 298.9øC during the 31st braking process, not exceeding the limit of temperature rise (400øC).
