Exploration of an Approximate Calculation Method of Brake Disc Thermal Capacity
In the technical conditions of brake disc of urban rail transit braking system,the rotational speed and ventilation conditions of the test bench are different from the conditions of daily running lines.According to the provisions of the technical conditions,an approximate method of calculating heat transfer coefficient is developed,and the calculation of the thermal capacity of brake discs made of different materials is carried out respectively in finite element software,and the difference between the temperatures obtained by the calculation method and the results obtained from bench tests is relatively small,which is of some practicality.
