Analysis of Temperature Rise Characteristics of Brakes in Electric Buses on Long Down Slopes
摘要
Abstract
To enhance the safety and energy utilization efficiency of electric buses on long down slopes,a Zhongtong electric bus model is taken for research.Through theoretical analysis and simulation experiments,the temperature rise characteristics of the brake system and the key influencing factors are discussed.A downslope dynamics model of the vehicle and a thermal conduction model of the brake are established.The ANSYS finite element analysis software is used to simulate the temperature rise under different slopes and different initial speeds.The results show that the down slope is the core factor affecting the temperature rise rate.For every 2%increase in slope,the time to reach the peak temperature is reduced with an average of 49.8%while the initial speed has a comparatively small impact on the peak temperature rise with a variation of less than 10%.The research provides a scientific basis for the optimization of braking strategies and system design,helping improve driving safety and energy utilization efficiency.关键词
