The following by using the finite element analysis method of electromagnet and the friction ring in the downhill path each time the temperature field is analyzed, and verified by the test on the accuracy of the analysis model and method.
When the temperature is high to a certain extent, due to mechanical, physical and chemical factors in three aspects of the role of the brake friction coefficient decrease, decline of braking effect, this phenomenon is known as the decline of braking efficiency of the brake thermal, thermal decline is one of the important indexes of evaluating the performance of actuator system.
When the car brakes on downhill or high speed continuous use in emergency brake, the brake component temperature will rise sharply.
The electromagnet is a key part of the electromagnetic brake, it has a great influence on the performance of stability and reliability of the electromagnetic brake.
