摘　　要：对后驱动单轮周盘式制动器进行了研究,探究周盘式制动器的生热机理,建立热-结构耦合仿真分析,预测制动器可能出现的失效形式。在试验台架上进行了连续制动实验,为新型制动器提供理论和实践的支撑。通过定时记录不同测量点的温度变化,结合台架实验可以看出,随着循环制动的进行,每次制动周期的最高温度基本上呈梯度式增加,而且实验和仿真结果基本吻合,实验和有限元仿真的最大误差为8.29℃,验证了有限元分析的可靠性,为之后的生产设计和整车实验提供理论依据和实验支撑。The rear-drive single-wheel circum-disc brake is studied, the heat generation mechanism of the circum-disc brake is explored, the thermal-structure coupling simulation analysis is established, and the possible failure modes of the brake are predicted.Continuous braking experiments are carried out on the test bench to provide theoretical and practical support for the new brake.Through timing records temperature changes of different measurement point, the bench test, you can see that as you progress through the loop brake, brake every time period basically is the highest temperature gradient increased, and the experiment and the simulation result was consistent, experiment and finite element simulation of the maximum error is 8.29 ℃,the reliability of the finite element analysis, It provides theoretical basis and experimental support for subsequent production design and vehicle test.
