中文摘要：

鼓式制动器在制动过程中,其温度场、应力场和磨损存在强烈的耦合现象。本文中首先将有限元技术和广义Archard磨损模型相结合,利用应力-磨损耦合分析方法,模拟了鼓式制动器的磨合过程;然后基于热-应力-磨损耦合算法模拟了制动器在单次制动过程中的热-应力-磨损耦合过程,展现了制动器的温度场、接触压力场和磨损的演变规律及其相互作用。最后,利用鼓式制动器台架试验对仿真结果进行验证,试验结果和仿真结果吻合良好。

英文摘要：

The strong coupling effects between temperature field, stress field and wear of drum brake in braking process are studied in this paper. Firstly, by combining finite element technique and generalized Archard wear model, with stress-wear coupling analysis method adopted, the running-in process of drum brake is simulated. Then, based on coupled heat-stress-wear algorithm, a single braking process is simulated to show the evolution rules of and the interaction between these three fields. Finally, a bench test is conducted for verification, with a result well agreeing with the simulated one.
