摘　　要：制动器是商用车中的重要安全保障部件。为提高运输车辆的制动安全性,采用领从蹄式结构,设计了一种搭载冲压焊接式制动蹄的新型楔式鼓式制动器。以制动效能与制动鼓体积为目标,对新型鼓式制动器建立优化模型,基于多目标粒子群算法对新型鼓式制动器结构进行优化。引入线性递减权值法,保证算法的准确性,运用惩罚函数法处理算法中的约束问题。基于仿真分析与台架试验相结合的复合分析法,对新型鼓式制动器进行有限元分析与台架试验。结果表明,设计的新型楔式鼓式制动器结构满足设计要求,并优于同规格凸轮式鼓式制动器。Brake is an important safety guarantee component in commercial vehicles.In order to improve the braking safety of transportation vehicles,a new wedge drum brake with stamped-welded brake shoes is designed,it adopts the structure of leading and subordinate shoe brake.Aiming at the braking efficiency and drum volume,the optimization model of the new drum brake is established,and the structure of the new drum brake is optimized based on multi-objective particle swarm optimization algorithm.In order to ensure the accuracy of the algorithm,the linear decreasing weight method is introduced,and using penalty function method to deal with the constraint problem in the algorithm.Based on the composite analysis method of simulation analysis and bench test,the finite element analysis and bench test of the new drum brake are carried out.The results show that the structure of the new wedge drum brake meets the design requirements and is better than the cam drum brake of the same specification.
