摘要: 针对制动器温度场的研究分析,建立额定起重量32 T的钳盘式制动器三维模型,同时在Workbench中添加制动器材料的各个参数,设置摩擦副间的接触关系,施加制动盘和制动衬片载荷、约束,对制动器制动过程产生的温度场进行仿真。使用LM算法建立包括时间、摩擦因数、制动压力、初始转速的多元非线性数学模型,通过Matlab进行回归分析。最终拟合结果和有限元仿真结果吻合,验证了起重机制动器温度模型的正确性。

Abstract: The temperature of the brake is a key factor affecting brake failure.A three-dimensional model of a caliper disc brake with a rated lifting capacity of32 T is built for the research and analysis of the temperature field of the brake.Meanwhile,various parameters of the brake material,the setting of contact relationships between friction pairs,the application of loads and constraints on the brake disc and brake lining are added to the workbench to simulate the temperature field generated during the braking process of the brake.The LM algorithm is employed to establish a multivariate nonlinear mathematical model based on time,friction coefficient,braking pressure,and initial speed.Regression analysis is made by using Matlab,and our fitting results are basically consistent with finite element simulation,demonstrating the correctness of the crane brake temperature model.
