摘    要:以制动器强度和刚度作为约束条件,采用计算机辅助集成技术对领从蹄式制动器中的制动蹄进行轻量化设计研究。使用ABAQUS软件对领从蹄式制动器进行有限元分析,得到制动蹄的应力分布情况,并提取分析过程中制动鼓受到的摩擦力矩。通过ISIGHT软件集成CATIA和ABAQUS对制动蹄进行参数优化,对优化结果再次使用ABAQUS进行进一步分析,以提高分析精度,确定制动蹄最终的优化尺寸。研究结果表明:由分析得到的摩擦力矩与实验的制动力矩比较可知基于ABAQUS的分析步骤与方法正确可行。使用轻量化方法对制动蹄进行轻量化设计的效果较好,质量降低17.87%,应力仅增加2.86%,既实现了制动蹄的轻量化,又保证了制动蹄的强度和刚度。研究结果可为同类产品的有限元分析以及轻量化设计提供参考。

Abstract: Computer aided technology for brake shoe’s lightweight study with brake’s strength and stiffness as constraints was used. The leading shoe and trailing shoe brake were analyzed by ABAQUS software, and the stress distribution of brake shoes and the friction torque of drum were obtained. Brake shoe was optimized by ISIGHT software integrated CATIA and ABAQUS. To improve the accuracy of analysis and ensure brake shoe’s optimization size, ABAQUS was used to analyze the optimization results again. The results show that the ABAQUS analysis steps and methods are correct and feasible by comparing the friction torque and the barking torque gotten by experiment. This lightweight method can make a good effect on brake shoe, i.e. the mass decreases by 17.87%, and stress only increases by 2.86%. This research work realizes the lightweight design for brake shoe and guarantees its strength and stiffness, It can provide technical information and reference for similar products finite element analysis and lightweight design.
