摘　　要：综合考虑汽车盘式制动器的结构、运动学、热力学等问题,在Matlab中建立制动器时间模型,在ANSYS中建立制动器结构模型和温度场模型,通过数值分析计算进行多学科优化分析和设计。基于iSIGHT集成Matlab和ANSYS,构建制动器多学科设计优化仿真流程及平台,通过二次开发实现参数的提取、输出、更新以及各软件间的数据交换。实际运行结果表明,改善了制动器制动效果,缩短了制动时间并减小了制动器质量。With comprehensive consideration of the structure,kinematics,thermodynamics problems of the automotive disc brake,a time model of brake disk in Matlab,a structure model and a temperature field model of brake disk in ANSYS were built,and the multidisciplinary optimization analysis and design could be made by numerical analysis and calculation.Integrating iSIGHT with Matlab and ANSYS,the platform and simulation processes of multidisciplinary design optimization（MDO） of the disk brake were constructed.In order to achieve the parameters extraction,export and update as well as the data exchanges between the software,the customized development of the software has been made.The result from the platform test demonstrated that the braking effect was improved,the braking time was shortened and the weight of the brake was reduced.
