摘　　要：大型回转支承是风力发电机、建筑机械等重型机械中至关重要的大型回转连接件,国家标准中要求其使用寿命不低于20年。因此在设计选用时应对其承载能力、疲劳寿命等进行有效的校核分析,以确保其使用时的可靠性。论文结合工程实际,根据回转支承实际工作时的受载情况,对其承载能力、疲劳寿命、摩擦力矩、接触变形等计算分析过程进行了研究,同时运用Matlab/GUI平台开发出相应的仿真系统,并编译出了exe可执行文件,使其能够广泛应用于回转支承相关行业。A large size slewing bearing is an important rolling rotational connection in heavy machinery such as wind turbines and construction machines, and the fatigue life of a slewing bearing is required to be more than 20 years. Therefore, to ensure the high reliability of a slewing bearing, the load capacity, fatigue life and so forth have to be analyzed when designing or choosing a slewing bearing. It researched the carrying capacity, fatigue life, driving torque and contact deformation of slewing bearing in engineering practice, and developed a CAD system based on the Matlab/GUI platform The system contains all necessary calculations and provides a friendly interface for users. Furthermore, by using the compiler module, an executable file （ ＊.exe ） can be created, which is supposed to be widely used in slewing bearings and relevant industries.
