基于ABAQUS的膜片联轴器动力学特性分析
尤文, 柳晖
上海师范大学 信息与机电工程学院, 上海 200234
摘要:
针对旋转试验机的动力系统所使用的弹性膜片联轴器,在考虑联轴器不对中的情况,利用有限元软件对膜片受力情况进行模拟分析,得出了平行不对中和交角不对中情况下膜片的最大接触应力以及分布情况,利用有限元软件和转子动力学原理计算出联轴器的固有频率,并和制造商处得到的不对中量和最大转速数据进行对比,得出计算的应力和共振频率已经达到了极限值,验证了模型的正确性和计算方法的可靠性.
关键词:  膜片联轴器  不对中  有限元  固有频率

College of Information, Mechanical and Electrical Engineering, Shanghai Normal University, Shanghai 200234, China
Abstract:
Base on the diaphragm coupling of driving system of a rotation testing machine,FEA software ABAQUS is used to simulate the force which the coupling gets when it is working,to obtain the stress and stain during the coupling with axial misalignment and degree misalignment and to find where the maximal stress is as well as its distribution.Then the nature frequency of the coupling is calculated by use of finite element software and rotor dynamics and compared with the date of misalignment and maximum speed from the manufacture,which verifies the correctness of the model and the reliability of the calculation method.
Key words:  diaphragm coupling  misalignment  finite element  natural frequency
