摘　　要：采用ANSYS有限元软件,建立了胶接钢制旋转圆盘在离心力作用下的振动模型,研究了胶粘剂的弹性模量对65Mn钢圆盘胶接结构固有频率和应力分布的影响。结果表明,随着胶粘剂弹性模量的增加,结构的固有频率提高,胶层中心线上各应力分量的值也增大。使用弹性模量较低的胶粘剂制备盘状结构,对降低其固有频率和胶层中的应力有利。The effect of elastic modulus of adhesives on the natural frequency and stress distribution of adhesively bonded steel disc structure was studied using finite element method. A vibration model of rotating disc under centrifugal force was created with ANSYS software. The results obtained from numerical simulation show that the natural frequency of steel disc is increased with the elastic modulus of adhesive. The value of stress along the mid-bondline is also increased with the elastic modulus of adhesive. Lower elastic modulus is beneficial for the adhesively bonded steel disc structure to decrease its natural frequency and stress in adhesive layer.
