| 摘 要： | 考虑波箔轴承中波箔与接触面间摩擦力的影响，得出了计算波箔局部结构刚度的简化公式，并分析了影响波箔轴承结构刚度的参数。结果表明：波箔局部刚度并不相等，而是从固定端到自由端逐渐减小；波箔轴承结构刚度随波箔弹性模量、波纹厚度、非固定端波纹高度和接触面摩擦因数的增大而增大；随波纹半长度和节距的减小而增大；且节距对结构刚度的影响比其它参数要大。

| Abstract: | A simplified formula was developed to calculate the local structural stiffness of each bump of the bump foil with the consideration of frictions between bump foil and its contact surfaces, and the influences of different parameters on the structural stiffness were analyzed. Results show that the values of local structural stiffness of bump foils decrease from the fix-end to the free-end, rather than being uniform; the structural stiffness of bump foil bearing increases with the accretion of bump elastic modulus, thickness and non-fixed bump height, fraction coefficients of contacting surfaces while increases with the decrease of bump half length and pitch. The influence of bump pitch is more prominence than other parameters. |
