摘要
采用虚拟接触载荷法模拟分析管接头中螺纹齿面间的接触现象，在弹塑性小变形条件下，研究了载荷及应力集中系数沿螺纹齿的分布规律，并给出了啮合螺纹齿面的弹塑性应力分布。
It is important in engineering to accurately recognize the dynamic coefficients of plain bearings of large - scale turbines . A new approach to recognize the coefficients on balancing rnachine is prolacoed . The dynamic coeffi- cients of plain bearing of a 50 MW turbine are recognized on a balancing machine of certain factory by using this ap- proach and satisfactory results are obtained .
