基于有限元的球面型尾轴承性能研究（英文）
|
摘要
球面型尾轴承是将关节轴承与普通水润滑尾轴承综合而成的一种复合轴承,通过关节轴承自动调心作用可减小由螺旋桨引起的"边缘效应",增大尾轴与尾轴承的接触面积,降低最大接触压力,改善润滑性能。文章应用ANSYS中有限元方法,对球面型尾轴承进行了建模仿真分析和对比,结果表明:球面尾轴承可以增加尾轴与尾轴承的接触面积,使得接触压力分布更加均匀。与普通尾轴承相比,最大接触压力降低22%,刚度也得到减小。文中的有限元仿真可为球面型轴承在船舶轴系上的应用提供理论依据。
Spherical tail bearing is a composite bearing which combines the joint bearing with the ordinary water lubricated tail bearing. The ‘edge effect' caused by the propeller can be reduced by the function of automatic heart adjustment of the joint bearing, and increasing the tail shaft and bearing contact area, reducing the maximum contact pressure and improving lubricating performance. This paper uses the ANSYS finite element method to simulate and analyse the performance of the spherical tail bearing. The results show that the spherical tail can increase the contact area between tail shaft and bearing and make the distribution of contact pressure more uniform. Compared with ordinary tail bearing, the maximum contact pressure decreases by 22 percent, and the stiffness reduces. The finite element simulation in this paper provides a theoretical basis for the application of spherical tail bearing on the ship shafting.
