一种新型液体动压轴承动态特性的分析计算

Analysis and Computation on Dynamic Characteristics of a New Style Hydrodynamic Journal Bearing

在研究产品设计的三维实体造型理论及有限元仿真技术的基础上 ,应用SUN工作站上的I DEAS软件完成了一种新型的液体动压轴承的三维变量化造型设计及有限元仿真 ,对动压轴承进行了静态、动态力学性能的分析 ,计算出油膜的八个动态特性系数 ,并与其它同类轴承进行了比较 。

This thesis completes 3D variational modeling design and Finite Element Simulation of a new style hydrodynamic bearing by I DEAS software,based on studying 3D solid modeling theory and Finite Element Simulation technology carefully and deeply.This thesis analyses the static and dynamic characteristics of bearing,computed the eight dynamic coefficients of oil,analyses the characteristics of this bearing after comparing with the other bearings
