Stress Analysis with Finite Element Method of Large Bearings with Hollow Rollers Used in Wind Turbine System
Journal Title: RECENT - Year 2010, Vol 11, Issue 30
Abstract
In this paper is presented a method for increase the large bearings durability using hollow rollers, demonstrated through computer modelling. Implementation of large bearings with hollow rollers in wind turbine system lead to significant gains in constant power plant operation simplifying management of inertial forces. The mathematical model has been implemented in an algorithm, by which it is possible to study stress distribution for various models of hollow rollers. The analysis with finite element method (FEM) is developed with MD Nastran software.
