FEA ANALYSIS OF THE SHIELD MACHINE MAIN BEARING UNDER RADIAL FORCE

摘要：

For three-row of roller shield machine main bearing, which is in large dimension and has large number of rolling elements, it’s difficult to build an intact finity model to simulate. By using ANSYS software, one half of bearing and a single roll are respectively established under the action of the radial force. The contact stress distribution of a bearing and the position of the maximum load roller are confirmed by analysis of the half bearing model. Based on the finite element analysis of a single roller, the contact stress of a single roller is calculated. A single roller analysis results are close to the solution of hertz theory. This research makes the first step for continuous study on loading the moment and combined load.
