Abstract
The new tire unloading machine is used for unloading and turning over the giant radial tire (weighing 6t). During the turning process, due to the huge inertial force of the tire and the collision force between the plywood and the tire, the tire unloading machine bearing is subjected to complex alternating stresses. It is difficult to predict the fatigue life of a bearing. To this end, the paper combines Ncode DesignLife, ADAMS and Workbench numerical analysis platform to predict the fatigue life of tire unloading machine bearings. At the same time, the ISO bearing life standard calculation method is used to evaluate the bearing life and compare the two calculation results. The research results show that the simulation prediction of the bearing life at the lowermost rocker arm of the tire unloader is 2190.56h, and the bearing life of the uppermost guide wheel bearing is 2025.56h. Accordingly, the ISO prediction results are 1717.12h and 1128.44h, which are basically in the same order of magnitude. It shows that the simulation method of bearing life prediction used in the article is reasonable. The research can provide theoretical guidance for the bearing type matching and service life of the giant tire unloader.
