Ancient Art With the widespread use of computer simulation and rapid to carry out. Detailed practice of this technique is the use of a load bearing direction condition, size, smooth manner, the rotation speed and environment parameters, as well as bearing the main parameters of equivalent output computer through calculus, understanding the life of the bearing can be reached, to evaluate bearing We can design combination. This experimental approach can greatly extend the experiment time, an increase in human and experimental funds, either before the bearing is not manufactured, and afterwards know its effect, it is a quick and hassle free way to experiment. Advanced industrial bearings company SKF, NTN Bearing in research simulation technology to reach the advanced level.

Domestic and foreign development trend

At present, the International Experimental approaches the outer bearing secondary there are four: First, the friction and wear, two, test bench experiments, three laboratory (experimental field) imitation experiment, four, practice conditions driving test. Abroad the several experimental approaches were used, but the purpose is not the same, for example, developing a new product, the first to be done friction and wear. But if the friction and wear way without much change, only the dimensions, by changes in load conditions, you only need to do the bench, imitation or practice run experimentation. Abroad for some key parts of new products (such as wheel bearings, etc.) is extremely harsh assessment, required by the practice of running the experiment, competence allowed to stop supporting the use. Swedish SKF, Japan NTN Bearing earlier research simulation technology, can only substitute bench, imitation or experiment, to extend the product design work, slow down the progress of product development, but also from the actual operation situation of the gap. Today, China's bearing industry has expanded friction and wear, as long as a Luoyang Bearing Research Institute; expanded bench bearing experiment with Luoyang Bearing Research Institute, Shanghai Institute axis, and experimental center in Hangzhou Bearing Wafangdian, Harbin 20 Yu Jiaguo bearing business; you can expand the experiment to mimic Luoyang bearing research Institute, Hangzhou and Luoyang bearing experimental center axis, Xiang-axis and other enterprises. To stop the experiment and practice, bearing consumer business only to be stopped as long as the supporting host companies make this connection requirements, such as railway passenger car wheel bearings and wheel bearings. In short, the international expansion of imitation and experimental aspects of the operation is not common practice, should further expand the scope or practice of the host range of operating conditions for the simulation on the agenda as soon as possible make plenty of hardware and software ready.

Secondary research content and purpose

To stop the simulation, you must first of some representative types of typical products stop bench or imitate experiment to find life with the carrier, as a function of operating conditions between then apply this relationship, after the computer stops bearing design and experimental tasks this is usually only for those extremely important product to stop the experiment. Based on our existing skills, the next decade is a secondary purpose railway vehicles bearing, automotive wheel bearing and high speed grinding machine spindle bearing stop simulation research, and gradually have some simulation conditions.
