Research And Development Of Variable Load And Variable Speed Simualtion Test System For Bearing

The brearings industries emphasis on bearing test more and more along with expanding and improvemention application of bearing products in various sectors of the community and increasing demand on the development of new varieties and improvement of the quality of bearings. Most of the foreign bearings industries develop bearing simulation test standards. It gets more accurate performance parameters of bearing by measuring and calculating from bearing simualtion test which Shorten the development cycle of new products and improve the quality of the product. Howerver, many brearings industries of our community remain focus on the simple life test. It greatly limits the competitiveness of our products in the market that our test results can hardly be recognized by foreign users. It urgently needs to establish a convergence with the international advanced level on the bearing simulation test rules for change which is supported by the bearing simulation test system to research and develop.The paper elaborates the design methods and its ideology of the simulation test system which can be monitored and controlled under load and speed controlling combined with computer and automatic control monitor technology. The system has two parts, including test and control systems and bearings production process management system. It can provide the real-time monitoring and controlling of the test bearing so that the bearing can test in accordance with the system configuration of the speed and load spectrum. Technical staff can analysis the changes of the test bearing parameters from the testing process and sum up the the impact of the changing pattern of the speed and load to the test bearing. Simulation test data stored in real-time management system and the system administrator can also monitor the management system through the simulated testing process. Management system makes the management model of the industries to change fundamental. The preservation of historical data provides a favourable environment for future technical analysis. Friendly and convenient client interface can make the managers facilitate to trackthe process of test.The system of the bearing simulation test opens up new field of bearing test and it provides a pioneering idea and more research data for bearing industries. Variable load and variable speed simualtion test system is a good start of our bearings simulation test. It makes the industry to improve on the research of the bearing test and lays a solid foundation on the broader simulation test for the industry in the future.
