The Design Of Brake Shoes Stack Adjuster's Tiring Test

Brake shoes stack adjuster is an important part of act-enable of trains and it is used to adjust the distance between Zhawa and Wheels in pair. With the development of the railroad, the capability and the stability of the act-enable parts of these equipments are faces baptism. At the same time, testing the biometry of the equipment faces higher needs than before too. For no indexes of tire-age before, with the revving up of the train, this problem becomes serious little by little. In order to test the tire-age, a machine of examination of it is used. It is called brake shoes stack adjuster tire test machine.In order to satisfy the requirement of brake shoes stack adjuster' tire test, this machine's part is designed, the characteristic of reliability and utmost working state are considered for the design of mechanical part. And it's relatively easy to change the damageable parts. Use Delphi as a developing environment, Measurement and control software are designed to automatically control the machine and record the testing value. Watcher computer and control computer can also communicate through it. The design uses the pc-camera as the tool to get the abundance information, uses the technique of Serial communication, technique of Video for Windows and theories of digital image processing, uses Visual C++ as the developing environment and exploits this new set for testing and controlling automatically. The design involves four models and makes the automation of test-control reality. It also uses some theories of digital image processing to deal with the information of the test in that time and to record the unwonted status messages. The design could offer helps to the unmanned automation of the test-control.Because it's very difficult to fix a sensor on this machine, a pc-camera is selected to inspect the working condition of the machine. It not only can improve reliability and capability test but also can continue running for several month. The whole system utilized advantages of the advanced test & control system sufficiently, enhanced automatic degree of the performance test system., moreover reduced influence to test data conduced by man-made factors, improved test's veracity and reliability.
