The Research And Development Of Online Motor Test-bed Used In Vehicle

Motors of the vehicle parts which are one of the key parts are widely used on the car,so its performance will be strictly required. Traditional detecting methods are backward, low precision and low. It is difficult to adapt to the modern industrial production. This text bases on the item of automobile glass lifts electric motor production lines from an automobile parts manufacturers, developed a micro motor testing system and a performance test-bed .This new type of equipment which can meet the testing requirements can fundamentally overcome the disadvantages of traditional methods.This thesis mostly does the following research work:First, an analysis of the level of domestic automotive electron I industry, which is the base of automotive test and the main direct of automotive industry, is made. Our stand-in put upon electronics.Second, a review is attempted to make a review on Chinese standards for glass regulation riser motor, which are applied across China in the whole industry for automobile manufacture. Therefore the review provides the test installation of glass regulation riser, and these standards are doubtlessly what the test should meet. Moreover, this paper is trying to establish a plan according to QC/T636-2000 and attention is paid totes four parameters in this test installation: the speed and torque of motor idling, load, plug load current, the noise and vibration power. Third, a comprehensive online motor vehicle-testing system is designed; the standard parameters are created to determine whether the motor is good. The methods will be found to reduce the noise.At the same time, the circuit of the testing bed must assure the working precision and reliability. The circuits of the testing bed include all the sensors select, the sensors regulator circuit design, the filter circuit design, the digital display watch design, the A/D card design, the relay module design.We take Visual C++ 6.0 as development instrument, which utilize design philosophy of object oriented programming(OOP).We developed the entire software by VC++ 6.0 under Windows operating system. Its friendly graphic user interface, flexible operating manner, and powerful data processing function. Clicking start test key-press on control interface, system will read the data in specific port of A/D card by run related function of VC++ and realize the data collecting. At the same time, system can send order to specific port of A/D card to control the peripheral equipment. The software will process collected data and show corresponding curve on screen, produce and print the test report.At last, a test on glass regulation riser motor in was made based on this test installation. All four quantities for five times and after system debugging are tested, which proves that this test installation system meets all request and an ideal outcome is achieved.
