The Study On The Test System Of Automobile Dry Friction Clutch Cover Assembly Parameters Based On VI

In this thesis, We developed a new style test system of automobile diaphragm clutch cover assembly parameters, the purpose of this system is to get the relation curve of release force with displacement and press force with displacement and pressure plate lift with displacement of the diaphragm clutch. And also, the system can show the eigenvalues of these curves.This system is a high-ability semiautomatic test machine including machine, electricity, fluid drive and computer etc. Its mainly functions is continuous data acquisition, show testing curve in real time, high speed data save, data reshow and analysis, multi-curve compare etc. The testing system also has the ability to print testing results if you need them. In the aspect on designing hardware of the system, we develop a sole testing -flat and hydraulic control system. The hydraulic system has lots of merits such as the stable control performance, the rapid response to speed, high alterable drive force etc. So it fits for the necessary and development of the market. At the aspect of software, we adopt virtual instrument (LabVIEW) as our developing flat. And now, VI has already become a mainly methods and artifice to develop complex testing system and instruments, its graphic instrument programmable environments realize the intention of "what you see will be what you want" indeed. Comparing with the common program language, VI is more convenient and simpler,it can shorten the developing periods of the program in large scales.Having finished the testing system, we have had a lot of experiments by it. According to the results and design requirement, we have done a lot of improvements on the system. The results of the experiments show our system has plenty of merits, such as high-precision, stable performance, strong anti-disturb ability and friendly interface. It has met the instrument product require now.
