Improvement And Development Of Date Analysis System For Metal Belt’s Length Measure Of Automotive Transmission

The automobile industry is in a period of rapid development in China. With the development of technology and the continuous improvement of people’s living standards, more and more family own a car and people are crying for simple and convenient operation. With the advantage of low fuel consumption, low pollution, good power, convenient operation and comfortable driving, CVT becomes as one of the mainstream of the automotive transmission market.As the key component of metal belt continuously variable transmission, the usability of the metal belt’s component determines the working performance of the whole CVT. Now the Bosch company of Germany monopolizes the global market and technology of metal belt component. All of the domestic CVT manufacturers and abroad CVT users rely on their melt belts. Not owning the key technology of melt belt manufacture increases the production cost of domestic CVT manufacturers and restricts the development and security of CVT technology.To realize the production of melt belt, a breakthrough should be made in the field of melt belt length measurement technology. The technology is the key information of Bosch company and there isn’t any method to get the technology information. Moreover there are many differences between we and VDT company in manufacturing technique and measurement method, so we have to depend on ourselves to develop melt belt length measurement technology.Two postgraduates of our research team have done a great job about melt belt length measurement and designed.a set of instrument. There are some disadvantages and shortages in use phase. The work is making improvement on the hardware part of the existing measuring instrument of metal belt’s length and designing the control and analysis for the measuring instrument of metal belt’s length with the purpose of Automation control and data analysis and management.The main contents are as follows:(1) Brief introduction of the research status of metal belt’s length measurement and the purpose and significance of the software design and development for the measuring instrument of metal belt’s length.(2) Brief introduction of the metal belt’s component and matching between the belts in different layers.The description of the composition of measuring instrument of metal belt’s length.(3) Analyze the principle of metal belt’s length measurement and build the mathematical model for the metal belt’s length measurement.(4) The general design of software part for the metal belt’s length measurement.(5) The design and development of various functional modules for software part on the basis of LabVIEW.(6) Test the reliability and stability of the control and analysis system of various functions on a software test platform and analyze the measurement error.
