The Research And Design Of Mechanical Transmission Experiment Platform Based On LabVIEW

The mechanical transmission in the current four kinds of transmission way in a way is the most widely used. With the development of society, the progress of science and technology, mechanical transmission performance also needs to improve in order to adapt to the requirements of the times. Mechanical transmission experiment platform is a comprehensive evaluation of the performance of mechanical transmission experiment platform. It can be in the design of mechanical transmission device or component is to provide a more accurate and comprehensive reference, and can carry out the test, evaluation and Analysis on the performance of the final products. After mastering these reliable data, you can make the product development cycle is shortened and the corresponding product quality can be improved. This method is conducive to product development, many varieties of small batch, and it is also a kind of development trend. So it is very important to research and design of mechanical transmission experiment platform.Virtual instrument(virtual instrument) is a computer based instrument. The combination of computer technology and instrument technology is an important trend in the development of the instrument. The combination of the following two ways: one is the instrument has a corresponding computer function; another is to make computers have the corresponding instrument function. A typical example is the most intelligent instrument and embedded system instrument. The latter is to rely on the existing computer software and hardware resources to achieve the various functions of the instrument. Virtual instrument is now generally refers to a. It is the first with the hardware acquisition, measurement and signal conditioning, through calculation, analysis and processing of signal data related to computer hardware and software resources to achieve, and can make the computer display control panel final processing results in a variety of forms of output in a role similar to the traditional instrument, so as to complete the various measurement functions required.At present in the field of virtual instrument, America national instrument(National Instrument, NI), LabVIEW is a widely used computer language. LabVIEW(Laboratory Virtual Instrument Engineering Workbench,virtual instrument platform) is a traditional line of text and icons using graphical programming language to complete the entire programming, also known as G(Graphics) language, is also a kind of application development environment. The use of its application development efficiency is very high and easy to use, so the research on the application of LabVIEW has its important significance.This paper mainly through the virtual instrument technology research and design of mechanical transmission experiment platform. Introduces the current research status of mechanical transmission test-bed of mechanical structure and its typical control system, and the mechanical transmission experiment platform of the main function modules are analyzed and studied. Then the research and design of the signal acquisition part, through the signal of the sensor are preprocessed and the phase difference, the digital signal processor to complete the algorithm and complete the communication with the host computer, finally completes the experiment operation in LabVIEW.At the completion of the entire system set up after the commissioning of the system, and through a series of mechanical transmission experiment on the whole system of evaluation, detection. The results show that the comprehensive mechanical transmission experiment platform designed in this paper has the ability to complete the evaluation of the performance of mechanical transmission, there are some areas with room for improvement. Based on a digital signal processor based on mechanical transmission experiment platform LabVIEW also explored a new way of measurement and control system for efficient design of real-time, accurate.
