The development of Virtual Instrument Technology provides a new idea for mechanical engineering measurement. Software system of Virtual Instrument offers a serial of instrument panels which could be called. The relations between different modules would be completed by developer. In this way, measurement system could be made up flexibly. Moreover, for testing technicians, they hope that the constructing of measurement system is only related to the theory and technology of testing rather than the complicated job of software programming. This is also the requirement of the contemporary science research and the flexibility experiment system of college laboratory. Therefore, it has important practical and theoretical meaning to develop the rapidly bination measurement & control experimental systems by modularization methods. In accordance with the requirement of the course experiment of Mechanical Engineering Measurement, the frame design of the hardware platform which is based on the mechanical platform with five degrees of freedom, the multifunction DAQ card, and several kinds of sensors & clamps is discussed in this p
