The Design of Virtual Instrument Based on Mechanical Parameters' Measuring System

Aiming at the problems of single function, comphcated operation and poor expansibility, etc. For the traditional experimental measuring instruments, the writers proposed to develop, on the base of CSY model sensor＇s experimental instrument, a virtual instrument measuring system of mechanical parameters. Measuring principals ＆ methods for relevant mechanical parameters are analyzed in details, and the key techniques of the measuring system such as hardware setting up, software designing and data collecting are explained here. With friendly interface to operators and high ratio of the performance vs price, this developed measuring system could be used to measure some familiar mechanical parameters automatically, like stress, displacement and motor rotating speed, etc.
