Design of Stress-Strain Virtual Measurement System for Bionic Plough
The experimental complexities and the interferential factors influencing on signal logging were analyzed for bionic plough worked in the field and laboratory. During design,the anti-jamming methods including hardware and software technology were adopted. Based on hardware of DAQP-12 and QTC-300 data logging sets, and notebook computer, a stress-strain virtual measuring system for bionic plough, which was designed by the graphical programming language DASYLab, was used to measure the horizontal force F acting on the surface of bionic plough by soil. Moreover, the theory of entropy and variance relation was used to analyze the distribution law of the experimental signals after the field experiment,here obtained logA is 1.238. In the end, the experimental results show that measured data conforms to the statistical rule distribution and the error of the whole test system is under 5 percent, so the tress-strain virtual measuring system was stable and credible.
