Abstract:
In this paper, a novel high-accuracy strain measuring technology based on the method of dual invariable-current, six end connecting and proportional measurement is proposed. The measurement principles, measurement errors analysis and self-calibration technology are described in detail. Lab test data by self-designed multi-channel strain measuring instrument based on the principles and technology is illustrated. The lab test and practical centrifugal load experimentation indicate that the measurement principles and technology are right, and the accuracy, stability, anti-interference and reliability are excellent. The principles and technology for stain measurement are worthwhile in practical engineering applications.
Keywords:strain measurement  dual invariable-current method  six end connecting  propor-tional measurement
