| Abstract: | Basic principle of the on line detection upon linear strain of mechanical components based on equi-spaced magnetic lattice has been introduced. The processing of detected signal and method of waveform transformation have been advanced. Let the detection of linear strain of mechanical components be transformed into the measurement upon the sustained time of high-low level of waveform in the detected signal, and the mathematical relationship between measured value of time and linear strain of components was derived. Thus new technology and method for realizing non-contacting real-timed on line quantitative detection on linear strain of mechanical components were provided. |
