英文摘要：

Aiming at the special, poor, and high precision measurement requirements of the working environment, a non-contact type magnetic piezoelectric displacement sensor was developed, based on magnets repel and piezoelectric effect.The general scheme of the displacement sensor was determined and its mechanical structure and circuit was designed.An experiment platform on a medium-sized truck was set, a non linear regression analysis was made to the theoretical value and the calibration curve of the sensor was fit.On this basis,experiment was conducted with the result that the relative error is less than 0.5%.h proves that the displacement sensor can measure the displacement in the special environment with high precision, and it meets the requirements of industrial application.
