Background
As automobiles develop, the compactness of the cabin arrangement is increasingly demanding. While the locomotion assembly acts as the heart of the car, its envelope of motion is a central element affecting the compactness of the cabin layout. Therefore, accurate prediction of the displacement of the power assembly in the engine room is a necessary path for adapting to the development of automobiles and improving the compactness of the engine room arrangement. The industry generally predicts the displacement of the powertrain in a forward design, but no mature method/apparatus measures the motion envelope of the powertrain; the existing test system calculates and obtains the motion gesture of a moving object through the measurement of a displacement sensor and the calculation of software. The MPMS system calculates the coordinates of any point by measuring the distance from any point to several fixed points by means of sensors. The stay wire type displacement sensor outputs a voltage signal according to the change of the length of the stay wire, and the relation between the voltage and the distance is obtained through calibration so as to obtain the motion trail of the object to be measured. Usually, the stay wire type sensor is calibrated through a three-coordinate tool, the operation time of a three-coordinate calibration system is long, the measurement calibration deviation is large due to human factors, and the calibration accuracy is influenced. Therefore, an improvement is needed in the existing three-coordinate calibration system for calibrating the pull-wire sensor.
