Background
With the development of automobiles, the compactness of the cabin layout is more and more demanding. The dynamic assembly is used as the heart of the automobile, and the motion envelope of the dynamic assembly is a core element influencing 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 arrangement of the engine room. The industry typically predicts the displacement of the powertrain in a forward design, but there is no mature method/apparatus to measure the motion envelope of the powertrain; the existing test system calculates and obtains the motion attitude of a moving object by measuring through a displacement sensor and matching with software. The MPMS system measures the distance from any point to a plurality of fixed points through a sensor to measure the coordinate of any point. 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 detected. Generally, the calibration of the pull-wire type sensor needs to be carried out through a three-coordinate tool, the three-coordinate calibration system has long operation time, the measurement calibration deviation is greatly influenced by human factors, and the calibration accuracy is influenced. Therefore, the existing three-coordinate calibration system for calibrating the pull-wire sensor needs to be improved.
