Abstract

Gravity center position is one important index to evaluate the stability of vehicles. A high precision gravity center measure system is proposed in this paper, which can be used in weight and gravity center measuring for large heavy vehicles. Based on a static gravity measuring principle with three measuring points, a hydraulic driven 2-DOF motion platform is developed. By means of a degree-of-freedom control, the platform can realize accurate positioning to construct two intersected planes and work out the three-dimensional coordinates of the vehicle gravity center. Experiments demonstrate that the system's measurement error in weight is less than 0.3%, in Gravity center position measurement is less than 3mm in X and Y direction, and in Z direction is no greater than 5mm.
