Design of vehicle weighing module based on support vector machine

Vehicle weighing module is the core part of vehicle weighing system. The working principle, flow and implementing scheme of vehicle weighing module were presented. 3D model of the vehicle frame was established by Pro/Engineer. In ANSYS, necessary simplification of this model was done and load was applied to the frame according to the actual situations; then the strain sensitive point was found and the relation between strain and load was obtained. The algorithm of weighing was set up based on support vector machines (SVM) and its feasibility and correctness in different conditions was verified by using cross-validation method.
