Tire force can be divided into normal force and tangential force when the vehicle is in tilting condition, the general load cell can't differentiate these two signals accurately. This paper introduces a portable wheel load measuring plate which is characterized by integrating the strain gauge with the upper platform and can be used in tilting condition. In order to decoupling these signals from component of forces, the structure of the upper platform is optimized and analyzed by commercial FEA
