Structural Design and Calibration Research on New Flat Dynamic Truck Scale
A new flat type dynamic truck scale with separate weighing surface is designed to address problems of high manufacturing cost and long construction period.The weighing body is composed of weighing platform,connecting plate of weighing platform,sensor,bottom plate and bearing frame.As the core component of the sensor in the scale body,a beam type weighing sensor structure is designed,and the measuring mechanism is described.Through numerical simulation analysis,the resistance strain gauge paste scheme in the sensor is determined,and the layout scheme of the sensor in the scale body is explained.The finite element analysis of the whole structure of the scale body is carried out with ANSYS software,and the total deformation and equivalent stress of the scale body are obtained.Based on the study of the static calibration of the new scale,a calibration optimization method using the weight influence factor to calculate the load value is proposed.Through the numerical simulation of 48 different working conditions,the influence factor of shear strain weight at 48 strain gauge nodes in the scale body is obtained,which provides data support for the calibration of the new scale.
