| Abstract: | Based on analyzing the design principle of integrated weighing board style tyre weight, the scheme that the load cell of weigh-in-motion system is designed by using spoke-board type weighing sensor is proposed. The process of using finite element software to deal with sensor organ modeling, meshing, loading and boundary condition is expatiated. According to the strain distributing rule of sensor organ, the slices disposal and location are found, and the complete bridge differential circuit is composed to measure the precise weight of tyre load which may act on the different areas of weighing board. Dynamic response experiment is done to analyze the characteristic of the frequency response. |
