| 摘 要： | 利用ADAMS对便携式轴重仪的动态称重系统建模并验证模型的可靠性.首先根据实际称重传感器结构和建模原理进行建模,控制单一变量仿真称重过程,得到不同速度、重量下的仿真称重数据.然后利用相同参数的便携称重系统实现实际测量,并与相同条件下仿真结果比较分析.实验结果表明,在30 km/h以下,仿真数值与实测数值相差不超过5％,验证了动态称重模型可靠性,为仿真数据取代现场实测提供可行性,为今后称重信号补偿奠定了理论基础.

| Abstract: | A finite element model of weigh-in-motion (WIM) system for portable axle load scales is built by using ADAMS software based on the actual structure of weighing sensor and modeling principle,simulating the weighting process with a single variable controlled and getting the simulation data from different speeds and weight.Actual data from a portable weigh-in-motion system with the same variables are used to compare with simulation data.The result shows that the error value between numerical simulation and actual data is within 5% at speeds slower than 30 km/h,with the reliability of the model being proved,and the simulation data can be proceessed directly. |
