车辆动态称重仪使用现状及其轴重信号分析

The Use Situation of Vehicle Weigh-in-motion Device and Analysing on Signal of Axle Load

叙述了我国超限重运输的规定和管理现状,给出了车辆动态轴荷信号形态,讨论了对轴(轮)荷信号进行分析的几种方法,结合研究课题重点分析了自调整遗忘因子的快速时变系统参数辨识算法,并给出了辨识仿真算例。

In this paper, the criterion and management situation concerning the overload transportation in the country are described. The vehicle's dynamic axle load signal graphers are proposed. The analysis methods of the axle load signal are discussed. The parameters identifying arithmetic, which is defined with a autoregulation forgetling factor and used in a fast time-varying system, is presented, meanwhile a simulation example is given.
