The Research Of Road Dynamic Weighing System

The development of communication and transportation industry has undoubtedly played an active role in the construction of national economy. However, the overloading of trucking vehicles, which is known as stealthy killers of the highway, remains incessant in despite of repeated prohibition. Harms created by overloading are of manifolds, accelerating road damage, increasing road maintenance cost, leading to substantial run off of taxation and toll fee, bringing about frequent occurrence of traffic accidents, seriously polluting the environment, speeding up vehicle wear-off etc. So that it becomes more and more important to reinforce control over road transportation. Dynamic weighing, i.e. weighing the vehicle on its moving state, with the characteristic of higher efficiency and time-saving, avoids the disturbance to the traffic in the weighing process, as compared with static weighing. Vehicle dynamic weighing is the technical precondition to the modernized and scientific management of reinforcing overloading control and forcing overloading control regulations. And the study of dynamic weighing system is of economic significance and social value in assurance of appropriate use of the roads. For the Vehicle dynamic weighing systems, the weighing accuracy and the speed of the vehicle moving are the most important standard specification. It indicates the technical level of the vehicle dynamic weighing systems. Comparatively the popular one at present is the axle —Axle serious appearance, measures the load of a vehicle's every axle, then through the test system calculate out whole vehicle weight. When the static behavior weighs, the tire of the vehicle acts on steadily on the...
