According to the requirements of the national metrological verification regulations of JJG 907-2006 "Dynamic Road Vehicle Automatic Weighing Instrument", when the dynamic axle load meter can be used as the integrated control weighing instrument to determine the true value of the uniaxial load agreement of the two-axis rigid reference vehicle by the static weighing instrument, First, it is subjected to a static loading test. When the static test meets the requirements, each single axis of the two-axis rigid reference vehicle is weighed in turn, and each uniaxial load is recorded. When both single axes are weighed, the sum of the two uniaxial loads, ie the total mass of the vehicle, can be calculated. According to the method, the vehicle is properly loaded and unloaded, so that the axle load can cover the weighing range of the weighing instrument to determine the static reference uniaxial load, and the agreed true value of the total vehicle weight of the reference vehicle under different load conditions is calculated.

In order to improve the safety factor and work efficiency of the weight loading, and to adapt to the use rate of most products, a dynamic axle loader with a small bearing area is used as a reference, and a special raft is designed through the idea and method of stacking blocks. The code platform supports the bracket and two flat weights of different appearances to achieve the superposition, which can effectively reduce the total stack height to reduce the safety hazard, and realize the full-scale static loading requirement.
According to the requirements of 6.3.1 of JJG 907-2006, the total design quality of the special weight platform bearing bracket should meet the requirements of the dynamic axle weight scale in the initial zero adjustment range not greater than 20% of the Zui scale (Max). In the initial zero state, the weighbridge can still meet the starting value display zero point, without affecting the accuracy of the weight indication after adding and unloading.

Note: Dynamic axle weight is a gauge that dynamically weighs a moving vehicle. It determines the total mass of the vehicle by weighing the individual axes or groups of the vehicle and automatically accumulating the weighing results of the axes (or groups of axes).
