Problems solved by technology

However, the weighing results for axle loads cannot be provided
Therefore, when conducting field tests, only the weighing results of the whole vehicle are required, and neither the axle load nor the axle assembly weight can be provided to the user, and the metrological verification institution does not classify the axle load.
However, in terms of transportation and road protection, there are not only restrictions on the weight of the vehicle, but also restrictions on the axle load of the vehicle.
This is because the damage to the road surface caused by the overload of the axle load is even greater, and it will also bring more hidden dangers to the driving safety of the vehicle itself.

Embodiment Construction

[0096] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0097] The invention provides a method for measuring the axle load of a whole-vehicle dynamic automobile balance, especially for the quality measurement of the axle load (axle weight) of an automobile with more than two axles, and belongs to the field of measurement. The method includes: a method of dynamically measuring the axle load (axle weight) of the automobile by using a whole-vehicle dynamic automobile scale;

[0098] The method can be used by manufacturers to measure the quality of additional shafts and shaft groups in the vehicle-type dynamic truck scale and to judge the number of truck axles. This method can also be used in the field test part of the dynamic truck scale of the metrology technical institution, providing the true value of the axle (axle group) of the vehicle with three axles and above and comparing it with the dynamic measurement value of the ...

Abstract

The invention provides an entire-vehicle type dynamic vehicle scale axle load measurement and calibration method and belongs to the field of measurement. The method includes: dynamically measuring vehicle axle load or axle group load by the aid of entire-vehicle type dynamic vehicle scale to acquire dynamic measurement values; performing true value measurement on the vehicle axle load or the axle group load by the aid of a control instrument to acquire conventional true values; comparing the conventional true values with the dynamic measurement values to complete calibration of entire-vehicle type dynamic vehicle scale. With the method, measurement of the entire-vehicle type vehicle scale axle (axle group) and measure calibration capability are effectively improved.

Description

technical field [0001] The invention belongs to the field of metrology, and in particular relates to a vehicle-type dynamic truck scale axle load measurement and verification method. The vehicle-type dynamic truck scale is used to measure the quality of the vehicle and the axle (axle group), especially for the measurement technology. A method for measuring and detecting the weight of a vehicle-type dynamic vehicle balance shaft (axle group) with a control weighing instrument for a mechanism. Background technique [0002] A dynamic truck scale is a kind of automatic weighing instrument with a carrier (including the approach road), which determines the total vehicle mass of the vehicle and (or) the axle load of the vehicle by weighing the moving vehicle. This kind of automatic scale is referred to as a dynamic truck scale for short, including a dynamic truck scale for vehicle weighing and a dynamic truck scale for axle weighing (dynamic axle load balance). Among them, the dyn...
