The vehicle dynamic balance has static and dynamic functions

The vehicle dynamic balance has static and dynamic functions, and the value of the dynamic part is based on the value of the static part, so the accuracy of the static part is very important for the verification of the dynamic part. Before verification, fujian provincial institute of metrology requires enterprises of weighing apparatus to carry out factory inspection in strict accordance with the standard for the static part of the complete vehicle dynamic balance installed, and then arrange verification after passing the test. All the four weighing equipment enterprises have adopted the load measuring instrument developed by fujian provincial institute of measurement as the standard equipment for full range, full performance debugging and ex-factory inspection. The inspection efficiency is about 2 hours per set, which is highly recognized by enterprises..

Metrology institute of fujian province on the basis of JJG1118-2015 "electronic truck scale (load measuring instrument of weighing method) and JJG 907-2006 the dynamic highway vehicle automatic weighing apparatus verification regulations, for the first time for all the vehicle type dynamic truck scale according to the national technical regulations, carry out the whole range, whole performance verification, solved the weight method is used to test problems, ensure the accuracy of calibration, improve work efficiency, effect is good. The test results show that the static partial error of the vehicle balance is less than 25 kg within the range of (1~25) tons and less than 50 kg within the range of (25~100) tons. Moreover, the weight difference value of the truck with a total weight of about 30 tons is not more than 50 kg. The dynamic weighing accuracy is better than 0.5%. It has truly realized the accuracy and unification of the value of weights and charges of expressways in fujian province.

Fujian expressways co., LTD. Fully affirmed and highly appraised the verification methods and results. According to preliminary statistics, "since the gradual trial of the complete truck scale in fujian province, the weight of the truck with more than 3 shafts has increased by 1.67% year on year.
