It's lacking to consider the static axle's load only in evaluating road damage by vehicle, and on the other hand, DLC (Dynamic load Coefficient) isn't sufficient also, which is used often.

The technique of dynamic load identification can be used to identify unknown dynamic load in the case of knowing matrix of coefficient and dynamic response being measured already.

The dynamic characteristics of the system has been studied. The influence of the mesh stiffness of each stage to the dynamic load sharing coefficient has been discussed.
