Simulating researches of impact reaction of vehicle on subgrade in identification possibility aspect

In the paper chosen questions relating to the impact reaction of vehicle on subgrade caused by its movement over road unevenness were described. The problems of vehicles identification during armed conflicts and realizing tasks in frames of peacekeeping missions are introduced. The algorithm of vehicle identification process on the basis of subgrade vibrations caused by its movement was proposed. The model of analysed fragment of road surface worked out using the finite elements method (FEM) was described. The parameters characterizing separate layers of the road were passed. The method of construction loading by the pressure of wheels on road surface was passed as well as the general characteristics of analysed wheeled vehicles. The example results of simulating researches were put the courses of accelerations and velocity of chosen point surface. The method of detection of number vehicle axles on the basis of ground vibration using time – frequency distribution was described. The basic dependences of Wagner –Ville distribution were passed as well. In the paper the examples results of identification of vehicles with differing mass and number of axels were put.
