Numerical research of the high-speed military vehicle track

The paper presents the problem of the use of tracked combat vehicles. Due to the high speed of their moving, as well as the nature of the terrain and obstacles traversed, the forces in track links reach significant values. Therefore, an attempt was made to determine the value of dynamic forces acting on tank during overcoming selected terrain obstacles. For this purpose, a numerical model of the T-72 tank was developed. With its use, simulation studies were carried out, including overcoming typical obstacles. In all tests, the ground was treated as rigid. During the tests, the accelerations of the tank, the traction force and the values of forces in the selected joints of the track were determined.
