In this paper, the dynamic behavior of the "car + seat + mannequin" system was explored when a car was blasted on a high-explosive munition. The motion of all elements of the dynamic system was modeled in three-dimensional space, taking into account the nonlinear characteristics of the interaction. Variants of detonation of various charges under the front wheel and under the bottom of the car, as well as options in the absence and presence of seat belts and an energy-absorbing element under the seat were considered. In the course of the study, the stresses occurring in various parts of the body and the limiting conditions of survival were determined.

The work was carried out by order of 21 Research Institutes of the RF Ministry of Defense, 2004.

The aim of the work is a comparative analysis of the indicators of stability, controllability and smoothness of the course of cars using mathematical modeling methods. The work was carried out in two stages. At the first stage, the UAZ-3151 was simulated and compared with full-scale tests. At the second stage, off-road cars with various design solutions were modeled.

In the EULER software package, you can simulate various, both standard and special types of tests of automotive equipment, for example: jerk steering, rearrangement, turning 25 meters, turning 35 meters, turning the minimum radius, tilting at the stand, stabilization, acceleration, braking, smooth running on roads with different profiles, reference patency when driving on a deformable ground, moving a moat, a wall or other obstacles and other tests.

In this paper, a study was made of the dynamic characteristics of the smooth running of cars with different types of suspensions. Considered the traditional dependent spring and independent lever suspension of the wheels, a different number of axles of the car. Simulated rectilinear spatial motion of the car along the road with irregularities. Both the same and various irregularities under the right and left wheels were set. The air pressure in the tires and the speed of movement were varied. During the simulation, the characteristics of the dynamic impact in the driver's area were determined.
