Mechanical engineering

The object of the study is the damper developed by the authors that reduces parasitic oscillations of the core of the vehicle by automatically increasing the resistance forces in its mains. The damper is installed in the suspension of any vehicle or freight cars. In order to test the effectiveness of the installation effect of the damper for smooth running and maintaining the key characteristics of the car (performance and fuel economy). We have performed simulations of the damper design developed. We have drawn conclusions about reducing parasitic oscillations of the core of the car with the help of the damper on the basis of the frequency response. Studies have confirmed the effectiveness of the damper, since due to its dissipation characteristics a reduction of up to 60 % in the average amplitude range is achieved.
