Theoretical research of impact of the changed elastic and damping parameters of vehicle tyres and loading on the wheels breakaway time from the cobblestone road

Abstract

The article is devoted to the theoretical research of impact of the changed tyre stiffness and damping on the wheels breakaway time from the cobblestone road when driving at different speeds. The spacial four-support five-mass mathematical model of GAZ 322132 two-axle vehicle dynamics has been developed considering the breakaway. There are the results of the mathematical model theoretical research in the form of dependences of the front left wheel breakaway time from different combinations of tyre stiffness and damping at different vehicle speeds.
