Abstract:

Using the calculation methods of statistical characteristics determining the running smoothness of mobile vehicle, the paper dwells on the calculation of the equivalent coefficient of the linearized resistance of shock absorber with non-symmetrical characteristics. As a result of calculation, it has been established that shows that shock absorbers with non-linear characteristics, dry friction in the springs and the specifical composition of the road’s micro-profile have a significant impact on the low-frequency movement of vehicle on the real road. There is proposed theoretical method, which allows us for calculating the elastic-damping characteristics of the suspension of mobile vehicle, the endurance life and durability of the spring in the design process.
