The problem of control by a semi-active suspension for increase a ride comfort of a vehicle is considered. On an example of multidimensional mathematical model of the bus, an efficiency of a semi-active suspension with controllable shock absorbers and pneumatic springs is analyzed. Results of computer simulation of movement of the bus with a semi-active suspension on road with a stochastic profile are presented. Calculations have been executed in the program of modelling of dynamics of systems solid and elastic bodies - FRUND. As conclusions it is possible to notice that the semiactive suspension with controlled under offered laws elastic and damper elements allows to depress considerably dynamic ability to loading spring vehicle parts, thereby, raising its stroke ride comfort, without deterioration of parameters influencing stability and movement roadability. Results of numerical experiment and offered laws of controlling can form a basis for creation structurally concerning simple semiactive suspension systems a not demanding for work of a significant amount of power. The semiactive suspension with controlled under offered laws elastic and damper elements allows depressing considerably dynamic ability to loading spring vehicle parts, thereby, raising its stroke ride comfort, without deterioration of parameters influencing stability and movement roadability.
