The article is devoted to research of a vehicle ride comfort, equipped the suspension system with combined control of springing and damping elements. The spatial mathematical model of a vehicle which meets the requirements of adequacy to real object was developed. The results of the computer simulation of movement of the vehicle with controllable and passive suspension systems on stochastic microprofile are presented. It can be concluded that the spatial multi-mass model is satisfactory close to a real object and can be used for further calculations. Having analyzed simulation results we can state significant increase of ride comfort of a vehicle equipped with a controlled suspension system. Decrease of vertical acceleration of a cabin in a place where a driver sits amounted to 40% in average that can be considered as a limit value for this type of controlled suspension systems. It can be noted that a suspension system with combined control of springing and damping elements can be considered as rather effective in terms of decreasing load of vehicle spring-mounted parts that along with low power consumption makes it rather competitive. The shown research results and control laws for springing and damping elements can be used as a basis for development of relatively simple controlled suspension systems.
