Increase ride wheeled vehicles due to the continuous damping control in the suspension system

Abstract

One of the promising ways to improve the wheeled vehicles smooth running is the development of dynamic semi-active springing systems, as well as the laws of such systems control. Dynamic control systems in this paper are understood as systems operating at a real-time rate with the current (instantaneous) phase coordinates values. The aim of the work is to develop the laws of optimal control of the wheeled vehicles suspension, providing an increase in the driver and passengers comfort in a wide range of operating conditions. The of the optimal control system algorithm of the level of damping shock absorber suspension wheel machine to improve of the driver and passengers comfort. The proposed algorithm efficiency is proved by simulation methods. It is established that at rectilinear movement on different roads with different speeds, the level of the movement comfort is increased by 8 to 41% when the frequency controlling effect of 15 Hz and 13…59% at the frequency control action of 50 Hz compared to uncontrolled suspension.
