The Active Suspension experiment teaches cutting-edge technology that has brought a new generation of vehicles to life. Active suspension technology is used in the automotive industry to continuously control the vertical movement of the vehicle wheel using an actively-controlled actuator placed on the suspension axis. Similar technologies have also been used in train bogies to improve the curving behavior of the train and the decreased acceleration perceived by the passenger.
Active Suspension
The Active Suspension consists of three masses that along stainless steel shafts using linear bearings and is supported by a set of springs. The upper mass (blue) represents the vehicle body supported above the suspension, the middle mass (red) corresponds to one of the vehicle’s tires, and the bottom (silver) mass simulates the road. The upper mass is connected to a high-quality DC motor through a capstan to emulate an active suspension system that can dynamically compensate for the motions introduced by the road. The lower plate is driven by a powerful DC motor connected to a lead screw and cable transmission system.
