A STUDY OF ACTIVE SUSPENSIONS FOR HEAVY VEHICLES

An active suspension may be described as one which can exert or generate a force independent of the direction and velocity of the wheel or suspension unit. Micro-electronic sensing devices can be used to monitor vehicle and road conditions, and according to these inputs an electronic control unit can determine the appropriate force values to be applied at the suspension's various wheel locations. The paper summarizes the following: 1) characteristics and performance of current heavy vehicle suspensions, 2) characteristics and advantages of active suspensions, and 3) the potential for active suspensions to reduce road loading, operating costs and rollover-related accidents.
