A stabilizer bar in a suspension system is useful for preventing excessive rolls in vehicle maneuvers like cornering. Stabilizer bars are supported with bushings by either a frame or a subframe. To prevent the axial movement of the stabilizer bar within the bushing, features like add on collars, upset rings, grippy flats etc. are used on the stabilizer bar. At Visteon Corporation, several new stabilizer bar - bushing systems are developed where such axial movement is prevented by the use of compressive force. Relative merits of different stabilizer bar - bushing systems are compared in terms of roll stiffness and maximum stress on the bar through the use of finite elements.
