Damping Multimode Switching Control of Semiactive Suspension for Vibration Reduction in a Wheel Loader by Tao Wei, Liu Zhiqiang

“…Unlike a traditional semiactive suspension system with continuously adjustable shock absorber, in this work, a novel axle suspension with multiple damping modes is proposed for the wheel loader. The multimode switching damping characteristics are achieved by just changing the discrete statuses of two high-speed switch electromagnetic valves, which makes the damping adjustment simpler and more reliable. …”
