A Quarter-Car Experimental Analysis of Alternative Semiactive Control Methods

摘要: The performance of three semiactive control policies, including the well-known skyhook and two others that are referred to as “groundhook” “hybrid” control, studied experimentally. experiments use a single suspension apparatus is commonly “quarter-car” rig, magnetorheological damper built tuned for purpose this study. Upon describing mathematics policies construction quarter-car results series with each policy presented. transmissibility plots test confirm features policy, discussed in past analytical studies. indicate can significantly reduce sprung mass, compared passive dampers. Similarly, groundhook substantially reduces unsprung mass transmissibility. For vehicle applications, reducing oft...
