@article{(Open Science Index):https://publications.waset.org/pdf/12688, title = {Continuous and Discontinuous Shock Absorber Control through Skyhook Strategy in Semi-Active Suspension System (4DOF Model)}, author = {A. Shamsi and N. Choupani}, country = {}, institution = {}, abstract = {Active vibration isolation systems are less commonly used than passive systems due to their associated cost and power requirements. In principle, semi-active isolation systems can deliver the versatility, adaptability and higher performance of fully active systems for a fraction of the power consumption. Various semi-active control algorithms have been suggested in the past. This paper studies the 4DOF model of semi-active suspension performance controlled by on–off and continuous skyhook damping control strategy. The frequency and transient responses of model are evaluated in terms of body acceleration, roll angle and tire deflection and are compared with that of a passive damper. The results show that the semi-active system controlled by skyhook strategy always provides better isolation than a conventional passively damped system except at tire natural frequencies.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {2}, number = {5}, year = {2008}, pages = {697 - 701}, ee = {https://publications.waset.org/pdf/12688}, url = {https://publications.waset.org/vol/17}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 17, 2008}, }
