MR Damper for Aircraft Landing Gear and Future Vehicle Suspension

主讲人 : Prof. Seung-Bok Choi

Design of a new MR damper which can be integrated with aircraft landing gear system. After formulating the governing model of the proposed system, MR damper is designed and manufactured, followed by the field-dependent damping force and controllable domain. Them, the principal performance of the landing gear system; struct efficiency (or sink efficiency) is evaluated with control logics. 

As a second talk, a new type of rotary MR damper which can be applicable to future vehicle suspension with the height limitation is introduced. The design method and operating principle are discussed and the real type of MR damper to be adaptable the purpose-built vehicle suspension is manufactured. Then, the field-dependent damping force is evaluated with respect to the rpm (or angle). Both MR dampers presented in this talk are challenging issues to be resolved in the near future for development of creative and advanced suspension systems to guarantee both ride comfort and safety.

Seung-Bok Choi  is currently working as a leading professor at Mechanical Engineering Department of The State University of New York, Korea (SUNY Korea) located in Incheon Global Campus, Korea, after retirement in 2021 from Inha University where he had worked for 30 years. His main research fields are design and control of various dynamic systems associated with smart materials such as MR Fluid, ER Fluid, SMA and piezoelectric materials. So far, he has published about 700 SCI articles, and 20 books/book chapters. He is still actively serving editorship of 20 international journals including Smart Materials and Structures, Journal of Intelligent Material Systems and Structures, Sensors, and Scientific Report. He has received many distinguished awards from ASME (America Society of Mechanical Engineers), IMehE (Institute of Mechanical Engineers, England), NAEK (The National Academy of Engineering of Korea: regular member) and KAST (Korea Academy of Science and Technology: regular member). It is also remarked that his golf handicap proportionally increasing with respect to the age (average handicap was 74 in Fifties, but now 84).
