Semi-Active Twin-accumulator Suspension System 2002-01-0985

{In this paper, semi-active twin-accumulator suspension system is studied theoretically using a quarter vehicle model. The bounce motion for the sprung mass and vertical degree of freedom for unsprung mass are considered. The linear optimal control theory is used to drive the full state feedback. This paper suggests a simple solution for eliminating discomfort by using semi-active twin-accumulator suspension system, which involves modifications to the twin-accumulator suspension system and conventional passive suspension system without neither excessive cost nor complexity. Moreover, the paper provides a theoretical evaluation for using semi-active twin-accumulator suspension system suggested, and compares the results obtained to those given by the twin-accumulator system and the conventional passive suspension system. As a result the semi-active twin-accumulator suspension system gives worthwhile improvements when compared to the conventional passive suspension system, and twin-accumulator suspension.}
