using gear mechanism in vehicle Suspension as a method of altering Suspension Characteristic
Journal of Vibration and Control, 2015Co-Authors: Ming Foong Soong, Rahizar Ramli, Wan Nor Liza Binti Wan MahadiAbstract:A passive vehicle Suspension has constant spring and damper properties that compromise either ride or road holding ability, depending on whether the Suspension is designed to be hard or soft. This study examines the implementation of a gear mechanism in a vehicle Suspension system to alter its Suspension Characteristic while keeping the same spring and damper properties. In the study, a rack-and-pinion mechanism was used to modify the Suspension force which acted between the sprung and unsprung masses of a quarter vehicle model. The system with proposed Suspension layout was modeled mathematically and solved to obtain the vehicle response due to step excitation for various gear ratios. Results indicated that the use of such a mechanism was capable of changing the equivalent Suspension force of the system. It was noted that different gear ratios would amplify or reduce the equivalent Suspension force, hence emulating a harder or softer Suspension setting compared to that of the original Suspension. Additio...

hierarchical optimisation on scissor seat Suspension Characteristic and structure
Vehicle System Dynamics, 2016Co-Authors: Chunlei Wang, Xinjie Zhang, Konghui Guo, Yi YangAbstract:ABSTRACTScissor seat Suspension has been applied widely to attenuate the cab vibrations of commercial vehicles, while its design generally needs a trade-off between the seat acceleration and Suspension travel, which creates a typical optimisation issue. A complexity for this issue is that the optimal dynamics parameters are not easy to approach solutions fast and unequivocally. Hence, the hierarchical optimisation on scissor seat Suspension Characteristic and structure is proposed, providing a top-down methodology with the globally optimal and fast convergent solutions to compromise these design contradictions. In details, a Characteristic-oriented non-parametric dynamics model of the scissor seat Suspension is formulated firstly via databases, describing its vertical dynamics accurately. Then, the ideal vertical stiffness-damping Characteristic is cascaded via the Characteristic-oriented model, and the structure parameters are optimised in accordance with a structure-oriented multi-body dynamics model of...
