This article investigates the effect of frame compliance and rider mobility on the scooter stability. Particular attention is given to the wobble mode, because it may easily become unstable in the vehicle speed range. This article includes a synthetic discussion of previous works, presents a new mathematical model, and discusses the results of both numerical and experimental analyses of the vehicle stability by varying the vehicle characteristics and motion conditions. The mathematical model… Expand

Numerical and experimental investigation of passive rider effects on motorcycle weave
Despite the importance of rider passive response to the lateral dynamics of motorcycles, there is very little literature on the subject. Even more uncommon are works that consider rider passiveExpand
Analysis of the Phenomena Causing Weave and Wobble in Two-Wheelers
TLDR
This work aims to ascertain, in depth, the physical phenomena that stand behind the influence of fork bending compliance on the wobble mode and behind the velocity dependence of the weave damping behaviour. Expand
Dynamic stability of an aerodynamically efficient motorcycle
Motorcycles exhibit two potentially dangerous oscillatory modes known as ‘wobble’ and ‘weave’. The former is reminiscent of supermarket castor shimmy, while the latter is a low frequencyExpand
Experimental and numerical analysis of rider motion in weave conditions
Motorcycle dynamics is characterised by the presence of modes of vibration that may become unstable and lead to dangerous conditions. In particular, the weave mode shows large yaw and rollExpand
