Williams FW33 – Solving rear wing vibration issues


The unusual and innovative rear suspension assemble and in particular the fact that the upper wishbones are attached directly onto the wing’s pillar and the lack of any support of the beam wing onto the rear crash structure caused excessive vibration to the wing , something totally unwanted because it dramatically reduces aero efficiency of the car . To decrease wing’s lateral movement and provide extra stiffness Williams supported the beam wing  onto the pillar ( in yellow ) via a connector .Furthermore in Melbourne ,  to totally overcome any vibration issue , the endplates were mounted onto the diffuser roof via single metallic pillars (lower illustration ,red arrow)  . In Williams case the endplate support have no aero contribution as happens in Mc Laren case .
