Finite Element AnalysisThe optimum mechanical design is one that is sufficientlystrong, but no more.• Avoid excess weight• Avoid excess costFor a recent inlet throttle application, this principle wasfundamental to the way in which we developed a newmotorised proportional valve.The intense engine vibration loads become even moresevere with increasing mass.We optimised the design to ensure the valve was strongenough, without over-engineering the design which wouldactually have been counter-productive.We also adjusted the resonant frequency of the valve toavoid catastrophic vibration feedback.23
