Flexible cam profile synthesis method using smoothing spline curves

摘要: This paper describes a synthesis method of designing flexible cam profiles by using smoothing spline curves. Our approach simultaneously considers displacement, velocity and acceleration rather than displacement alone in the design process. The inherent characteristic ensures smoothness designed proposed method. essential difference between other existing approaches is that our allows designers to refine motion local modifications while still satisfying profile discrete constraints. Particularly, can control not only level but also shape curves for better kinematical dynamic properties. Examples show obtained provide solutions some problems automotive engine valve trains.
