Camshaft Design System is a computing programme for the design of different types of valvetrains. Starting from the related acceleration curve of the valve, which is mapped as a spline,the cam profile is calculated using the valve train geometry. Advanced Engine Technology2 Motorsport TechnologyValve Train Design and Calculationfor High-Performance Engines The purpose of the system is thedevelopment of high-qualityvalve acceleration curves thatcomply with the hydrodynamicfringe conditions of the chargecycle while providing an oscilla-tion-attenuated valve train that issubjected to as little dynamicstress as possible. The cam pro-files obtained with this approachare also especially suitable forsubsequent dynamic simulationcalculations, using the multi-body simulation programme Re-curDyn from FunctionBay, be-cause, due to the particular splineapproach, they do not display nu-merical noise in the calculated ac-celeration Design System(CDS) is applied in almost
