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 Technology2Motorsport 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 all ar-eas of Engine development: carseries development, large dieselengines and all areas of motorracing, as well as by system sup-pliers, in research and conventional design sooncomes up against limiting factors,special design tools have been de-veloped for valve trains in high-speed ArchitectureThe flexibility and adaptability ofCDS is due to the modular struc-ture of the programme, which ismade possible b
