Rod Giles, Group Manager CAE & CAD presents at the UK ATC 2019. Royal Enfield has and is undergoing a massive transformation, not only in the sales and manufacturing departments, but also in the way the motorcycles are designed and developed. Leading the way in the development of all new motorcycle platforms is the use of advanced Computer Aided Engineering (CAE) tools. At Royal Enfield we use a wide array of different tools and techniques. The primary tool for model preparation and analysis is Altair Hyperworks. Rather than trying to cover the vast range of analyses carried out, today I will concentrate on some examples where advanced techniques have helped the design process including using smooth particle hydrodynamics (SPH) in explicit analysis to evaluate fuel tank integrity, using NVH director to evaluate and improve transfer path analysis (TPA) to aid the rider comfort, using topology optimisation to reduce mass and improve structural performance of engine and chassis components, and using MotionSolve to understand complex mechanism dynamics.
