DESIGN AND DEVELOPMENT OF A 50CC SCOOTER FRAME SUPPORTED BY TESTING AND SIMULATION 2005-32-0100
Modern small capacity motor scooters make high demands on a trendy vehicle design in combination with a customer friendly handling and multifarious storage space. In addition, increasing engine performance characteristics and high requirements on the vehicle weight call for the development of new vehicle frame concepts. Considering lightweight construction and strength durability, the new concepts are also due to fulfill the boundaries of a low cost production. The driving behavior of a scooter is directly influenced by the interaction of the suspension components, the mounting system of the drive unit and the stiffness of the frame. The present publication treats an assessment of different frame types in the 50cc scooter class by tests and simulation with the target to formulate key data regarding the solidness and stiffness characteristics. Based on these data collection a complete new frame concept has been designed and revised by calculation.
