Designing of Kids Train

Abstract: Designing a Kids Train body and Chassis, where Body of a train plays an important role as it should be attractive, fun, educational, comfortable and safer for the kids. and the chassis should be able to withstand sufficient load and able to accommodate steering, battery, seating, motor, axles and bumper at all sides which is developed for SB international AB.A literature study is carried out to review various designs body of train and chassis, latest innovations and advanced materials used to manufacture the same. The various types of forces and stresses commonly acting on chassis structures are analyzed and their effects on the vehicle is understood and different types of train design is studied in order to make an attractive train for the kids by using Waterfall method to understand the concepts in designing a Train body. The pro-con analysis is conducted to evaluate merits and demerits of each alternative type of body of a train and the material to manufacture it. The most essential  design criteria are derived from the QFD (Quality function deployment) which then acts as important guidelines during the actual design process.Structural chassis frame is designed as per the design criteria with little modification and designing a body of a train using the CAD software CATIAV5R20 and the structural stability of the same is tested and analyzed using Inspire (solid thinking) software.
