| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 97 === Go-kart (or called KARTING), is the one of the formula cars internationally. For purebred vehicles which designs for the competition. Go-kart (KARTING) origins from US, is originally re-equips by farmers in the agricultural leisure the farm machinery equipment, rear-drive to Europe, researches and develops by the European country it the improvement, and promotes to world, therefore Go-kart is in fashion in Europe more than the US and Canada. This kind of vehicles itself volume is not big, the Go-kart’s length is approximately 180cm, the width is 140cm, the weight probably position in 200~230kg, the vehicle race leaves ground 3cm.
This research mainly coordinates experiment the Taguchi method with the computer assistance project analysis technology to design deliberated how utilizes the design cost which the shortest time most saves to discover in front of the small vehicle race optimization of structure the bumper bar.
This article first does hit experiment an aluminum nature hollow circular pipe by the drop hammer impact experiment, accelerates course of the gauging its acceleration; And photographs its aluminum nature hollow circular pipe after the high-speed camera to hit the aberration condition. Again analyzes and compares the hit experiment and the value analogue result by the commercial limited ultimate analysis software LS-DYNA simulation hit computation. By the dynamic experimental result and the value simulation confirmation, the simulation part and the experimental result tallies approximately. Applies mechanically the value simulation to confirm computer of assistance project analysis way the result; Before and possibly will affect the bumper bar secure parameter using the Taguchi method to list specially; If front bumper bar long, width size, cross section (cross-section) contour, material quality attribute (metal material and compound materials); And causes its matching to present the optimization condition.
This article tries to provide the designer a set of conformability optimization design method; Reduceing generally time and the cost which must spend in the research and development design stage. To expect and provide its commercialization the automobile correlation industry manufacture production’s reference.
