This paper describes the process of product planning for a F-125 machine, which is an on-road racing car equiped with an 125cc motorcycle engine. To determine the product specification, our former machines, competitive machines, regulations of the AARK F-125 Grand Prix were investigated, and requests of racers were collected and reflected. In the early design stage, an ergonomics approach was introduced for design of a cockpit. A driver was measured and modeled using the human module of CATIA V.5. This manequine model was used to analyze driver's view range, size of seat, positions of steering wheel and pedals. In addition, a PDM system was established on the basis of TeamPDM, and used for management of product data generated mainly using CATIA V.5. Introduction of a PDM system facilitated sharing product and design information systematically between product developers.

In automobile exhaust system, internal pulsating pressure and shell vibration greatly affect the exhaust noise and the surface radiated noise. This noise is emitted from the tailpipe outlet and the muffler outer wall due to the pulsation of the exhaust gas pressure. This paper describes an analytical study of these characteristics as influenced by exhaust system structure. An exhaust system simulator was used for generating the pressure pulsation. The relationship between pulsating pressure and exhaust noise was analyzed. The relationship between shell vibration and surface radiated noise was also identified by finding FRF.<br/>
