Body and interiors components design
Master of science-level of the Bologna process in Automotive Engineering - Torino
Course’s purpose is to give a solid platform of requisite knowledge and skills in body and cockpit design. It will mainly provide notions relating to design specific methodology and materials, according to production technologies of body and cockpit components: graphical representation systems, body, movable parts such as locks, hinges, windows; notions of biomechanics from passive safety tests, restraint systems, dashboard, interior trims, seats, conditioning systems, bumpers, grilles, moldings, spoilers, sill covers, seals, glasses and mirrors, wipers, lights. Furthermore, design and assembling problems will be analysed.
Expected learning outcomes
The student must acquire knowledge concerning setting criteria and design; notions relating to technologies and body/cockpit components materials, with a special attention to comfort, safety and economics. Furthermore, the student will be able to know and critically recognize main architectural solutions and conditioning fundamentals, applied to automotive design, and bonds relating to biomechanical criteria coming from passive safety tests and rating.
