OVERVIEW

The course aims to introduce students to product design.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to introduce students to product design, with particular reference to the design process and to design for safety, for manufacturability, for cost, for assembly and for environment.

AIMS AND LEARNING OUTCOMES

The course aims to set out the rules for the design, calculation and representation -according to ISO standards- of typical machine elements (axles and shafts, brakes and joints, chains and belts, bearings, springs, threaded connections, welds, gears). The entire design process is faced according to the Design-for-X and Eco-Sustainable life-cycle guidelines.

The student will be able to schematize simple machine parts, carry out their static and fatigue strenght, choose the most suitable material and suggest the optimal shape according to the DFA and DFM rules, outline the assembly and disassembly methods.

EXAMS

EXAM DESCRIPTION

Written and oral examination. The written test regards the solution of one exercise. The oral examination consists of two questions on theorical aspects. A positive evaluation of the written test is a necessary condition to access the oral examination.

ASSESSMENT METHODS

It will be evaluated the candidate's ability to translate a real mechanism into a simplified representation for the calculation of the stresses and strain given by service loads. In addition, is required that the students can illustrate the architecture of the mechanism by means of hand made drafts, according to ISO rules, both for the assembly steps and the maintenance tasks.
