Quality education Industry, innovation and infrastructure

Academic Year 2018/2019

Learning outcomes

The outcomes of the course are to provide the advanced knowledge, the methods and the tools useful for the correct organization of the mechanical design activities of new or revised products. At the end of the course the students will be able to evaluate the technical and economical impact of the decisions assumed during the designing phase and will be able to reproduce the representation of a complex mechanical system, to define the relationship between the elements, to calculate the constraints, to draw the load diagrams and to compute the maximum tensile state of the components. Furthermore, they will be able to select the most appropriate type of shaft‑hub mechanical connection.

Course contents

Introduction to product design: design set up, design develop and design manage.

The design phases and their best organization

The scheduling of the design phases:

The task clarify

The conceptual design

The detail design

The industrial construction

The simultaneous and concurrent design: time costs and quality of the product design

The QFD (Quality Function Deployment) method

Introduction to mechanical design: design set up, design develop and design manage.

The pressure vessels.

The shaft‑hub couplings: drive fit, taper fit, tongue fit and spline hole/shaft.

Pins and pegs.

Springs and elastic elements.

Teaching methods

The course includes theoretical lectures given with the aid of multimedia systems. The didactic material will be uploaded at the end of the course on the platform “AMSCampus”(http://campus.unibo.it/)

Assessment methods

The exam consists in a written and in an oral test. The written part consists in the solution of three exercises in which, both the conceptual and the numerical results, will be evaluated. The oral part consists in a discussion about the written part and about the theoretical arguments dealt during the lectures.
