OVERVIEW

The course provides the basic principles for the design of common-use machine elements.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to lead students to master the methodologies and tools, analytical and numerical, for the study of the tension/deformation in solids and structures and the structural design criteria of the main mechanical parts (static strenght, in presence of creep, against brittle fracture, fatigue and peak load). Furthermore, students will be able to tackle the eco-compatible design of products, with particular reference to the design process and design for safety, for production, for cost, for assembly and to illustrate products with the appropriate technical terminology and by means of symbolic graphic representations according to regulations.

PREREQUISITES

It is advisable to pass the exam 94800 Fondamenti di Costruzione di Macchine before 84339 COSTRUZIONE E DISEGNO DI MACCHINE.

EXAM DESCRIPTION

The exam includes a written test and an oral test.

Students with SLD, with disabilities, or with other regularly certified special educational needs will agree with the teacher on the exam method and the compensatory instruments, by contacting the instructor at least 10 days before the exam. They will also be able to take advantage of the additional time required by law.

The written test consists of an exercise to be solved within 2 hours. During the test, only the use of the calculator is allowed. Smartphones have to be switched off.

Those who obtain a score of at least 18/30 for the written test can access the oral exam. Those who do not pass the written test have to repeat it in any official scheduled date.

The oral exam, which can be held within a calendar year after passing the written test, includes two questions: one on the topics of Machine Design and one for those of Machine Drafting. A failed oral exam does not invalidate the written test which can be reused in the future (within one year).

The final mark is given by the average of the marks of the oral and written tests: if it is a decimal, it is rounded to the upper unit.

ASSESSMENT METHODS

The written test assesses the student's ability to:

• schematize a device by converting its elements to types that can be solved with algorithms (beams, plates, etc.)
• apply the appropriate constraints between the various elements and between them and the frame
• schematize the loads acting on the structure
• draw the characteristics of stress in specific sections
• identify the most stressed areas
• dimension the critical areas by choosing the right material
• unambiguously present the product, according to the European projections method

The oral exam focuses on the topics faced during the lectures and aims to assess to which extent the student:

• has assimilated an adequate level of knowledge about the legislation
• has acquired the ability to logically face problems that will be posed during the test
• can illustrate theories and solve problems
• expresses his thinking clearly
• uses appropriate terminology
• uses a methodological approach oriented to manufacturing feasibility
• interprets and formulates principles related to the description of parts in a univocal, unambiguous and non-redundant manner
