Objectives of the course
The module intends to instruct the students on the fundamental laws which regulate the functioning of mechanical devices and proposes
to provide the necessary knowledge for functional analysis of mechanical components and the dynamic analysis of the mechanical
systems. The fundamental concepts of tribology will be presented, description of the main mechanical friction components, the most
common transmission components, gears with straight and helical teeth, bevel gears, the gear trains, the differential gears, the speed
gears. Finally, there will be an approach to the useful methodology for the study of the transients and vibrations of mechanical systems.
For the treatment of each subject there will be provided an example in the field of motor vehicles.
Expected skills
The student must acquire the methodology useful for applying the study of the dynamics of a mechanical system and the knowledge
necessary for carrying out functional dimensioning of the principal mechanical components.
It is considered necessary the knowledge of the methodology and contents provided by the Basic Mechanics course.
The principles of trbology, Wear and Tear mechanisms. Types of friction. Outlines on the transmission of force on the wheel on-road
surface contact.

Mechanical friction components: Brakes and friction clutches. Outline of brakes and car clutches. Outline of synchronizers.

Power transmission components with flexible parts: toothed and V-belts, chains and cables. Examples of gear changes and car
transmission technology. Screw-lead screw transmission.

Connections with transmission coupling. Cardan joints. Constant velocity joints.

Sliding, rolling and lubricated supports. Outlines of the variations of the characteristics of the supports with use.
Gearing transmissions. Spur gears, helical gears, bevel gears. Crossed helical. Worm- worm gear. Outlines of other types of gears

Ordinary and epicycle gears. Differentials. Speed gears. Examples of car gears.

Fluid transmission elements. Examples of braking systems.
The study of transient in mechanical systems.
Motor-reducer-user. Mechanical characteristics of motors and users.

Mechanical Vibrations. Basic formulation of the calculations of the critical speeds. Examples of suspension systems and transmission
Laboratories and/or exercises
Classroom training aimed at the solving of problems inherent to the subjects treated in the lessons. An activity for the development of
mechanical system projects regarding typical use for cars.

Training at the benches is programmed dedicated to the experimental characterizations of engines, gear speed reducers and belt drive
systems. There is also programmed a computer activity of modelling and simulazione of mechanical systems.
