Objectives of the course
The module is intended to help the student acquire the basic methods for outlining the analysis of the mechanical systems from the
kinematic, static and dynamic points of view. The course intends to achieve the described objectives adopting a reduction in
engineering, therefore the treatment of the kinematic, static and dynamic count as applicative examples executed considering the typical
mechanical systems, normally dealt with in the motor vehicle sector.
Expected skills
The student must acquire the instrumental methodology in order to plan the study of kinematcs, statics and dynamics of a mechanical
system.
Prerequisites
It is considered necessary a fundamental knowledge of the integral and differential calculus, the fundamentals of the vector calculus and
a preliminary knowledge of kinematics and dynamics.
Syllabus
Introduction to the costitutive parts of the engine. Examples of mechanical systems with rigid and flexible transmission.

Kinematics of the rigid body. Coupling betwen rigid bodies: bearings, sockets, cams, screws-lead screws, linear guides.
The use of
typical systems in the motor vehicle sector.

Kinematics of relative movements. Articulated mechanisms.
Examples aimed at the study of the throttle
Dynamics of the mechanical systems on the flat and in space, strength and momentum, cardinal equations, diagram of the free body.

Examples used for the study of typical mechanical systems. Articulated mechanisms.

Fundamental laws on friction: sliding and rolling friction, stalling, roller guides. Examples of wheels and vehicle motion.

Tappet and cam systems.

Use of the energy equation and of the theorems of quantity of and the momentum of the quantity of motion. Study of the impact.

Reduction of the inertia strength. Dynamic actions on rating parts. Dimensioning of fly wheels and balance of the rotors.

Mechanical vibrations. Free and strengthened linear vibrations of systems at a lower degree. Approach to the study of vibration of
sytems at a higher degree. Examples connected to automobile suspension.
Laboratories and/or exercises
There will be classroom training aimed at the solution of problems inherent to the topics covered in the lessons.


Bench tests dedicated to the experimental study of vibrations, will be carried out. There is also programmed an activity for the modelling
and simulations of mechanical systems.
