AIMS AND CONTENT

LEARNING OUTCOMES

The student will learn the most relevant phenomenological aspects of machine mechanics, as well as the foundations of kinematics, static and applied dynamics. He will also be able to discuss and analyze the morphological and functional characteristics of the main components of drives and mechanical transmissions.

Teaching methods

Theoretical lessons integrated with examples and exercises.

SYLLABUS/CONTENT

Introduction to the Mechanics of Machines.
Constraints, kinematic pairs, topology, characteristics and mobility of the kinematic chains.
Contact forces and friction between solids. Forces between solids and fluids. Embodiment of kinematics pairs.
Kinematics of planar mechanisms: position and velocity models with analytical and geometric approaches.
Statics of planar mechanisms: constraints and reactive forces; determination (with analytical and geometric approaches) of reactive and motor forces/torques acting on a mechanism. Principle of virtual works. Transmission of forces.
Dynamics of mechanical systems with constant transmission ratio, with one degree of freedom: balance of mechanical power; efficiency and power flows; static characteristics of motors and loads; motor-load coupling; use of mechanical transmissions; steady state operating conditions; reduction to a free coordinate of forces, torques and inertias.
Free and forced vibrations of mechanical systems with one degree of freedom.
Mechanical transmissions: gears; ordinary and planetary gearings. Mechanical transmissions with deformable members: belts and chains.  Systems with ropes (hoists)
