Mechanical Design


The design of mechatronic machines and systems can currently be performed by many sophisticated technologies based on the appropriate use of computer aided tools. Therefore, transversal skills are needed, ranging from CAE tools to design of experiments, which allow a quick comparison of the effectiveness of the various alternative design solutions.

The study of vibrations represents a topics of great importance for machine mechanics. Vibration problems occur in general in mechanical systems subject to high dynamics motions or loads, such as unbalanced rotors and reciprocating mechanisms.

Multibody systems are mechanical systems consisting of several links, stiff or compliant, subject to relative movements due to the deformability of the bodies or the presence of various types of kinematic pairs and constraints. Present simulation tools allow to evaluate the interaction forces and the kinematic and dynamic performances of these machines even when subject to high accelerations and deflection of the links. Robots and machine tools, automatic machines, vehicles and many other mechanical systems are typically designed with these tools.

When the bodies or even mechanical systems are characterised by significant deformations during the operation, the study becomes more complicated, compared to the case of rigid body models. The Machine Mechanics team deals with this type of problems through the development of numerical models based on the use of commercial software tools or with the development of specific analytical models solved numerically.
