Some dis-assembling/assembling activities are proposed in order to analyse the architecture and the principle of industrial systems which are based on motion transformation or power transmission system: cams (fishing reel, floor spring), pumps and hydraulic motors, automatic and manual gear boxes, braking systems (from bikes to tanks!) etc... The comparative study of technical solutions uses models and associated design rules that presented in class.

Some testing devices allow the identification of parameters for locals models (contact, friction, wear, ...) or global models of systems (hydrodynamic coupling). The experiments will feed the models to make them usables during design sessions.
