Content, progress and pedagogy of the
module
Purpose
- to contribute to students’ attainment of knowledge and
comprehension of systematic methods for modelling complex
mechanical structures and non-rigid (flexible) mechanical
structures, and further to achieve knowledge and comprehension
about advanced dynamics equations and solutions for motion of
systems with rigid or non-rigid bodies.
- to contribute to students’ attainment of knowledge and
comprehension of fluid power systems and components and enable them
to analyze and model such systems.
