Description: An increasing demand for designing reliable and high-performance mechanical systems such as hydraulic cranes, wind turbines or robotic systems requires in-depth understanding of dynamic behavior of the systems, which can be achieved by modeling and simulation at the system level.
The course is aimed to provide basic concepts of mechanics of multibody mechanical systems for the purpose of modeling and simulation. The course deals with the formulation and solutions of dynamic equations of multibody systems. Both rigid and flexible systems in planar and spatial movements will be considered.
The topics will include kinematic analysis with constraints, analytical dynamics, and numerical integration of the equation of motion. The dynamic modeling of flexible multibody systems will be introduced. Dynamic modeling with MSC Adams is demonstrated with their applications in industry in the workshop.
Prerequisites:
Knowledge of linear algebra, rigid body kinematic and dynamics, ordinary differential equations
