Detailed description of topics:

The course is designed to give a overview of essential mechanical topics relevant for production techniques, mechatronics and system designers. The main topics that will be handled are:

- Vibration analysis of structures (modal analysis, theory/experimental, damping, non-linearities)

- basics of rotor dynamics

- Multi-physical aspects of models (electrostatic coupling of microstructures, thermo-mechanical coupling, vibro-acoustics)

- Static stability of structures (buckling), non-linearities (geometrical/material), visco-elasticity of materials and fracture

The course is intended to give an overview of the important phenomena and to give guidelines for further modeling and solving of structural analysis problems.

Remarks assessment, entry requirements, etc.:

The course will be assesed by an exam and a project exercise

Learning goals:

The student must be able to:

  1. recognize and analyse the effects of the coupling of structural parts with  electrostatic forces, acoustic pressure and piezo-electric mechanics. In particular is able to analyze how those effects are utilized in mechatronical designs

  2. evaluate the effect of gyroscopic forces on the dynamics of rotors

  3. compute the linear dynamic response of mechanical systems excited by random forces

  4. analyze the stiffness and strength of simple composite materials

  5. evaluate the visco-elastic properties of materials and use their constitutive description in numerical modelling

  6. evaluate the sensitivity of designs with respect to general design parameters (geometry and material parameters) and apply optimization procedures to improve basic designs

Computer use:

Computer tools will be used (Matlab and/or Ansys) for the project exercise

Laboratory project(s):

None
