| Aim: To make the student able to apply Mechanical Physics and equivalent electric circuit models for vibrating systems in order to analyse the dynamic mechanical behavior of electronic equipment and to assess the strength characteristics of selected construction materials. |
Contents: Analogies between mechanical, acoustic and electric systems.
Mechanical, acoustic and electric circuit elements.
Admittance and impedance networks for mechanical and acoustic systems.
Equivalent electric network models for mixed mechanical, acoustic and electric systems.
Coupling of admittance and impedance networks.
Transformation of a coupled network to the mechanical, acoustic or electric side. Inversion of networks.
Analysis and design of practical, mixed mechanical, acoustic and electric systems based on equivalent electric network models.
Calculation of acceleration, speed, amplitude, forces and sound pressure of vibrating systems.
Mechanical characteristics of materials. Hooke's law.
Design for strength and stiffness of mechanical construction elements for electronic equipment. |
