Syllabus of lectures:

Outline:

1.Computational models of mechanisms - system of discrete elements (mass, spring, shock absorber).

2.Determination of kinetic motion equations from equilibrium conditions or by means of Lagrange's equations.

3.Free and forced vibration of mechanical systems with one or two degrees of freedom (solution of kinetic equations with zero or periodical right side) - amplitude and frequency characteristics, resonance, antiresonance, influence of vibration damping etc.

4.Vibration excited by centrifugal forces, by the road surface bumpiness, etc.

5.Tuned damper of the longitudinal or torsion vibrations.

6.General periodical excited forces and motions - application of Fourier's analysis.

7.Fundamentals of the theory of motion stability - definitions, method of characteristic exponents etc.

Keywords:

vibration of linear mechanical systems, computational model, discrete elements - mass, spring, viscous damper, kinetic equations of motion, free and forced vibration, degrees of freedom, resonance and antiresonance, Fourier transform, stability of motion, method of characteristic exponents
