文摘
- •
Frequency response of axially loaded beams with viscoelastic dampers is studied.
- •
Translational and rotational Kelvin–Voigt viscoelastic dampers are considered.
- •
Theory of generalized functions is used in conjunction with Euler–Bernoulli beam theory.
- •
Exact closed-form frequency response is built for any number of dampers and point/polynomial loads.
- •
Characteristic equation is built as determinant of a 4×4 matrix for any number of dampers.
