Preliminary identification of damping properties of tonewood
Original language description
Besides elasticity parameters, damping of the material is the crucial parameter of the function of a violin and also of other stringed instruments with a wooden soundboard. Assuming tonewood as an orthotropic linear elastic continuum, our aim is to contribute to hypothesis, that each orthotropic elastic constant has its appropriate loss factor - partial dampings. Dynamic experiments are based on the impulse excitation and the steady state harmonic response is calculated by Fourier transform of time-sampled measured signals (excitation and response). Frequency transfer function fitting identification method can determine complex modal and spectral eigen-parameters, mainly eigenfrequencies and eigendampings.
