摘要

Experimental investigations of the dynamic behaviour of tapered rods of power-law profile covered by narrow strips of absorbing materials show a trend towards efficient damping of flexural vibrations in such structures. The advantage of applications of this unique damping technique is especially noticeable in the medium and higher frequency range. Experiments carried out for free rods of quadratic profile and for the same rods covered by adhesive strips of absorbing layers demonstrated noticeable suppression of resonant vibrations. This can be attributed to a significant reduction of the reflection coefficients of flexural waves from the sharp tips of the rods. The results of these measurements also showed more significant damping obtained in the rod with the lower value of quadratic parameter. Damping systems containing rods of power-law profile offer a variety of application possibilities. In particular, they can be applied for damping flexural vibrations in aerospace and civil engineering structures as well as in tennis racquets and golf clubs.
