Dynamic Characterastics of Beam Structures with Attachments

Abstract:

Beam structures are commonly found in the fields of engineering. Since in practical cases the subsystems are attached with respect to beams due to the need of the engineering, and the concentrated masses are only an approximation to the reality. This paper considers the dynamic characterastics of the Euler-Bernoulli beam with Attachments. The beam is supported elastically by transverse and torsional springs. The present study is concerned with the dynamic characterastics of the beam structures with arbitrary number of the elastically mounted masses at arbitrary positions by utilizing the method basing on the theory of integral equation and the theory of generalized function. The results are presented for the natural frequencies of the beam structures with the concentrated mass and oscillators. To verify the validity and accuracy of the present method, the experimental results are obtained utilizing the method of spectral analysis. These results provide a better understanding of the problem described and may be of interest to experimentalists and design engineers
