摘要
An exact solution of the title problem is presented. The overall situation is of great interest in many engineering applications. Three combinations of boundary conditions for the structural element are considered: simply supported, simply supported - clamped and clamped at both ends. An analysis of the situation where the spring-mass system acts as a dynamic absorber cancelling out the motion at the point of attachment for certain modes of vibration is presented. An independent solution has also been obtained by means of a finite element code in order to ascertain the validity and accuracy of the results predicted by the exact solution of Timoshenko’s dynamic differential system. © 1993 Academic Press Limited.
