|Title:||A rigid multibody method for free vibration analysis of beams with variable axial parameters|
|Abstract:||© SAGE Publications. This paper presents a new approach to the problem of determining the frequencies and mode shapes of Euler-Bernoulli tapered cantilever beams with a tip mass and a spring at the free end. The approach is based on the replacement of the flexible beam by a rigid multibody system. Beams with constant thickness and exponentially and linearly tapered width, as well as double-tapered cantilever beams are considered. The influence of the tip mass, stiffness of the spring, and taper on the frequencies of the free transverse vibrations of tapered cantilever beams are examined. Numerical examples with results confirming the convergence and accuracy of the approach are given.|
