Flapwise bending vibration analysis of double tapered rotating Euler-Bernoulli beam by using the differential transform method

In this study the out-of-plane free vibration analysis of a double tapered Euler-Bernoulli beam mounted on the periphery of a rotating rigid hub is performed. An efficient and easy mathematical technique called the Differential Transform Method (DTM) is used to solve the governing differential equation of motion. Parameters for the hub radius rotational speed and taper ratios are incorporated into the equation of motion in order to investigate their effects on the natural frequencies. Calculated results are tabulated in several tables and figures and are compared with the results of the studies in open literature where a very good agreement is observed.
