Dynamic Analysis of Rotating Composite Beam and Their Numerical Analysis Using COMSOL

Rotary beams play a significant role in engineering structures such as turbine blades, aircraft propellers and robotic manipulators. In this paper we have studied the analytical and numerical analysis of composite beam in dynamic condition. Centrifugal Force acts on the beam while rotating it at different RPM. By using this concept the analytical study is carried out for this rotating beam in which centrifugal forces are calculated for different RPM. Due to this force stress is induced in the beam at different locations. Also the elongation of the beam will take place in rotating condition. The analytical study has been carried out for measurement of stresses and elongation of beam. For the measurement of elongation of beam we have used the Finite Element Method (FEM). The analysis of beam is also carried out using COMSOL. In this software, the test specimens were modeled in accordance to analytical specimens. The numerical study is concerned with stresses induced and elongation of rotating composite beams for different rpm. This study is important to understand the effect of RPM on Stress, Elongation. After this study we have observed that there is no much difference between in the both analysis. The study of beam has been carried out at various end conditions of the beam.
