Dynamic model for free vibration and response analysis of rotating beams

摘要: Abstract A new modeling method for the vibration analysis of a rotating cantilever beam is proposed and compared to other methods. Applying Hamilton principle, equations axial, chordwise flapwise motions are derived. During derivation these equations, nonlinear von Karman strain corresponding linear stress used consider stiffening effect due rotation. The derived motion obtained from analytically numerically previous Computations natural frequencies time responses show that described more reliable than
