Modeling of Flexural Beams Subjected to Arbitrary End Loads
(The American Society of Mechanical Engineers (ASME), 2002)The analysis of compliant mechanisms is often complicated due to the geometric nonlinearities which become significant with large elastic deflections. Pseudo rigid body models (PRBM) may be used ... -
Optimum Stiffener Layout for the Reduction of Vibration and Noise of Gearbox Housing
(The American Society of Mechanical Engineers (ASME), 2002)Dynamic excitation from the gears generates vibration modes in the gearbox which causes radiation of unwanted structure-borne noise. To reduce the noise as well as the vibration, the stiffened ... -
