FREE VIBRATION OF A SIMPLY SUPPORTED BEAM CARRYING A RIGID MASS AT THE MIDDLE A comprehensive study on the lateral vibration of a simply supported beam carrying a concentrated mass at the center of beam is made. It has been found tha... CH Chang - 《Journal of Sound & Vibration》 被引量...
Equations of motion are derived from Hamilton`s principle. Analytical solutions for the bending and free vibration analysis are obtained for simply supported plates. The accuracy of the present solutions is verified by comparing the obtained results with those predicted by classical theory, first-order...
Dynamic analysis of an inclined Timoshenko beam traveled by successive moving masses/forces with inclusion of geometric nonlinearities In the first part of this paper, the nonlinear coupled governing partial differential equations of vibrations by including the bending rotation of cross se...

Under the assumption of steady-state fasting conditions, the equations describing the behaviour of the feedback loop can be solved for constant structure parameters. Here, we were interested in the gains of beta cells (Gβ) and insulin sensitivity (GR). From the model equations Gβ can be es...
