TL;DR: In this paper, the dynamic interaction between the balancing ball and the rotor was investigated using an undamped three-degrees-of-freedom system model in a rotating reference frame, and the results showed that the automatic balancer can neutralize the unbalance whirling motion of the rotor, when operated at speeds higher than its critical speed.

TL;DR: In this article, the natural vibration of a circular membrane backed by a cylindrical air cavity is investigated using the multimodal approach, where the cavity-backed membrane is modeled as a dynamical system composed of two subsystems, and their modal receptance or inverse receptance characteristics are used to study the system vibration.

TL;DR: In this article, the dependence of the steady deflection and the natural vibration of the plate on the strength of the electric field was investigated, and it was shown that as the field strength increases, the constant bias voltage between the diaphragm and the base plate of a condenser microphone introduces a deflection load intensity on the microphone, and since this load intensity increases with deflection, the voltage has a destabilizing influence on the plate vibration.

TL;DR: The recurrence scheme presented in this article is quite convenient for computer implementation and two dimensional boundary characteristic orthogonal polynomials have been generated using the present scheme for a variety of geometries.

TL;DR: In this article, the boundary condition of a structure is considered and the resulting sound radiation due to excitations applied at any point on the structure depend very strongly on the boundary conditions.
Abstract: Structural response and the resulting sound radiation due to excitations applied at any point on the structure depend very strongly on the boundary condition. Constraining structural vibration to t...
