Six-degree-of-freedom Sensor Fish design - Governing equations and motion modeling
TL;DR: In this paper, the authors describe a general formulation for the coordinate systems, equations of motion, force and moment relationships necessary to simulate the 6DOF movement of an underwater body, by considering the Sensor Fish device to be a rigid, axisymmetric body.
Journal ArticleDOI
Frequency characteristics of photoacoustic signals generated in liquids
TL;DR: In this article, photo-acoustic signals generated in liquids are analyzed as a function of light modulation frequency using the assumption that the thermal diffusion length is negligibly smaller than the radius of the incident laser beam which has a Gaussian distribution.
Automated Response DOF Selection for Mapping of Experimental Normal Modes
TL;DR: In this paper, a direct method for response measurement degree-of-freedom (dof) selection to map experimental normal modes is described and demonstrated, which utilizes a detailed pre-test finite element model of the subject structure.
Journal ArticleDOI
Vibrations of double-span uniform beams subject to an axial force
TL;DR: In this article, the determination of natural frequencies of transverse vibrations of simply supported, clamped, and clamped-simply supported beams with an intermediate support subject to an axial force was dealt with.
A modeling approach to hybrid isolation of structure-borne sound
TL;DR: In this paper, a combination of passive and active isolation is used to reduce interior noise levels of a vehicle and obtain a better isolation performance, and different actuator configurations and sensor strategies of the active isolation part are investigated.
