TL;DR: In this article, a comprehensive study on the influence of rotatory inertia, shear deformation and tip load on the vibration behavior of one-link flexible manipulators is presented, and explicit solutions of the asymptotic behavior of high order modal frequencies and vibration modes are given and verified with the numerical results.

TL;DR: In this paper, both finite element and boundary element approaches for calculating fully-coupled added mass matrices are presented and illustrated, and the boundary element approach uses the NASHUA structural acoustics program in combination with NASTRAN to compute the added mass matrix.
Abstract: Both finite element and boundary element approaches for calculating fully-coupled added mass matrices are presented and illustrated. The finite element approach is implemented using existing structural analysis capability in NASTRAN. The boundary element approach uses the NASHUA structural acoustics program in combination with NASTRAN to compute the added mass matrix

TL;DR: In this paper, an exact analytical method is developed for the problem of wave radiation by a uniform cylinder in front of a vertical wall, and numerical analysis has been carried out in detail in order to discuss the influences of the distance between the cylinder and the vertical wall and water depth on the added mass and radiation damping ofthe cylinder.
Abstract: In this paper, an exact analytical method is developed for the problem of wave radiation by a uniform cylinder in front of a vertical wall. Based on the image principle, the hydrodynamic problem ofa cylinder in f ofa vertical wall is transf ormed into the equivalent problem ofdouble cylinders in unbounded fluid domain. Consequently, an analytical method ofeigenf unction expansion is adopted to calculate the radiation ofthe cylinder due to the motion in surge, sway, roll and pitch, respectively. Moreover, numerical analysis has been carried out in detail in order to discuss the influences ofthe distance between the cylinder and the vertical wall and water depth on the added mass and radiation damping ofthe cylinder. It is shown that added mass and damping ofthe cylinder in f ofa vertical wall are evidently different from those in case of the cylinder in unbounded fluid domain from the numerical results. It is also found that the added mass and radiation damping oscillate with wave number, and the oscillating frequency increases with the increasing of the distance between the cylinder and the wall. # 2003 Elsevier Ltd.

TL;DR: Numerical modeling and testing of a complex-shaped remotely-operated vehicle (ROV) are shown and the proposed method is able to determine most of the hydrodynamic added mass coefficients of the open frame ROV.
Abstract: In this paper, numerical modeling and testing of a complex-shaped remotely-operated vehicle (ROV) are shown. The paper emphasizes on systematic modeling of hydrodynamic added mass using computational fluid dynamic software WAMIT^(TM) on the open frame ROV that is not commonly applied in practice. From initial design and prototype testing, a small-scale test using a free-decaying experiment is used to verify the theoretical models obtained from WAMIT^(TM). Simulation results have shown to coincide with the some of the experimental tests. The proposed method is therefore able to determine most of the hydrodynamic added mass coefficients of the open frame ROV.
