5) attached mass 附加质量 1. A unified formula of the attached mass of dynamic water pressure on the lock walls and the gates of the head bay of the Three Gorges Ship Lift is derived. 导出三峡升船机上闸首闸墙、航槽和工作门上动水压力附加质量的统一算式 ,利用直接滤频法分别求解上闸首...
of wide-height and immersion ratios.The added mass coefficient of the cylinder is calculated by integrating the hydrodynamic pressure and simplified formulas are proposed for engineering applications.The calculation results show that the simplified formulas are in good agreement with the analytical ...
2.2.1 Added mass The added mass effect is maybe the most relevant effect of the fluid on the structural response. Added mass effect highly decreases the natural frequencies of the submerged structure with respect to vacuum, while the mode shapes remain nearby the same. View article Dynamic behav...

The aim of this study is to develop a simplified formula for added mass coefficients of a two-dimensional floating body moving vertically in a finite water depth. Floating bodies with various sectional areas may represent simplified structure sections transformed by Lewis form, and can be used for...
Vortex-induced vibrationadded massvariation effectmodal analysistime domainIn this paper, a higher-order nonlinear oscillator model has been proposed to predict the characteristics of the vortex-induced vibration (VIV) of a cylinder with two degrees of freedom. First, the vibration equations of the ...
Define key words such as matter, mass, volume, density, and buoyancy. Use the density formula to solve density example problems for density, volume, and mass. Related to this Question What volume of a 15.0 % by mass NaOH solution, which has ...
For a single-degree-of-freedom (SDOF) oscillating system composed of a spring–shaft shaker and a floating body (or model), if ω′a, ka and ma represent the “undamped” natural frequency, the effective spring constant and the effective mass of the oscillating system with the floating body...
