Stability Optimization of Functionally Graded Pipes Conveying Fluid
This paper presents an exact analytical model for optimizing stability of thin-walled, composite, functionally graded pipes conveying fluid. The critical flow velocity at which divergence occurs is maximized for a specified total structural mass in order to ensure the economic feasibility of the attained optimum designs. The composition of the material of construction is optimized by defining t...
متن کاملStabilization of Electrostatically Actuated Micro-pipe Conveying Fluid Using Parametric Excitation
This paper investigates the parametric excitation of a micro-pipe conveying fluid suspended between two symmetric electrodes. Electrostatically actuated micro-pipes may become unstable when the exciting voltage is greater than the pull-in value. It is demonstrated that the parametric excitation of a micro-pipe by periodic (ac) voltages may have a stabilizing effect and permit an increase of the...
متن کاملDynamical stability of cantilevered pipe conveying fluid in the presence of linear dynamic vibration absorber
When the velocity of fluid flow in a cantilevered pipe is successively increased, the system may become unstable and flutter instability would occur at a critical flow velocity. This paper is concerned with exploring the dynamical stability of a cantilevered fluid-conveying pipe with an additional linear dynamic vibration absorber (DVA) attachment. It is endeavoured to show that the stability o...
متن کاملFlow-Induced Vibration Analysis of Supported Pipes Conveying Pulsating Fluid Using Precise Integration Method
Dynamic analysis of supported pipes conveying pulsating fluid is investigated in Hamiltonian system using precise integration method PIM . First, symplectic canonical equations of supported pipes are deduced with state variable vectors composed of displacement and momentum. Then, PIM with linear interpolation formula is proposed to solve these equations. Finally, this approach’s precision is te...
متن کاملAnalysis of the Effect of Fluid Velocity on the Instability of Concrete Pipes Reinforced with Nanoparticles Conveying the Fluid Flow
With respect to the great application of pipes conveying fluid in civil engineering, presenting a mathematical model for their stability analysis is essential. For this purpose, a concrete pipe, reinforced by iron oxide (Fe2O3) nanoparticles, conveying fluid is considered. The goal of this study is to investigate the structural stability to show the effects of the inside fluid and the nanopart...
