温度变化对固支FGM输流管道横向振动的影响
Effect of temperature variation on transverse vibration of the clamped pipe conveying fluid made of functionally graded materials
摘要
Abstract
Based on the Hamilton principle, dimensionless quantities are introduced into the effect of temperature variation on transverse vibration of the clamped pipe conveying fluid made of functionally graded materials (FGM).The differential equations to the motion of FGM conveying pipe affected by temperature changes are obtained.Then, the symplectic method is employed to solve the thermal transverse vibration problem of FGM pipe conveying fluid with both ends clamped.The numerical results show that the imaginary part of the complex frequency of the vibration of pipe conveying fluid decreases with the increase of the flow velocity and the dimensionless temperature axial force of the pipe.The deflection response amplitude and the response period increase with the increase of dimensionless temperature axial force.关键词
