Dynamical 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 کاملOn stability of a clamped-pinned pipe conveying fluid
In the past, stability of an undamped clamped-pinned pipe conveying fluid has been always considered numerically leading to controversial results. Païdoussis (2004) has shown that a numerical stability analysis of a clamped-pinned pipe requires exceptionally large number of vibration modes to obtain the correct dynamical behaviour. In this paper, analytical proof of stability of a clamped-pinne...
متن کاملGradient-Based Optimization of Flexible Multibody Systems Using the Absolute Nodal Coordinate Formulation
Lightweight techniques are applied increaslingly often for modern machine designs, such as industrial robots or machine tools, to reduce the moving masses and therewith the energy consumption. However, as a result the stiffness decreases and considerable deformations arise. Thus, for a proper system analysis the method of flexible multibody systems has to be employed. For the optimization of su...
متن کاملIntegration of the Equations of Motion of Multibody Systems Using Absolute Nodal Coordinate Formulation
Recently, a finite element formulation, called the absolute nodal coordinate formulation (ANCF), was proposed for the large rotation and deformation analysis of flexible bodies. In this formulation, absolute position and slope coordinates are used to define the finite element configuration. Infinitesimal or finite rotations are not used as nodal coordinates. The ANCF finite elements have many u...
متن کاملDynamic Contact between a Wire Rope and a Pulley Using Absolute Nodal Coordinate Formulation
Wire rope and pulley devices are used in various machines. To use these machines more safely, it is necessary to analyze the behavior of the contact between them. In this study, we represent a wire rope by a numerical model of a flexible body. This flexible body is expressed in the absolute nodal coordinate formulation (ANCF), and the model includes the normal contact force and the frictional f...
