In this study the characteristics of a mobile crane are obtained by using a flexible multibody dynamics approach, for the determination of safe loads to prevent tipping of a mobile crane. Only the boom of the crane is assumed to be flexible since it is the only element that has considerable deflections in applications. The coupled rigid and elastic motions of the crane are formulated and software is developed in order to carry out the dynamic analysis. The variation of piston force with respect to boom angular position for different boom motion times are simulated, load curves are generated and the results are compared with the experimental results obtained from a 10 t mobile crane.

Fluid-structure interactions with both structural and fluid nonlinearities Bendiksen, O. O.; Seber, G. (Elsevier BV, 2008-08-19) In this study, we consider a class of nonlinear aeroelastic stability problems, where geometric nonlinearities arising from large deflections and rotations in the structure interact with aerodynamic nonlinearities caused by moving shocks. Examples include transonic panel flutter and flutter of transonic wings of high aspect ratio, where the presence of both structural and aerodynamic nonlinearities can have a dramatic qualitative as well as quantitative effect on the flutter behavior. Both cases represent i...
NONLINEAR DYNAMIC-MODEL AND ITS SOLUTION FOR A HIGH-SPEED CAM MECHANISM WITH COULOMB-FRICTION Ünlüsoy, Yavuz Samim; Tümer, Sami Turgut (Elsevier BV, 1994-01-20) The dynamic behavior of overhead cam mechanisms, commonly used in automotive applications, is strongly influenced by the Coulomb friction at the rocker arm pivot. In this study, a non-linear one-degree-of-freedom model of such a mechanism including Coulomb friction has been developed. An exact quasi-linear solution to the equations representing the non-linear behavior has been obtained. The effects of Coulomb friction at different cam speeds are investigated using typical parameter values. A critical examin...
TORSIONAL VIBRATIONS OF LAYERED COMPOSITE PARABOLOIDAL SHELLS Kayran, Altan (Elsevier BV, 1990-09-08) An analysis is presented for the torsional vibration characteristics of layered composite paraboloidal shells. The conditions for the uncoupling of the torsional modes from the bending and extensional modes are first determined for a layered shell of revolution. A finite difference scheme is developed for the solution of the resulting governing equation for the uncoupled torsional frequencies. The results of the finite difference solution for the paraboloids are compared with the analytical solution of unco...
One-dimensional dynamic microslip friction model Ciğeroğlu, Ender; Menq, Ch (Elsevier BV, 2006-05-09) A one-dimensional dynamic microslip friction model, including the damper inertia, is presented in this paper. An analytical approach is developed to obtain the steady-state solution of the resulting nonlinear partial differential equations when subjected to harmonic excitation. In the proposed approach, according to the excitation frequency, a single mode of the system is considered in the steady-state solution for simplicity; consequently, phase difference among spatially distributed points is neglected. T...
DYNAMIC ANALYSIS OF GEARED SHAFT SYSTEMS BY USING A CONTINUOUS SYSTEM MODEL Şener, Ö Sedat; Özgüven, Hasan Nevzat (Elsevier BV, 1993-09-22) In this study dynamic mesh forces and dynamic factors in a geared shaft system are studied by using a continuous system model. The system consists of a gear pair, two shafts carrying gears, and two inertias representing drive and load in the system. A continuous system model is used to include the shaft inertias, which are usually disregarded even in most of the sophisticated models. The primary aim of this work is to provide a tool for studying the effect of shaft inertia in gear dynamics, and to present s...
