This paper deals with the static large deflpetion and the large amplitude free flexural ibration of a symmetrically laminated orthotropic eliiptical plted with a simply equations of the plated in terms of the deflection and two inplane displacemets is presented by use of a modified Galerkin procedure. Two inplance equations of equilibrium and the associted inplance bonndary eonditions are satified axaotly. Numerical Comatations are performed for stsatic and dynamic responses of homogenceous and symmetric cross-plyelliptical plates with different axes rations, numbers of layers and high-modulus material properties. In the static and dynamic linear caasea, preent reaults are compared with avaliable data.

The prolem of bearm-plates with as delamiation located at an arbitrary site undergjoing nonlinear free vibration without damp is investigated, For this problem. Noalinear govning equations a well as the contiunity. Equilibrium and compaibility conditions are esablished. The Galerkin method and harmorie balance method are employed to find solutions. Filnslly, in some examples. amplitude-frequeney curves of the deiaminated structure are presented in order to reveal some special dynamic features.

【期刊论文】ANALYSIS OF THE CHAOTIC MOTION FOR A ROTOR SYSTEM WITH A TRANSVERSE CRACK

The chaotic motion of an elastic shaft-disk rotor system including the geometric nonlinearity of the shaft with a transverser crack is investigated. The critical condition for the system to enter chaotic state is given by the Melnikov method. Meanwhile, whether the chaos occurs is determined by the Poiacare map, phase portrait and time-displacement history diagram.

Based on Hamilton's principle and the Timoshenko-Mindlin hypotheses on moderately thiek plates, a set of non-linear governing equations of motion for truncated conical moderately thick shells is sen up in large overall motion. By using the Galerkin method and the harmonic balance method, the problem of non-linear vibration of the truncated conical moderately thick shelts is analzed. The present results are compared with the available data for speciat cases.

【期刊论文】ANALYSIS OF NON-LINEAR DYNAMIC STABILITY FOR A ROTATING SHAFT-DISK WITH A TRANSVERSE CRACK

In this paper, the nonlinear dynamic stability of a rotating shaft-disk with a transverse crack is studied, The crack and the disk are located in arbitrary positions of the shaft respectively. Using the equivalent line-spring model, the deflections of the system with a crack are constructed by adding a deflection to the deflections of the uncracked system. The unstable regions are confirmed by Runge Kutta method and the Floquet theory. The effects of crack depth, crack position, disk position, disk thickness and rotating speed on the principal unstable regions are discussed. The numerical results are compared with available data.
