“…The dynamic response of an intact beam due to a moving system has received a good amount of attention in the literatures [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], whereas to the authors' best knowledge, dynamic analysis of the delaminated beam under the action of moving oscillator has been studied only in Ref. [29].…”

“…The shear deformation and rotary inertia has been considered in this paper. The nonlinear dynamics of longitudinal ground vehicle traction have been investigated in detail by Olson et al [19]. Kargarnovin and Younesian [20] studied the response of an isotropic Timoshenko beam with uniform cross-section and infinite length supported by a generalized Pasternak-type viscoelastic foundation subjected to an arbitrary-distributed harmonic moving load.…”

Abstract. This paper presents the dynamic response of a delaminated composite beam under the action of a moving oscillating mass. In this analysis the Poisson's effect is considered for the first time. Moreover, the effects of rotary inertia and shear deformation are incorporated. In our modeling linear springs are used between delaminated surfaces to simulate the dynamic interaction between sub-beams. To solve the governing differential equations of motion using modal expansion series, eigensolution technique is used to obtain the natural frequencies and their corresponding mode shapes necessary for forced vibration analysis. The obtained results for the free and forced vibrations of beams are verified against reported similar results in the literatures. Moreover, the maximum dynamic response of such beam is compared with an intact beam. The effects of different parameters such as the velocity of oscillating mass, different ply configuration and the delamination length, its depth and spanwise location on the dynamic response of the beam are studied. In addition, the effects of delamination parameters on the oscillator critical speed are investigated. Furthermore, different conditions under which the detachment of moving oscillator from the beam will initiate are investigated.

“…A free-rolling wheel is defined to have a slipvalue of 0, while a locked wheel has a slip-value of 1 [1]. It is known that a hysteresis loop exists when a brake torque is applied [3]. This means that the brake torque where lockup occurs and where control is regained could be very different.…”

Summary. Nonlinear analysis techniques, especially methods from bifurcation theory, have emerged as valuable tools over the last 20 years, particularly due to the advent of the modern computer. Originally developed as part of dynamical systems and chaos theory, they gradually are finding their way into applications areas from all walks of life. As far as the aerospace industry is concerned, methods from nonlinear dynamics were used initially for the prediction of aircraft flight dynamics at high angle of attack flight regimes, where traditional methods have failed. They are now being used within Airbus to analyse aspects of the dynamics of aircraft on the ground. Specific aerospace applications, where nonlinear dynamics techniques are expected to make an impact, include the design of flexible structures and mechanisms, and the dynamics of a braking wheel. Challenges related to the industrialisation of such methods are also discussed.

“…Experimentally it was observed that the rolling friction coefficient depends nonmonotonously on the velocity [3]: For small velocities the rolling friction force increases with increasing velocity, while for fast motion it decays as the velocity grows. Furthermore, the cylinder is subjected to the drag force of the surrounding medium, e.g.…”

“…The rolling friction originates due to the dissipative and inertial resistance of the springs, which are compressed and subsequently decompressed when the cylinder rolls on the surface. As an important property this simple model leads to a nonmonotonous rolling friction as a function of the velocity [7] as observed in experiments [3]. Let us briefly sketch the main results of the model which will be used below.…”

We investigate the motion of a hard cylinder rolling down a soft inclined plane. The cylinder is subjected to a viscous drag force and stochastic fluctuations due to the surrounding medium. In a wide range of parameters we observe bistability of the rolling velocity. In dependence on the parameters, increasing noise level may lead to increasing or decreasing average velocity of the cylinder. The approximative analytical theory agrees with numerical results.
