The solution of the problem exhibits a weak interior layer and a strong boundary layer. In these layers, the physical variable changes rapidly over small domains in space and in a short time interval. The solution reveals a multiscale character, which adds stiffness to the problem. We present a second-order accurate difference approximation based on the defect correction method to capture this multiscale phenomenon. The problem is discretized by an implicit Euler scheme in time variable on a uniform mesh and a defect correction method consisting of the upwind scheme and the central difference scheme in space variable on a layer-adapted mesh in such a way that it captures the interior as well as the boundary layers. The proposed method is not only free from directional bias but unconditionally stable and converges uniformly.

The upper state can be rendered asymptotically stable, yet it does not cost any constant dissipation of energy, and only a transient energy dissipation is needed. Asymptotic stability under a single perturbation does not imply stability with respect to multiple perturbations. For a range of pendulum–controller interactions, there is also a regime where constant energy dissipation is needed for stabilization.

Owing to the improved passivity, the proposed controller ensures the effective suppression of payload oscillations and robustness. Moreover, the control design is extended with the hyperbolic tangent function to prevent overdriving the trolley. The asymptotic stability is guaranteed by LaSalle's invariance principle.

response of cargo like pendulum vibration under three dimension vehicle hull motions. A nonlinear two degree-of-freedom model of the cargo inside vehicle hull is developed and analyzed. Equations of pendulum motion are obtained by first order Lagrange equations using Lagrange multiplier for constrained system with one constraint equation. One or two independent bumpers of the securing cargo are considered in the model. In model of two bumpers between them is right angle. Bumpers forces are represented by a special stiffness and damping as a function of the displacement and motion velocity. Investigation was made for three kinds of pendulum motion: transient motion from free initial conditions without hull vibrations; stationary motion exciting from constrained string or hull bumpers vibrations; jointly transient and exciting motion. The investigation was made for one, two and tree component harmonica motion of hull. Additional investigation of motion with random excitation was observed. From mathematical modeling the optimization of geometric parameters like length of string and gap between bumpers and pendulum was made. It is found out that processes of transient motion are very short when gap is "negative". In additional is found out that by special harmonica frequency start vibro shock motion with large amplitude. Recommendation of investigation may be used for cargo fasten inside trailer, ship or airplane.}, keywords = {Nonlinear vibrations; cranes; cargo pendulum motion; vehicle hull vibrations; vibroshock motion}, year = {2008}, pages = {169-172} } @inproceedings{MTMT:2836256, title = {The high dimensional harmonic balance analysis for second-order delay-differential equations}, url = {https://m2.mtmt.hu/api/publication/2836256}, author = {Liu, L and Kalmár-Nagy, Tamás and Dowell, E H}, booktitle = {ASME 2007 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference}, doi = {10.1115/DETC2007-34396}, unique-id = {2836256}, abstract = {In this paper we demonstrate the utility of the High Dimensional Harmonic Balance (HDHB) method to compute periodic orbits of second-order delay-differential equations. In particular, the method has been successfully applied to capture the unstable limit cycles of a model of regenerative machine tool vibrations. Both the conventional harmonic balance and the HDHB methods are employed to investigate the dynamic behavior of the nonlinear delay equation. The results show an excellent agreement with those from time domain solutions. The advantages of HDHB over the classical Harmonic Balance method are highlighted and discussed.
