The Role of Resonances in Astrodynamical Systems
نویسنده
چکیده
This review intends to highlight the importance of resonances of the orbits of planets and asteroids in our Solar System. Besides the well known 5:2 mean motion resonance between Jupiter and Saturn, we discuss how secular resonances act, where the motions of the longitudes of the perihelia and/or the longitudes of the nodes are involved. Resonances are especially important for the motions of small bodies in the Solar System from the Earth crossing Near Earth Asteroids to the far moving asteroids and comets in the Kuiper belt outside Pluto’s orbit. Briefly we also discuss retrograde orbits in resonances which turn out to be much more stable then prograde ones. The presence and importance of resonances in the dynamics of extrasolar planetary systems is a new exciting field for celestial mechanics.

Vibration Analysis of a Nonlinear System with a Nonlinear Absorber under the Primary and Super-harmonic Resonances (TECHNICAL NOTE)
Abstract In vibratory systems, linear and nonlinear vibration absorbers can be used to suppress the primary and super-harmonic resonance responses. In this paper, the behavior of a nonlinear system with a nonlinear absorber, under the primary and super-harmonic resonances is investigated. The stiffnesses of the main system and the absorber are cubically nonlinear and the dampers are linear. M...
متن کاملAnalyzing the internal resonances and energy exchange between modes of power system considering Frequency – Energy dependence using Pseudo-Arclength and shooting algorithm
The power system nonlinearity and its profound impact on the individual states of power system is first evaluated and the interaction between their constituent modes during the occurrence of internal mode resonance (IMR) is discussed in this paper. A typical dynamical feature of nonlinear systems is the frequency-energy dependence of their states and their corresponding constituent modes which ...

In this paper, we study a new kind of multiphoton resonances in a strongly driven six-level quantum system, where one of its levels is coupled individually with the other two levels that have the constant energy separation E. Near the multiphoton resonance condition, a different behavior for the number of even or odd photons was found qualitatively, which could be explained by considering two c...
متن کاملThe Response of Two-Degree of Freedom Self-Sustained Systems with Quadratic Nonlinearities to a Parametric Excitation (RESEARCH NOTE)
In this study the interaction between self-excited and paramet rically excited oscillations in two-degree-of-freedom systems with quadratic nonlinearities is investigated. The fundamental parametric resonance of the first mode and 3:1 internal resonance is considered, followed by 1:2 internal and parametric resonances of the second mode. The method of multiple time scales is applied to derive f...
