Modeling of a Chaotic Gyrostat System and Mechanism Analysis of Dynamics Using Force and Energy

Abstract: Incorporating both viscous friction torque and external torque, a mathematical model of a gyrostat system consisting of three rotors and a fixed outer frame is configured. This model is transformed into a Kolmogorov-type system for force analysis. The force field in the gyrostat system includes four different torques—inertial, internal, dissipative, and external. Correspondingly, four different energies are identified and the interconversion of energies is analyzed. The Casimir power being equivalent to the er… Show more

“…In 2001, Kuang et al [9] used Deprit's variable for the first time to investigate chaos in the attitude motion of a gyrostat satellite. A mathematical model for the orbital motion of the attitude dynamics of a gyrostat attached to a satellite was derived by Abtahi [10], whereas Qi et al [11] modeled a chaotic gyrostat system with the aid of energies and external forces. In 2018, Chegini et al [12] assumed two rigid panels were attached with springs in a gyrostat to prove its chaotic nature, whereas they also investigated the existence of chaos in a satellite system [13] moving in an orbital path.…”

“…15 The Melnikov method is used to study chaos on the complex spin-orbit dynamics of gyrostat system, and the heteroclinic bifurcation and chaotic vibrations are proved by numerical methods. 16 Qi and Yang 17 investigate the dynamical behaviors of the gyrostat system by different torques, and a four-wing chaotic attractor is found based on the bifurcation diagram and Lyapunov exponent spectrum.…”
