Summary
Vibration
is a common phenomenon in nature, which can bring many benefits to human
beings, but also brings harm. Beneficial vibrations can be converted into other
forms of usable energy, produce beautiful notes, transmit signals, etc., which
will bring great benefits to the improvement of human living standards and the
development of military technology. However, when the vibration exceeds a
certain limit, it will cause damage to human health and facilities, making the
instrument and equipment unable to work normally. For example, advanced
aircraft such as artificial earth satellites, unmanned aerial vehicles, manned
spacecraft, space probes, armed helicopters, strategic missiles, etc., have a serious
hazard to the stability of the aircraft system due to the vibration and noise
caused by the complex external environment. This makes the system unable to
realize the effective positioning of the target during the flight, and the
anti-jamming efficiency is poor. Converting these harmful vibrations into
energy can not only eliminate harmful vibrations to protect equipment, but also
capture energy to power microelectronic devices.

Abstract In this paper, the response properties of galloping energy harvesters under bounded random parameter excitation
are studied theoretically. The first-order approximate solution of the galloping energy harvester is derived by
applying the multi-scales method. The expression for the largest Lyapunov exponent that determines the trivial
solution is derived, and the corresponding simulation diagrams, including the largest Lyapunov exponent diagrams
and time domain diagrams, verify our results. Then the steady-state response moments of the nontrivial solution
are studied using the moment method, and the analytical expressions for the first-order and second-order moments
of the voltage amplitude are obtained, respectively. The corresponding…

Abstract The chaotic motion behavior of the rectangular conductive thin plate that is simply supported on four sides by
airflow and mechanical external excitation in a magnetic field is studied. According to Kirchhoff ’s thin plate theory,
considering geometric nonlinearity and using the principle of virtual work, the nonlinear motion partial differential
