Simple harmonic motion is a type of periodic motion that can be seen as being sinusoidal in time, as the restoring force is directly proportional to the displacement.
When [P.sub.1] = 1000 Pa, Figure 8 shows periodic motion of the honeycomb sandwich plate.
It can be observed that periodic motion and chaotic motion appear in the vibration of the blade.
The boundaries are marked by yellow in Figure 6 and they conform with the analysis above; for example, the periodic motion (purple) as [l.sub.1] = 3 and p = 0 in Figure 6(a) corresponds to the red curves in Figure 5(a) and the chaotic motion (red) as [xi] = 1.68 and [l.sub.1] = 0 observed in Figure 6(a) matches the phase diagram shown in Figure 3(b), which means that the phenomenon of multistability indeed coexists in the proposed four-wing memristive chaotic system.
Dynamic behaviors can be more clearly observed over a range of parameter values in bifurcation diagrams, which are widely used to describe transitions from periodic motion to chaotic motion in dynamic systems.
In addition, the discretization is a very important tool for analyzing the stability of the periodic motion in the gear system.
The periodic motion of hydraulic actuator is set as 0.5 Hz, 1Hz, 2Hz and 3Hz frequencies.
For the periodic motion in the fluid, it is reasonable to suggest a solution of the form:
Periodic motion plays a very significant role not only in natural science but also in social science such as climate, food supplement, insecticide population, sustainable development.
In 1930, Hartog [1] investigated the nonstick periodic motion of the forced linear oscillator with Coulomb and viscous damping.
For periodic motion, however, the subsequent lines, spokes, or spirals, respectively, in k-space came from different images depicting the subject at subsequent positions in the breathing cycle according to the sinusoidal model.
