Then, taking the typical Miura-ori tube as an example, an analysis of its mechanical performance under axial compression is conducted to investigate its improvement in buckling control. To explore optimal mechanical performance, a square tube is used as a comparison to study the effects of different geometric parameters on the mechanical properties of the Miura-ori tube. The results indicate that as the length of the parallelogram increases, the internal angle decreases, the thickness decreases, and the crease weakening coefficient decreases, overall buckling control of the slender tube becomes more effective.

Then, the dynamic model of the horizontal drill string system is established during sliding drilling and compound drilling to obtain the corresponding dynamic response characteristics of axial torsional coupled dynamic response. The results show that the rig speed and external load should be increased as appropriate when the SDC is connected to the drill string system, which prevents resonance. A judicious increase of weight on bit can enhance the effectiveness of reducing friction and drag. In contrast, increasing rotary torque has minor impact on the reduction of friction and drag.

Based on these threshold conditions, we systematically investigate the influence of key parameters such as recovery coefficient, excitation amplitude, excitation frequency and damping coefficient on the chaotic characteristics of the system. In particular, we analyze the transformation of system dynamics under different excitation amplitudes, and reveal the key role of excitation amplitude in regulating system stability.

Initially, the slow invariant manifold (SIM) of the system is derived using complexification-averaging and multiple scales methods. The characteristics of saddle-node (SN) bifurcation and Hopf bifurcation at the periodic fixed point are then analyzed, identifying the ranges of stiffness, damping, and other parameters that influence the SMR. Subsequently, the SIM is examined in detail across different timescales, and the amplitude thresholds of external excitation that trigger SMR are derived. Finally, the system's maximum amplitude is optimized to reduce it while ensuring the generation of SMR. A numerical analysis of the energy spectrum near the resonance frequency is also conducted to compare the vibration suppression efficiency between the conventional NES and the bistable NES with nonlinear damping. The results demonstrate that the bistable NES with nonlinear damping effectively lowers the external excitation threshold for SMR, offering a wider threshold range and higher vibration suppression efficiency.
