Randomized trial investigates a new vibration isolator's performance, suggesting improvements for engineering applications.
Key Points
This research aims to analyze a novel quasi-zero stiffness (QZS) vibration isolator utilizing flexural-torsional buckling to enhance stability and performance.
Simulated force and stiffness characteristics of the isolator under vertical load.
Discussed contributions of cross-sectional dimensions to static characteristics.
Established a dynamic model analyzed using harmonic balanced method and validated by numerical analysis.
The proposed QZS isolator exhibits a linear negative stiffness, with k increasing by 8.6 times from 1 cm to 1.5 cm in cross-sectional width.
Achieved a maximum static bearing capacity of approximately 1000 N at equilibrium, showing superiority over ordinary isolators.
