Abstract
The compliant hinge is a crucial component of compliant mechanisms, transmitting motion and force through the elastic deformation of the compliant element. It offers advantages such as frictionless, gapless, lubrication-free operation, low cost, and lightweight precision, making it highly desirable for high-resolution and high-precision micro and nano motions. However, conventional compliant hinges have the drawback of axial drift, which hinders precise control of axial motion. We designed a passive-compliant hinge with zero axial drift, no assembly required, and both large travel and integration characteristics to address this issue. Our approach involved modeling the compliance, mechanics, and simulation analysis of the critical structure of the compliant hinge, followed by optimization of the structural parameters. We then performed performance modeling of the compliant elements of the hinge concerning the design parameters and range of motion. Finally, we comprehensively evaluated the optimized structure based on performance indexes of the compliant hinge, yielding superior design results.
