The study aims to investigate the development and the optimization of a compliant clamp in accuracy high required robotic mechanisms. In this research, a compliant clamp is developed based on flexure hinges to offer the flexibility of movement. Firstly, Solidwork software is used to create a compliant clamp model. Next, a finite element analysis (FEA) is performed using ANSYS software to explore the deformation behavior and stress distribution. The stress and the displacement of the mechanism are two important objective functions considering simultaneously to find the best optimal dimension of flexure hinges. Finally, to improve the strength and increase movement capacity (i.e. how to minimize the stress and maximize the displacement of this mechanism simultaneously), the fuzzy logic reasoning combined with Taguchi method that is proposed in this paper for multiple quality optimization problem. The results reveal that the proposed clamp has the mechanical advantages and the optimal dimension of proposed flexure hinge is the length of 15 mm, the width of 6 mm, and the thickness of 1mm. Therefore, the strength of suggested compliant clamp was improved. It is expected to used in robotic industry and other fields.

Abstract
The study aims to investigate the development and the optimization of a compliant clamp in accuracy high required robotic mechanisms. In this research, a compliant clamp is developed based on flexure hinges to offer the flexibility of movement. Firstly, Solidwork software is used to create a compliant clamp model. Next, a finite element analysis (FEA) is performed using ANSYS software to explore the deformation behavior and stress distribution. The stress and the displacement of the mechanism are two important objective functions considering simultaneously to find the best optimal dimension of flexure hinges. Finally, to improve the strength and increase movement capacity (i.e. how to minimize the stress and maximize the displacement of this mechanism simultaneously), the fuzzy logic reasoning combined with Taguchi method that is proposed in this paper for multiple quality optimization problem. The results reveal that the proposed clamp has the mechanical advantages and the optimal dimension of proposed flexure hinge is the length of 15 mm, the width of 6 mm, and the thickness of 1mm. Therefore, the strength of suggested compliant clamp was improved. It is expected to used in robotic industry and other fields.
