Abstract
Compliant mechanism has the advantages of compact structure, high precision and easy miniaturization. It has been widely used in the fields of robotics, precision engineering, bio-engineering and so on. In this work, a six degrees of freedom hybrid curved beam spatial compliance mechanism is proposed. The spatial six degrees of freedom are realized by means of series-parallel combination of curved beam compliant elements. The structure consists of an outer base, an inner base, a worktable, driving frame, curved beam compliance elements and piezoelectric ceramic actuators. The working principle of motion in six degrees of freedom is analysed, and statics analysis is carried out to verify the feasibility of the structure.
