Abstract

According to a 3-PPSR flexible parallel manipulator with specific structure, through theoretical calculation and finite element analysis of the whole robot, stiffness analysis and modal analysis were made and it was obtained the inherent frequency and vibration mode, which can effectively avoid the occurrence of resonance.
