HAN Hui, LIU Li. Design of large displacement parallel planar 3-DOF micro-positioning platform[J]. 2021, (6): 73-75. DOI: 10.13873/J.1000-9787(2021)06-0073-03.
Micro positioning platform is a flexible micro positioning system which can realize micro positioning or adjustment precision.A planar three degree of freedom micro-positioning platform with large travel
high stiffness and compact structure is designed through the mutual restriction and interaction of three amplification mechanisms.The driving mode of the platform is piezoelectric
and the piezoelectric ceramic is parallel.Modeling
calculation and simulation analysis of the platform are introduced.The motion range of the platform in X and Y directions is 185.8 μm.The platform is an equilateral triangle with 32 mm side length
which improves the rigidity and stability of the structure.
