Abstract

On the basis of geometrical characteristic of the mirco/nano-transmission platform(MNTP), its kinematics model and input/output motion are established by the theory of coordinate transformation. The stiffness model was derived using elasto-dynamics and Lagrange equation. In terms of ANSYS, the output displacement and stiffness of different degrees of freedom(DOF) was simulated. Actual output displacement about x axis and stiffness along z axis were obtained by experimental testing, the results of them obtained by theoretical computation, ANSYS simulation and testing were compared. A good agreement was achieved, which shows that the kinematics model, stiffness model, the design principle and experiments of the MNTP are correct.
