Abstract： The pseudo-rigid-body (PRB) models of bridge type amplification mechanism (BTAM) and micro/nano transmission platform (MNTP) and the bond graph model of the MNTP moving along the coordinate axis were established. The output stiffness of the BTAM and the characteristic equations and state equations of platform moving were deduced by using the compliant mechanism, mechanics of materials, the pseudo-rigid-body (PRB) method, Castigliano’s theorem, the bond graph theory, and the working principle of 6 degrees of freedom the MNTP. By using simulation analysis of Matlab/Simulink, the displacement simulation curve of the MNTP moving along the axis and the flexible hinge angular simulation curve were acquired. The Ansys13.0 was applied to the motion simulation analysis of the platform. The experimental platform was established, and the experimental test was conducted. The Simulink simulation, finite element analysis and experimental results were analyzed, and the result changes were basically the same.  As a result, the correctness and feasibility of the bond graph model of MNTP moving along X/Y were verified, providing a new effective method for the study of flexible mechanism.
