Title      Structural design of 2 degree of freedom installation platform for dynamic performance test of transmission gear box 。         

Abstract 2 degree of freedom platform has the advantages of simple structure, stable and reliable work, simple control, can meet the needs of most industrial operations and can reduce the complexity and  cost, simplify the kinematics and dynamics model, therefore, in industrial production and other areas has broad application prospects。 Based on multiple degrees of freedom installation, adjusting platform research and development status, this paper designed  a 2 degree of freedom platform in the test system of transmission gear box installation drive motor and sensor , demanding that the platform can be manual and electric motion along the axis and height direction。This paper focuses on the system drive scheme and structure design analysis, completes the parameter design of drive motor ， transmission system and a guide rail system and the the selection of functional components , completes the design of the platform position and lock tight system , and finally completes the design of structure of experimental platform of 3D solid drawings, and 2D assembly drawing and parts drawing, and analyzes the structural strength and stiffness of the platform 。
