Title The Design of Multi-Degree-of-Freedom Installation and  Adjustment Platform  for the Reducer Test System   

Abstract：With the development of mechanization and automation technology, especially  the rapid development of motor and ball screw technology, The installation   platform of the mechanical system is developed by the fixed platform and the manual adjustable platform to the automatic adjustment platform. 

In this paper, a two-degree-of-freedom installation and adjustment platform  is designed for the reducer test system. The platform uses the combination of  electric adjustment and manual adjustment to control the movement in the dir ection of the respective degrees of freedom. The platform can be adjusted in the horizontal direction and the height direction. The platform is designed  with cage symmetrical structure to improve the bearing capacity of the platfo rm. Through the design of the finite element analysis, optimize the platform structure, reduce the installation space，The thesis is outlined as followin g： Chapter 1 briefly introduces the background and significance of the two-degre e-of-freedom installation and adjustment platform design research. Through th e research on the development status of the multi - degree of freedom at home  and abroad, the research on the development status of the platform is combin ed with the design requirements of this subject, and the idea of two - degree

 - of - freedom installation and adjustment platform original scheme is compl eted. Chapter 2 analyzes and determines the purpose and requirements of the two-deg ree-of-freedom installation and adjustment platform, selects the working prin ciple, designs the overall transmission scheme, analyzes and compares the fea sible transmission scheme, determines the optimal transmission scheme and des igns the overall arrangement. Chapter 3, calculate and determine the main dimensions, drawing three-dimensi onal parts and assembly drawings. Chapter 4，Finite element analysis of key parts and two degrees of freedom in stallation and adjustment platform. Chapter 5 summarizes the full text and presents the next step of the work out look.
