The three-axis simulation turntable as a key loop simulation and test equipment in areas such as aviation, aerospace , plays an extremely important role in the development process of the aircraft . Three-axis simulation turntable performance is directly related to the reliability and confidence of simulation and testing laboratories , to ensure that the basis of models of aviation, aerospace and weapon system accuracy and performance . Therefore , the research and manufacture of three-axis motion simulator is of great significance for the development of the aerospace industry and national defense construction . This article focuses on the structure of the the mechanical body 's three - axis simulation turntable design and kinetic studies , the first three-axis simulation turntable main load calculation method , including the calculation of inertial load , the friction load calculation , calculation of the gravity loads and loads of comprehensive . Study of the principles and methods of selection of drive components and drive way , in which the hydraulic drive with motor drive , direct drive and indirect drive compared , DC servo motors , AC servo motors , torque motors , stepper motors , synchronous motor characteristics were compared , and pointed out that the selection method . Elaborated the mechanical structure of the turntable and the measures taken in order to guarantee the three-axis simulation turntable of the performance indicators in the design and workmanship . Also studied the common factors that affect the accuracy of simulation of three-axis simulation turntable : pointing error rate stability error , amplitude and phase errors , according to the conclusions of the error analysis , pointed out that the design, manufacture , assembly, three-axis simulation table should do 4:00 considerations . Then three-dimensional solid model of a three-axis motion simulator established with CATLA software and motion simulation proved that there is no interference at three frames movement , good movement . Kinetic equation has also established a three-axis motion simulator , three-axis simulation turntable dynamics simulation analysis using ADAMS software , focusing on the motor output torque simulation analysis . Finally , theoretical analysis of the dynamics of the three-axis motion simulator coupling , the simulation analysis of the dynamic coupling between the role of the three-axis simulation turntable using ADAMS software , gives a comparison of selected results of the simulation results with the calculated results and the actual design and optimize the design proposal .
