Three shafts radar simulation turntable is one type of the three shafts turntable . The three shafts radar simulation turntable in this design is mainly used to test a certain type of airborne radar. The simulation turntable has great influence on the reliability and credence of experimentation,so the precision accuracy of a certain type of airborne radar is based on simulation turntable.This paper discusses detailedly the design of mechanical structure of the three shafts radar simulation turntable . Then uses the principle to demonstrate it and do the necessary calculation . At the same time, introduce the principle and structure of measurement components and clutch and other components used in the turntable in brief . This design closely revolves around every targets in design assignment,and spreads out from inner frame to outer frame step by step. The chief content of this paper involves the demonstration of the general structure , the design of the detailed structure and the analysis of error of the turntable. Combining the designing character of the turntable ,this paper emphatically discusses the idea and the process in designing the turntable.
