The Research On Dynamic Of Five Axis Test Table

Test table have been used in many realms, such as aviation, aerospace, weapon and voyage etc. It is important in the reseach of airplane and missile. It can reproduce the flying postures and dynamic characteristics of the aircraft and flying weapon etc. So its development was more and more concerned with the development of aerospace and aviation. Dynamic analysis of the test table is very important as it is the basis of the mechanics design and the test table's control.In this thesis the five axis test table was researched. It was making of two axis test table that simulate the target and three test table that simulate the missile. They are interacted to simulate the dynamic characteristics of the flying weapon. Firstly the paper introduce the research situation of the test table and multi-body mechanics, then the motion of the two axis and three axis systems was analyses respectively. Lagrange method and Roberson-Wittenburg method was used to analysis the dynamic characteristics, establish the dynamics model to two axis and three axis, finally the motion and dynamic equation was simulated in Matlab and draw the simulation curve.
