Modeling and Simulation of Three-Axle Flight Simulation Table

The three-axle flight simulation motion table is an important instrument and is used widely in the area of national defence and all other relevant industries. Accurate dynamic equations of three-axle motion machine are derived from Lagrange's equations of motion. Considering the equations for brushless electric motor of inner race and the equations for hydraulic servomotors controlled by electro hydraulic servo valves of middle race and outer race, and simplifying the equations under conditions of practice, we present the mathematical model of the table system. Digital simulations are carried out. The model is useful for the analysis, design and compensation of the three-axle motion table
