Abstract :
Flight motion table is one of the key devices in Hardware in the Loop Simulation (HILS) Test System for guided weapons, research on dynamic frequency index of flight motion table and its influence on simulation results is of far reaching importance. Kinematic model for attitude motion of airframe is built, calculation formula for aerodynamic coefficients is given out based on double variant curve-fitting method, and frequency response characteristics of control system in the missile flight process is obtained. A time-domain index of normalized tracking error is put forward to evaluate the influence of frequency response characteristic for flight motion table on the simulation system, the relational expression between time-domain normalized tracking error and frequency response characteristic of flight motion table is deduced. The simulation results show that with double-ten bandwidth of flight motion table above 3 times of cutoff frequency for control system, normalized tracking error in time domain is less than 5%, which meets the requirement of simulation system.
