Abstract
A type of three-axis electric-driven testing simulator with large load is developed for the simulation and integrated experiment of fire control system on armed helicopter. The testing simulator has the advantages of large load, high torque, high power, high frequency response, wide speed control, high precision and super-low speed. The characteristics and the main technological requirements for the testing simulator are introduced and the schemes of mechanical system and the motor drive system are described. The finite element analysis for the testing simulator body is conducted by using the software ANSYS5.7. With the mathematical model for the testing simulator with large load, the real-time control scheme and the control mode are put forward. VxD (Virtual something device) technique is adopted in the real-time software of upper computer. For the communication protocol in this system, double buffer mechanism of upper and lower computers is proposed. The results indicate that the testing simulator achieves a good performance and high control precision, and the whole control system has a strong robustness. The testing simulator has fulfilled tasks of real-time hardware-in-loop simulation tests of fire control systems for many kinds of armed helicopters.
