　　为提高某型直升机飞行模拟器操纵系统操纵力感逼真度，将直升机操纵系统分布参数分段集中化处理，利用最小二乘参数估计法得到其线性模型，并以纵向通道为例建立了杆力-位移模型和电动力伺服加载系统模型。将模型应用于某型直升机飞行模拟器并进行力感试验，试验结果表明，所建立的杆力-位移模型与实装飞机力感特性相吻合，充分证明了杆力-位移模型的有效性，该模型已成功地应用于某型直升机飞行模拟器操纵负荷系统。

To improve the force-sense fidelity of control loading system for a certain type of helicopter flight simulator, the heli-copter distributed system parameters are centralized, and the linear model is built with the Least-Square estimation method (LS). Taking longitudinal channel as an example, the pole force-displacement mathematical model and electro-servo loading system model are built. The model is applied to a type of helicopter and it makes force-sense experimental flight, the results show that force-displacement model meets with the real flight force-sense characteristics and its validity is proved, the model is successfully applied to a type of flight simulator control loading system.
