载人离心机是加速度生理研究的必要设备。近年来为适应高性能飞机特点,国外众多报道在载人离心机上进行模拟空战动作的实验。本所的载人离心机只能作单一的梯形加速度曲线,本研究的目的是用计算机控制载人离心机完成各种加速度模式,实现模拟空战动作。载人离心机的加速度是指离心机吊舱的加速度与其重力加速度的矢量和。其值的大小取决于离心机的臂长和转速,在这些因素中,可以调节的只有其转速。又因为转速和控制电压成正比变化,所以我们用电压控制大电机的调速,并作为闭环反馈送入计算机系统。当电机闭环系统给定电压为零时,系统进入准备状态。控制人员从键盘发出执行指令,转速上升,同时进行数据采集处理,作为判别系统运行状态的依据。该系统软件可连续工作,实时记录,判别动态反馈控制数 Manned centrifuge is the necessary equipment for accelerated physiological studies. In recent years to adapt to the characteristics of high-performance aircraft, many foreign reports in manned centrifuge simulation experiments in air combat action. The Institute of manned centrifuges can only make a single trapezoidal acceleration curve, the purpose of this study is to use computer-controlled manned centrifuge to complete a variety of acceleration modes to simulate air combat movements. The acceleration of a manned centrifuge refers to the vector sum of the acceleration of the centrifuge pod and its acceleration of gravity. The magnitude of the value depends on the arm length and speed of the centrifuge, among these factors, only the speed can be adjusted. And because the speed and control voltage is proportional to the change, so we use the voltage control of large motor speed, and as closed-loop feedback into the computer system. When the motor closed-loop system for a given voltage is zero, the system into the ready state. Control personnel issued from the keyboard to execute instructions, speed up, at the same time data acquisition and processing, as a basis for determining the operating status of the system. The system software can work continuously, real-time record, determine the dynamic feedback control number
