一、问题的提出作为力矩电机伺服随动系统的负载——天线以及固定在天线背面的某些高频装置,在随动系统的综合设计、校正及调试过程中,必须求出天线负载的转动惯量 J。伺服系统的天线负载,它是一个非规则物体,而对这类非规则物体的转动惯量计算,没有现成的公式可供工程计算使用。若把天线各部份分别折合成规则几何物体进行转动惯量计算,然后移轴总合出转动惯量这种方法则过于繁琐。为此我们力求寻找一个较为简易可行的途径来解决问题。根据五○二所提供的公式,我们做了实验,解决了天线负载的转动惯量计算,尔后并对现成公式进行推导和分析.
First, the issue put forward As a torque servo motor servo system load - the antenna and the antenna fixed to the back of some high-frequency devices, servo system in the overall design, calibration and debugging process, you must find out the rotation of the antenna load Inertia J. Servo system antenna load, it is an irregular object, and for such non-regular object moment of inertia calculation, there is no ready-made formula for engineering calculations. If the various parts of the antenna are respectively converted into a regular geometric object to calculate the moment of inertia, and then the total amount of moment of inertia of the moving axis method is too complicated. To this end, we strive to find a more simple and feasible way to solve the problem. According to the formula provided by 502, we did experiments to solve the calculation of the moment of inertia of the antenna load, and later deduced and analyzed the existing formula.
