力平衡加速度表用于测试弹体飞行过程中所感受到的加速度，并根据测得的加速度进行有关方案的计算，具有精度高、量程大的特点。如何在地重力场中模拟弹体飞行时感受到的加速度是仿真的关键问题之一。本文根据平衡加速度表的原理，介绍了如何由电扰动的方式模拟真实的力扰动，提出一种高精度的动态电模拟信号的产生方法，给出半实物仿真系统模型。对系统中占有重要地位的数据通讯作了详细介绍、分析了接口部分的硬件及软件的编程思想．
The force balance accelerometer is used to test the acceleration sensed during the projectile flight and calculate the relevant scheme according to the measured acceleration. It has the characteristics of high precision and large measuring range. How to simulate the acceleration experienced by the projectile flight in the gravitational field is one of the key problems in simulation. According to the principle of balanced accelerometer, this paper introduces how to simulate real force disturbances by means of electrical disturbance, and presents a method of generating dynamic electrical analog signals with high accuracy. The system model of semi-physical simulation is given. Have a detailed introduction to the data communication that occupies an important position in the system, have analyzed the programming thought of hardware and software of interface part.
