实时计算机仿真能进行系统的频率响应试验,并在观察直观显示时能给人以关于系统响应的较好直觉。本文描述了基于准稳态假设的数学模型,以及适于研究系统过渡过程响应的实时数字计算机仿真之形成,也描述了排气温度的热存储效应以及涡轮入口处脉冲流动的影响。通过使用一台模拟计算机作为实时时钟和信号装置而在一分时系统上达到了实时操作。预测与台架试验的过渡过程结果的良好吻合,排烟的预测及实时数字操作,是本项工作的三个鲜明特点。
Real-time computer simulations allow for systematic frequency response testing and give a good intuition about the system’s response when looking at visual displays. This paper describes the mathematical model based on quasi-steady state assumptions and the formation of real-time digital computer simulations suitable for studying the transient response of the system. It also describes the thermal storage effect of the exhaust temperature and the effect of the pulse flow at the turbine inlet. Real-time operation is achieved on a time-sharing system by using an analog computer as a real-time clock and signaling device. The good agreement between the prediction and the results of the bench test transition, the prediction of smoke exhaust and the real-time digital operations are three distinctive features of this work.
