【摘要】 本文通过把发动机动态系统分解为与时间直接相关和无关的两个子系统的分析方法,探讨了实现发动机动态过程实时仿真的途径,提出了一个船用分轴燃气轮机动态过程实时仿真的方法,该方法可用于大扰动下发动机动态过程的实时仿真。用该方法在Dornier 960仿真机上作了某船用分轴燃气轮机加减速过程的实时仿真。所得的仿真结果实时记录曲线与相应的数字仿真结果完全一致。更多还原

【Abstract】 By using an analytic method consisting in resolving an engine dynamic system into two subsystems, i.e.one, directly time-related and another, time -independent, the authors have made an exploratory study on the feasib- ility of performing a real-time simulation of the engine dynamic process, and proposed a method for the real-time simulation of the dynamic process of split shaft marine gas turbines. By use of the said method a real-time simulation of the speed reducing and increasing process of a split shaft marine gas turbine has been conducted on a simulating machine. The results obtained are in full agreement with those of a numerical simulation method.更多还原
