提出用IBM-PC微机直接联接光电转速传感器测试发动机飞升曲线。这种方法无须任何硬件扩充就可实时测量并记录发动机动态工作参数进而方便地推算出发动机的数学模型,进行系统仿真或振动分析。由于用软件代替硬件进行测试,修改软件参数即可用于其它各种机械的动态特性分析研究。
It is proposed to test the engine fly-rise curve by using the IBM-PC microcomputer direct photoelectric speed sensor. This method can measure and record the dynamic working parameters of the engine in real time without any hardware expansion, and then easily deduce the mathematical model of the engine and carry out system simulation or vibration analysis. As the software instead of hardware testing, modify the software parameters can be used for a variety of other mechanical dynamic analysis.
