| 摘 要： | 建立了柴油机调速的非线性模型并进行了试验研究,以此模型为研究对象,采取了广义频率响应函数方法对柴油机系统动态过程的非线性特性进行了分析,指出了在转速变化范围小于100r/min时,柴油机系统表现出线性特征;在转速变化大于150r/min时,系统的非线性特征较为明显。

| Abstract: | A nonlinear model for simulating the speed regulation process of a naturally aspirated diesel engine has been established to in this paper.The dynamic characteristic of this model has been analyzed as the feature of a diesel engine by means of General Frequency Response Function method. It is concluded that the diesel engine can be looked as a linear system when the speed change of engine is limited within 100 rpm and must be looked as a nonlinear system when its speed change exceed 150 rpm. |
