【摘要】 采用面向对象的建模方法,根据独立性原则和物理划分原则对实际的发动机系统进行了模块化划分,采用物理系统建模语言Modelica建立了发动机部件模型库。通过连接模型库中的部件,建立了单缸发动机模型;然后,根据发火间隔和顺序,建立了某4缸汽油机模型,并进行了发动机性能仿真。更多还原

【Abstract】 According to the principle of independence and physical integrality, an object-oriented modeling approach has been adopted using Modelica/Dymola as programming environment. The library of engine component is set up. Then following reality constituent of engine and connecting component, a single cylinder engine has been created, though fire interval and fire order, a control-oriented four cylinders engine is build, performance of engine is simulated and researched.更多还原
