Simulation and Experiment Study of Torsional Vibration for a Gasoline Engine Crankshaft System

  • 摘要: 为了研究汽油机曲轴系统扭振特性,以某新型1.8L汽油机为研究对象,首先应用多体动力学软件AVL-EXCITE Designer建立曲轴系统模型,利用三维制图软件得出系统的参数,分析曲轴系统的自由振动与强迫振动;应用CATIA软件和Spectra LAB软件得出减振器的转动惯量及固有频率,从而分析加装减振器后轴系的扭振特性。利用LMS Test.lab噪声振动测量系统进行扭振测试,并对试验测试结果与仿真结果进行对比分析,两者吻合得较好,证明本文提供的仿真方法能有效预测实际发动机轴系扭振情况。
