运用Excite Designer研究某机车柴油机的轴系扭振

EXCITE Designer is used to determine the shaft arrangement in the initial development of the engine, the essential optimization tool of the drive system torsional vibration analysis. Due to its characteristics of fast and reliable operation, is widely used in the design of the motorcycles, automobiles, high-power engine in the world. In this paper, using the software, according the technical documentation provided by the engine manufacturers to simplify the engine shaft as much quality system, build the model and enter the appropriate data to the model parameters, calculate the torsional vibration, amplitude the torsional vibration and stress under the normal conditions, then analyze the engine torsional vibration when the first cylinder flames out. Finally, the torsional vibration is good in normal condition, the amplitude of torsional vibration and stress are bigger easily when the first cylinder flames out. So should avoid this.
