摘要
曲轴的扭转振动是影响发动机安全运行的重要因素之一,因此曲轴扭转振动是发动机研发过程要解决的重要课题。文章以两款不同的直列四缸发动机为研究对象,用测速齿盘作为发动机扭转振动的测量信号齿盘,介绍了测试齿盘的测试方法,并在发动机台架上进行发动机扭振试验测试,为发动机性能改善提供帮助。
The torsional vibration of crankshaft is one of the main factors promising the safe operation of engine,therefore the torsional vibration of crankshaft is the key issue during the R&D process of engine.In this paper,the torsional vibration of crankshaft in two different inline four-cylinder engines was studied experimentally.A speed measuring tooth disc was employed as the signal disc during the experimental test for the torsional vibration of the engine.The test procedure was introduced and the bench tests of torsional vibration were carried out for both engines.The results could provide some guidance for engine performance improvement.
