本文给出6130型柴油机曲轴动应力的一些分析和测试结果以及在发动机各种基本工况下,曲轴弯曲与扭转应力的变化。特别对主轴承不同心度和平衡重对曲轴应力状况的影响,进行了比较详尽的测试和分析。还引用了一些测试与计算数据,以说明平衡重对主轴承负荷、曲轴扭振以及气缸体动应力和振动的影响。 This paper gives some analysis and test results of dynamic stress of 6130 diesel engine crankshaft and the change of crankshaft bending and torsional stress under various basic engine operating conditions. In particular, the main bearing does not concentricity and balance weight on the crankshaft stress conditions, conducted a more detailed test and analysis. Some test and calculation data are also cited to illustrate the effect of counterweight on main bearing load, crankshaft torsional vibration and dynamic stress and vibration of the cylinder block.
