摘要
评述了内燃机曲轴轴系振动研究的力学模型、计算方法、试验方法及近年来的最新研究动向 ,讨论了目前内燃机曲轴轴系振动研究中存在的问题和不足。指出有关曲轴振动与轴承摩擦学的耦合、轴系阻尼系数的精确确定以及非线性振动问题 ,都是曲轴轴系振动研究中有待进一步深入研究的课题。
The researches dealing with the mechanical models,calculating methods and experimental investigations on vibrations of crankshaft system in internal combustion engines are reviewed.The current evolutions in these fields are introduced.The problems and demerits remained in current researches are also discussed.It is proposed that there still exist many subjects which should be involved in further researches,such as the coupling effects between the vibrations of crankshaft and the tribological behaviors of journal bearings,the damping coefficients and non-linear vibrations of crankshaft system.
