摘　　要：某新型涡轴发动机动力涡轮轴组件是一个带弹性支承和挤压油膜阻尼器的高速柔性转子,对其动力特性和高速动平衡进行试验研究,试验测得轴组件的动力特性,并和计算结果进行对比分析,在此基础上,完成高速动平衡试验。Power turbine shaft assembly of a new - type turbine shaft engine is a flexible rotor with elastic support and squeeze oil film damper, and its dynamic characteristics and high speed dynamic bal ance are researched by experiment in this paper. The dynamic characteristics of the shaft assembly are measured during experiment, and experiment results are analyzed and compared with calculation results. Based on this, high speed dynamic balance experiment of the shaft assembly is carried out and balance effect is ideal.
