本文以带16个叶片的平面盘片结构作为试验件和计算模型,研究了叶片频率失调分布形式、失调幅度,失调阶次对盘片耦合系统的动力特性及受迫振动的影响。实验和计算表明这个力学模型能较全面地反映系统的特性。
In this paper, a planar disk structure with 16 blades is used as a test piece and a calculation model to study the influence of leaf blade frequency misalignment distribution, misalignment amplitude and misalignment on the dynamic characteristics and forced vibration of the disk coupling system. Experiments and calculations show that this mechanical model can reflect the characteristics of the system more fully.
