本文阐述了回转周期结构振动特性分析的有限无法。文中采用扇形厚板元和波传动法,计算了叶轮组合件的振动特性,比较了叶轮组合件与单独叶片及轮盘振动特性的差异,並讨论了叶轮组合件几何参数变化对其振动特性的影响。
In this paper, we describe the finite failure analysis of the vibration characteristics of a rotating periodic structure. In this paper, the vibration characteristics of the impeller assembly are calculated by using the fan-shaped slab element and the wave transmission method. The differences of the vibration characteristics of the impeller assembly with the individual blades and the roulette wheel are also discussed. The vibration characteristics of the impeller assembly are also discussed. influences.
