Multi-packet whole bladed disks are found in some turbo engines. At the same time, mistuning of blades is inevitable and it will lead to the vibration localization in which vibration energy mainly locates in some blades in the bladed disk system. It can accelerate the high cycle fatigue of the bladed disk. It is critical to search for an efficient way to control the level of vibration localization of the mistuned bladed disk system. Therefore, in this paper, a new method of reducing the vibration localization of the mistuned bladed disk system using bladed packets is studied. A mathematical model is developed in which a coupling stiffness is introduced to describe the coupling relationship due to bladed packets. The effect of bladed packets on the vibration localization of the whole mistuned bladed disk is discussed. The results indicate that the bladed packet can really reduce the degree of the vibration localization of bladed disk. The relationship between the coupling strength of blade to blade and the vibration localization is researched. Moreover, different number of bladed packets of the mistuned bladed disk on the vibration localization of the mistuned bladed disk is investigated for researching the optimal multi-packet structures.

在某些涡轮发动机中可以找到多数据包的全刀片磁盘。同时，叶片的误动是不可避免的，并且将导致振动局部化，在振动局部化中，振动能量主要位于叶片式磁盘系统中的某些叶片中。它可以加速刀片磁盘的高循环疲劳。寻找一种有效的方法来控制雾化刀片式磁盘系统的振动定位水平至关重要。因此，在本文中，研究了一种新的方法来减少使用刀片式数据包的雾化刀片式磁盘系统的振动局部化。建立了数学模型，其中引入了耦合刚度以描述由于有叶片的小包引起的耦合关系。讨论了刀片式包装盒对整个雾化刀片式刀片的振动定位的影响。结果表明，带刀片的包装盒可以真正降低带刀片的磁盘的振动定位程度。研究了叶片与叶片的结合强度与振动局部化之间的关系。此外，研究了有雾化叶片盘的振动叶片定位时不同数量的有雾化叶片盘的叶片包，以研究最佳的多分组结构。
