Abstract EN
Thin-walled parts primarily comprise the entire piece of rough machining, and the material removal rate can surpass 95%.
Numerous components with thin-walled structures are preferred in the aerospace industry for their light weight, high strength, and other advantages.
In aerospace thin-walled workpiece machining processes and practical applications, they are excited by the vibration.
The preload changing the modal stiffness of the part is found and this change causes continuous changes in the natural frequency.
Researching on the influence of pretightening force on dynamic characteristics of thin-walled components is highly significant for controlling vibration.
In this study, the typical aviation thin-walled part is the research object.
Finite element numerical simulation and experimental verification are employed to analyze the dynamic characteristics of 7075 aluminum alloy thin-walled plates under different preloads for exploring the relationship between natural frequency and preload.
The relationship is validated by comparative results.
Both the simulation and experimental results show that the natural frequencies of plates increase following the augmentation of the preload.
Thus, this research introduces the method where vibration of aerospace thin-walled parts is reduced by preload.
For practical engineering application, a program showing the relationship between natural frequency and preload is written using Visual Basic language.
