Abstract：

This article focuses on the collaborative design of vibration suppression and structural lightweighting in the power system of multi rotor unmanned aerial vehicles. The aim is to achieve a balance between vibration control and weight optimization while ensuring structural strength and stiffness. By analyzing the vibration characteristics of the power system and its impact on flight performance, multiple collaborative design methods including dynamic modeling, modal analysis, topology optimization, and multi material mixing are proposed. This design concept can effectively improve the flight stability and control accuracy of unmanned aerial vehicles, providing support for the development of high-performance unmanned aerial vehicles.
