Application of modal analysis technology in the structural design of microwave components
In the structural design of microwave components, the vibration is one of the most important factors which affect the reliability. When the natural frequency of a component is accordant with outer excitation frequency, the resonance will be set up. How to obtain the natural frequency is a difficult task to the engineers. In this paper, some influential factors are discussed. And with the aid of professional software, the method of modal analysis is used to emulate the natural frequencies and the mode shape of microwave components. Based on the simulation, the designers can optimize the structure and get the best project.
