Structural response analysis of composite fiber blade of small wind power generator turbine blades

In this paper, the vibration response characteristics of small laminated composite wind turbine blades under prestress are studied. By using the simulation software structural mechanics module and modal analysis module, the variation trend of vibration mode and natural frequency of fan blade in standby state and different speed coupling state was explored. The stress distribution law of the composite layer of the blade under multiple prestressing forces is studied. The research in this paper can provide the simulation basis for the structural design of small fan blade vibration response.
