Reduces blade shaft deflection with improved mount design to increase vertical hybrid wind turbine performance

Abstract

Abstract In a vertical hybrid turbine with a shaft bearing holder on one side, it has a shaft deflection problem that interferes with turbine performance. This study aims to improve the design of the turbine holder. The methodology used in this study is to analyse the deflection behaviour of the turbine when rotating. Next in the turbine design review, and the result is to increase the distance of the shaft holder bearings and increase the bearing diameter in the triangular frame. Deflection testing with the help of tracker software that’s able to measure deflection distance in one field when the shaft rotates. The results of the deflection comparison before and after the design improvement show a significant deflection reduction.
