Application of a particle damping technique on wind turbine rotor by filling of 90 percent balls

Abstract

Vibration of wind turbine blade is one of the major important obstacle to increase the capacity of electricity generation. Particle damping technique is introduced in wind turbine blade to check the vibration suppression. Damper is mounted on blade externally. RPM of blade, position of dampers, are the variable parameters used in this parametric study keeping particle size as 9 mm and percentage fill in damper is 90 %. Experimental test is conducted in all the research work. Without damping results are compared with with-damping results and find out the vibration suppression regions.
