Effect of particle damping technique on 1 kW wind turbine blade using 3 mm balls

Abstract

Particle damping technique is first time use for study of vibration suppression in 1 kW wind turbine blade for using change of percentage fill of particles parameter. External container is attached on blade and fills the container using three different percentage changes as 10, 50 and 90 using 3mm spherical ball size. Blade is mounted at root location on electromagnetic shaker and accelerometer is located randomly on blade at 600 mm position from tip of blade. With damping results are compared with without damping and finding out the cases where vibration suppression takes place.
