ABSTRACT:
The experimental study sought to characterize the dynamic modal characteristics of a heliostat to be used at the Sandia operated Solar Thermal Test Facility. Three modal studies were performed. Two studies were conducted of the yoke and one on the facet assembly. During the course of the

test, Power Spectral Density studies were performed using wind-loading and transport environmental data. The modal frequency, damping and stiffness) data is presented. The data obtained through the various studies compares favorably. The data indicates a possible structural modification, and this modification is discussed. Show Less
