A computer model with 61 grid points and 85 members was used to predict the structural deformations of all the heliostat structural components from the pedestal/foundation interface to the mirror reflective surfaces. The mirror surface rotations are tabulated. The results indicate the current structural configuration will meet requirements of 1.62 mrad standard deviation for structural deflections of the heliostat subject to 27 mph wind and gravity. These values will be optimized with adjustments that compensate for gravity. Stress analyses are in process on all the heliostat structural components and mechanisms. These are based on the maximum loads (90 mph winds at 10/sup 0/ angle of attack and 50 mph winds with the heliostat in any orientation). The initial calculations on the bar joists and gear drive mechanism components show acceptable safety factors.
