Title
Evaluation of Damping Concepts for Precision
Mounting Platforms
Description
Conceptual analysis of a damped precision mounting platform with improved thermal and dynamic stability is presented. The use of metal matrix composite materials combined with viscoelastic damping materials results in uniquely stable, lightweight structures. Achievable goals for improved performance of an existing spacecraft precision mounting platform are established. Eight concepts are evaluated and ranked on damping, strength, thermal distortion, instrument mounting, and cost of fabrication. Three designs are selected for detailed quantitative analysis. Results for all three designs indicate performance goals can be met or exceeded. Thermal distortions and dynamic jitter response are both reduced by a factor of 5.
