- Synergistic Design of Passive Damping and Metal Matrix Composites
- Description
- Advanced materials, such as Metal Matrix Composites, offer significant improvements in the areas of stiffness, weight, and thermal stability over most conventional materials. To further enhance the benefits afforded by these materials, integration of a passive damping concept should occupy a prominent place in the structural design process as early as feasible. To prove this synergistic approach, a simplified version of a flight-ready spacecraft attitude sensor platform has been chosen. Ultimately, two such platforms will be built, tested, and contrasted in several ways to demonstrate the performance improvements which are possible through this integrated approach. One structure will be fabricated using conventional materials and fabrication techniques, while the other will combine Metal Matrix Composite panels with a constrained-layer viscoelastic damping treatment. This paper describes the requirements, history, and design of the passively damped structure, and introduces plans for future testing and validation of analytical models.

- Abstract
- Advanced materials, such as Metal Matrix Composites, offer significant improvements in the areas of stiffness, weight, and thermal stability over most conventional materials. To further enhance the benefits afforded by these materials, integration of a passive damping concept should occupy a prominent place in the structural design process as early as feasible. To prove this synergistic approach, a simplified version of a flight-ready spacecraft attitude sensor platform has been chosen. Ultimately, two such platforms will be built, tested, and contrasted in several ways to demonstrate the performance improvements which are possible through this integrated approach. One structure will be fabricated using conventional materials and fabrication techniques, while the other will combine Metal Matrix Composite panels with a constrained-layer viscoelastic damping treatment. This paper describes the requirements, history, and design of the passively damped structure, and introduces plans for future testing and validation of analytical models.
