U N I V E R S I T Y O F Structural Design Practices MARYLAND ENAE 483/788D - Principles of Space Systems Design 2 Common Issues in Structural Design 鈥 Static analysis is straightforward; dynamics is tricky. 鈥 Frequency-dependent interactions between subsystems are complex. 鈥 Try to decouple, or isolate, structures or components from each other. 鈥 Structural design is very dependent on the design requirements of other subsystems such as thermal, propulsion, communications, and power. 鈥 Accordingly, aerospac
