Comparison of Structural Performance of One- and Two-Bay Rotary Joints for TrussApplications

摘要

The structural performance of one- and two-bay large-diameter discrete-bearingrotary joints was addressed for application to truss-beam structures such as the Space Station Freedom. Finite element analyses are performed to determine values for rotary joint parameters that give the same bending vibration frequency as the parent truss beam. The structural masses and maximum internal loads of these joints are compared to determine their relative structural efficiency. Results
