Design and Analysis of Composite Truss Structure for Space Borne Payloads
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 7
Abstract
Structure of space borne payload serves as load carrying member and is responsible to meet functional and stability requirement of various sensitive instruments. These structures need to survive launch loads and in orbit thermal expansions. When spacecraft is launched, it undergo excessive vibration and inertia forces. Hence designed mechanical structure should be stiff enough and natural frequency of the overall structure should not match with excitation frequency to avoid resonance. In this research work, structure configuration has been developed for payload. Most of the structure components are designed to be made of composite materials to minimize weight. Payload integration module is made from honeycomb sandwich panels and truss is made from carbon fiber reinforced polymer (CFRP) struts and metallic end fittings. Design considerations for laminate layup sequence has been discussed. Target Natural frequency of 50 Hz has been achieved. Structure for a space borne payload is deigned and analyzed in FEA tools.
