Linear Static Examination of a Composite Base Structure

Abstract

The base structure of the spacecraft connects the satellite with the launch vehicle and it is the main load bearing member. To satisfy the structural requirements, advanced materials are used commonly to manufacture the mechanical load bearing members. The paper deals with the analysis of the base structure of the spacecraft using a combination of metal with the composite materials like CFRP (Carbon Fiber Reinforced Plastic). Analysis is done for base structure of the spacecraft by varying materials in ANSYS 14.5 for each ring. The variation of the materials is done on the insert ring of the base structure along the height in five different ways. The analysis done suggest that the combination of Ti and CFRP ensures lower deformation and weighed 7.34 kg achieving a mass saving of 35% on the existing structure.
