摘要

Payload adapters are the structural elements that provide mechanical interface between spacecraft and a launch vehicle (carrier rocket). In this work, new designs of the composite adapters are proposed and analysed. The adapters are made of a carbon fabric/epoxy composite material in the form of truncated conical or polyhedral shells. In these designs, the shells of the adapters have cutouts. The adapters do not have a bottom stiffening ring and are jointed to a launch vehicle at a number of supports. The finite-element models of the adapters were created in MSC Nastran. The buckling analyses were performed for the adapters subjected to axial compressive load and bending moment. The effects of the shell thickness and size of the cut-outs on the critical loads have been investigated. The fundamental axial and transverse vibration frequencies have been calculated for the adapters with the payload attached. These characteristics are used to assess the axial and transverse stiffness of the adapter. The effects of the shell thickness and the size of the cut-outs on the fundamental frequency have been investigated.
