[Abstract]:According to the structural characteristics and mechanical characteristics, a composite main bearing beam structure was developed. The layer design of the main beam is given, and the forming process is described in detail. The finite element analysis model of the main beam is established based on MSC.Patran/Nastran. The static strength of the main beam under multistage load is analyzed by linear solver, and the results of strain and displacement are given. At the same time, the strength test scheme is designed, the static strength test of the main beam structure is carried out, the information of strain and displacement is collected, and the response of the structure is determined. The results show that the full composite main bearing beam structure meets the requirements of strength design and provides the basis for the application of composite material to the main bearing structure.
