【摘要】：根据结构特点和受力特性,研制了一种全复合材料主承力梁结构。给出了主梁的铺层设计,详述了其成形工艺。基于MSC.Patran/Nastran建立了主梁有限元分析模型,采用线性求解器对多级载荷作用下的主梁进行了静强度分析,给出了结构应变与位移结果。同时设计了强度试验方案,对主梁结构进行了静强度试验验证,采集了应变与位移信息,确定了结构的响应。结果表明,全复合材料主承力梁结构满足强度设计要求,为复合材料应用于主承力结构提供了依据。
[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.
