摘　　要：针对目前注射成型与模具结构分析分别采用相互独立的网格,二者的分析数据无法实现相互无缝输入,导致成型与模具一体化分析边界条件加载存在困难的问题,提出了统一网格的概念,并基于APDL参数化语言给出了统一网格生成的技术与方法,实现了成型分析与结构分析在互为边界上网格节点的一一对应,达到了数据相互无缝输入的目的。该技术解决了在真实成型压力或温度作用下开展模具变形分析面临的网格匹配及数据共享难题,具有极强的应用价值。At present, the injection molding analysis and the mold structural analysis respectively employ the irrelated mesh. Their analysis results can not be directly imported mutually, which leads to the load of boundary condition having much obstacles and difficulty in the integration analysis. In order to conquer the problem, the concept of uniform mesh is presented, and the method and technology of uniform generation based on the APDL are studied. The technology realizes the one-to-one matching of the mesh nodes on the mutual boundary of the molding and structural analysis, and achieves the goal of the data sharing. This technology solves the prob- lem of mesh matching and data sharing for the mold deformation prediction under the load of the real molding pressure or temperature, and possesses great application value.
