摘　　要：为提高25型铁路客车车体有限元模型前处理效率,通过25型铁路客车车体结构谱系梳理,采用模块化和参数化建模技术构建了25型客车车体模型库;基于HyperMesh软件开发了25型客车车体仿真模板;通过集成25型客车车体模型库和仿真模板开发了25型客车车体参数化仿真系统。该系统可通过模块选配和参数变更快速生成25型客车车体几何模型,通过调用仿真模板快速生成ANSYS和ABAQUS两种求解器所需的有限元模型。应用该系统使25型客车车体有限元模型前处理时间缩短为1周左右,极大提高了有限元模型前处理效率。For raising FEM model pre-processing efficiency of 25 Type passenger train car body, This paper constructs model library of 25 type passenger train car body adopting modularization and parameterization technology through teasing the pedigree of 25 type passenger train car body structure ,and develops simulation template of 25 type passenger train car body basing on HyperMesh; and develops 25 type passenger train car body parameterization simulation system through integrating model library and simulation template of 25 type passenger train car body. This system can construct geometry model of 25 type passenger train car body rapidly through module choice and parameter variation, and construct FEM model for ANSYS and ABAQUS through simulation template rapidly. The FEM pre -processing time of 25 type passenger train car body is shortened to about one week adopting this system, which raises FEM model pre-processing efficiency greatly.
