基于UG的汽车覆盖件检具基座结构分析

Structure Analysis of Fixture Base of Automobile Cover Parts Based on UG

为了提高汽车覆盖件精度,解决检具基座的变形问题,对检具基座进行了结构分析。在采集现场检具基座变形数据的基础上,利用UG建模模块进行基座实体建模。结合检具的实际工况给出边界条件,划分有限元网格和加载载荷,进行结构分析并获得了基座的位移和应力云图,反映出了检具在实际工况中的应力场分布规律。

In order to improve the precision of automobile covering parts, resolve the deformation problems of fixture base, the structure of fixture base is analyzed. Based on collecting the site deformation data of fixture base, model of base entity is builded by UG modeling module. Combined with the actual working condition of the fixtures, structure analysis for the base by giving boundary conditions,dividing the finite element mesh and loading load, then gets convectives of displacement, strain and stress, it reflects the stress distribution rule of fixture in real working.
