基于CAXA的通用桥式起重机箱形梁模块参数化设计

CAXA-based parametric design for box girder module of general-purpose overhead crane

在通用桥式起重机箱形梁设计和开发的过程中,零部件的标准化、通用化和系列化是提高产品设计质量,缩短产品研发周期的有效途径,而基于CAXA三维设计系统的参数化设计与二维绘图相比更能满足制造信息化的要求。在系列化前期设计中,同类型的产品只需要设计1台(套)。当产品需要变更尺寸时,可用极短的时间形成新产品的结构图,并通过三维模型更好、更快、更便捷地找出干涉部件并给予及时修改。

During the design and development of the box girder of general-purpose overhead cranes,standardization, universalization,and serialization are the effective ways to improve the product design quality and shorten the product R＆amp;D cycle.Compared to 2D drawing,the CAXA-based parametric design of the 3D design system is can better meet the manu-facturing requirements.During the preliminary serial design,only one set is required for the same kind of products.In case of size change,the structural drawing of the new product can be formed in a short time.The 3D model can be used to find out the interference components in a better,faster,and more convenient way and make timely correction.
