基于推理的大型收获机械变速箱参数化设计

Parametric Design of Large Harvesting Machinery Transmission Gearbox Based on Reasoning

针对传统三维参数化建模软件不易建立结构复杂的大型收获机械变速箱参数化模型的问题,在获取典型收获机械变速箱设计知识的基础上,研究了变速箱参数化设计推理机,提出了一种基于推理的参数化设计方法。在VC++2008环境下,运用Pro/E 5.0中的Pro/TOOLKIT二次开发工具包,开发了基于推理的大型收获机械变速箱参数化设计平台。与传统参数化设计相比,该方法不必考虑在参数化软件中建立零件-部件-产品之间复杂的参数关联关系,可以方便快捷地设计出符合用户要求的变速箱。

In order to solve the problem of low efficiency of transmission design and long development cycle in the traditional design process,the parametric design method was proposed.Based on the typical harvester gearbox design knowledge,the reasoning mechanism for gearbox parametric design was studied.In the environment of VC + + 2008,secondary development Pro/TOOLKIT of Pro/E 5.0 was used.A platform of parametric design of large harvesting machinery transmission based on reasoning was developed.Compared with the traditional parametric design,the proposed method did not need to consider the complex relationship among parameters of parts,components and products in the parameterized software.
