新疆-X联合收获机CAD系统中割台三维参数化模型的建立与研究

新疆联合机械有限责任公司生产的“新疆-X”型联合收获机是新疆的名牌产品，且于1995年被列为国家重点新产品。为了适应市场需求，缩短系列化新产品的开发周期，大幅度提高劳动生产率，利用CAD中的三维参数化技术是一种有效的手段。要实现参数化设计，参数化模型的建立是关键。该文以新疆-X联合收获机为例，以割台的设计过程为依据，抽取设计过程中关键因素，从设计的角度建立了其割台的三维参数化实体模型（该模型经过部分修改可成为其他类型割台的模型）是实现割台部分参数化设计的理论基础。

Xinjiang-X Combine Header 3D Parametric Modeling in Xinjiang-X Combine CAD System

The Xinjiang-X Combine is the product of Xinjiang United Machine Co.Ltd.,which is a famous product in Xinjiang.In order to accommodate the need in market and enhance the productivity,using the 3D parametric technology is an efficient way. The key of implementation of parametri design is parametric modeling. In this paper the Xinjiang-X Combine Header 3D modeling was established based on Xinjiang-X Combine based on the design of combine header, the application of 3D CAD system and parametric technique in agricultural machine design were researched. It laid the theoretical basis for further establishment of combine header parametric modeling.
