为解决矿用通风机设计周期长,校核判断复杂的技术难题,创新性提出整机设计的正逆向混合建模再设计思想,分析了该设计思想的关键技术并建立了正逆向混合建模再设计框架。应用该设计方法对某风机各零部件进行设计制造,缩短了产品研发设计和加工周期,提高了设计准确度,并为其他产品的研发提供了依据和思路。 In order to solve the technical problems of long design cycle of mining ventilator and check and verify the complicated technical problems, the idea of ​​redesign of forward and reverse hybrid modeling of machine design is put forward creatively. The key technologies of the design idea are analyzed and the forward and reverse hybrid modeling Re-design the framework. This design method is used to design and manufacture the components of a fan, which shortens the period of product R & D and processing, improves the design accuracy and provides the basis and train of thought for the research and development of other products.
