【摘要】 针对全复材无人机结构设计特点,详细阐述了整机设计流程。研究了CATIA参数化关联方法和以"布局草图"为核心的自顶向下的设计,提出了无人机结构的参数化装配体关联设计方法,实现了关联引起的模型变更,从而实现了模型快速修改和调整。以某无人机结构为例,验证了关联设计建模方法的有效性。更多还原

【Abstract】 Based on the characteristics of the composites unmanned aerial vehicle(UAV) structure, the whole design process is described in detail. According to the studying of CATIA parameterization correlation method and the top-down design with the core of "layout sketch", parameterization assembly correlation design method of UAV structure is proposed. Model rapid adjustment will be realized on it. Finally the effectiveness of the modeling method is verified by an example of an UAV structure.更多还原
