机翼-机身柔顺对接装配及接触力分析方法
Wing-Fuselage Compliant Docking Assembly and Contact Force Analysis Method
【摘要】 在机翼机身数字化对接装配中,由于制造误差、定位误差等因素,装配件在对接前不可避免地存在一定偏差,对接过程中连接结构可能出现磕碰、磨损和变形等现象。为了避免翼身对接装配中遇到上述情况,本文设计了一种五自由度柔顺对接机构,使部件对接过程中遇到干涉时能够柔性适应,根据目标部件的导向顺利完成装配。在此基础上,本文以叉耳式连接结构为研究对象,通过对翼身柔顺对接过程中连接结构的接触力情况进行分析,建立了翼身柔顺对接过程中叉耳式连接结构的接触力预测模型。
【Abstract】 In the digital assembly of the wing-fuselage,due to factors such as manufacturing errors and positioning errors,the assembly parts inevitably have a certain deviation before docking. During the docking process,the connecting structure may experience bumps,wear,and deformation. In order to avoid the abovementioned situation in the wing-fuselage assembly,This paper designs a five-degree-of-freedom compliant docking mechanism. So the components can be flexibly adapted to interference during the docking process.The assembly can be completed smoothly according to the guidance of the target component. On this basis,this paper takes the fork-lug connection structure as the research object,and establishes the contact force prediction model by analyzing the contact force of the connection structure during the wing-body compliant docking process.
