登机舱门作为大型客机的一个重要部件,其运动状态和运动模式分析对于舱门功能和运动链设计至关重要。从机器人机构拓扑综合视角,首次提出将某型侧开式登机舱门开启运动机构抽象为2条SS支路与1条,,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=36500686&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=36500682&type=,33.35866928,3.47133350,支路构成的并联机构,进行了舱门及其开启机构运动关联性研究。基于并联机构方位特征集(POC)理论,分析了侧开式登机舱门开启机构拓扑尺度约束类型特征,揭示了舱门机构提升和旋转运动过程具有1个自由度且选取不同独立元素的两种运动模式,进一步发现舱门运动模式切换的几何约束条件为:铰链臂机构转动副间距与平行杆机构杆长在水平面投影尺寸相等。结合挡块限位的舱门驱动保证几何约束条件恒定,提升了舱门模式切换的确定性及开启过程的稳定性。基于方位特征集进行的侧开式登机舱门开启过程研究为飞机舱门设计提供了新思路。
As an important part of large passenger aircraft, the analysis of motion state and motion mode of passenger doors is very important for the design of door function and motion mechanism. From the viewpoint of topological synthesis of robot mechanism, it is proposed for the first time to abstract the opening motion mechanism of a certain type of the sideward opening aircraft door into a parallel mechanism composed of two SS branches and one ,,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=36500696&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=36500689&type=,33.35866928,3.47133350, branch, and research on the overall motion correlation of the sideward opening aircraft door and its opening mechanism is conducted. Based on the position and orientation characteristic (POC) theory, the topological dimension constraint type characteristics of the sideward opening aircraft door mechanism is analyzed. It reveals that the door mechanism possesses two kinds of motion modes with one degree of freedom and different number of non-independent elements during the lifting and rotating processes. The study finds that the geometric constraint condition of the sideward opening aircraft door motion mode switching is that the rotation pair spacing of hinge arm mechanism is equal to the projection size of the parallel link mechanism length on the horizontal plane. The aircraft door drive combined with limiting stopper ensures the constant geometric constraint conditions, improves the accuracy of door mode switching and the stability of the opening process. Research on the opening process of the sideward opening aircraft door based on POC theory provides a new idea for aircraft door design.
