| description | 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 <inline-formula><alternatives><math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mi mathvariant="normal">◇</mi><mo stretchy="false">(</mo><mi>R</mi><mo>/</mo><mo>/</mo><mi>R</mi><mo>/</mo><mo>/</mo><mi>R</mi><mo>/</mo><mo>/</mo><mi>R</mi><mo stretchy="false">)</mo><mo>⊥</mo><mi>R</mi><mo>/</mo><mo>/</mo><mi>R</mi></math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/9079DA20-C1AE-48da-AAA0-894F1588485C-M002.jpg"><?fx-imagestate width="33.35866928" height="3.47133350"?></graphic><graphic specific-use="small" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/9079DA20-C1AE-48da-AAA0-894F1588485C-M002c.jpg"><?fx-imagestate width="33.35866928" height="3.47133350"?></graphic></alternatives></inline-formula> branch, and research on the overall motion correlation of the sideward opening aircraft door and its opening mechanism is conducted.

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. |
