Research on stuck issues and mechanism selection testing methods for civil aircraft cabin doors

As one of the key parts of civil aircrafts, the door mechanism is explicitly required to meet various safety indexes in the airworthiness regulations. During the operation of the door mechanism, it is required to achieve the specified movement requirements while overcoming various external forces. The acquisition of the dynamic performance of the moving components and the detection of deformation and jamming are the key and core technologies for the optimized design and experimental verification of the door.
