Description

technical field [0001] The invention belongs to the technical field of aviation assembly, and in particular relates to a force-displacement measuring device and a measuring method. Background technique [0002] The foot control mechanism used by our company's Yunjiu series aircraft is installed behind the frame 2 of the front cabin, where the construction space is narrow and there are many shelters. In the force-displacement measurement process of the foot control mechanism, three people are required to cooperate to complete the force-displacement measurement of the foot control mechanism. In the previous measurement process, one person was required to hold the force measurement tool of the foot control mechanism, one person stepped on the force measurement tool of the foot control mechanism, and one person measured the displacement of the foot control mechanism. When the displacement of the foot-operating mechanism reaches a given value, the person who measures the displac...
