The invention relates to an aircraft undercarriage shutdown load measuring device and a measuring method, belongs to the technical field of aircraft detection, and solves the problems that the shutdown load cannot be obtained in real time in a multi-point manner, the measuring cost is high, and the precision is poor. The device comprises an undercarriage assembly, a pressure measurement assembly and a data processing/conversion module. The undercarriage assembly is provided with an undercarriage buffer air cavity and a measuring device mounting table; the measuring device mounting table is provided with a mounting table vent hole communicated with the undercarriage buffer air cavity; the pressure measuring assembly is provided with a measuring support and a pressure sensor; the measuring support is provided with a measuring support inner cavity and a support communicating air channel. The undercarriage buffering air cavity can be communicated with the measuring support inner cavity, and the air pressure, measured by the pressure sensor, of the undercarriage buffering air cavity can be converted into the aircraft undercarriage stopping load at the position of the data processing/converting module. The device disclosed by the invention can be integrated on the aircraft landing gear, and the method disclosed by the invention can be used for quickly and accurately obtaining the aircraft landing gear shutdown load in a multi-point manner.
