The invention discloses a loading device for an empennage strength test, and relates to the technical field of
airplane component strength detection. The device comprises a control box, a test
bed is fixedly installed at the top of the control box, two transposition electric guide rails are fixedly installed at the top of the test
bed, transposition sliding tables are installed at the tops of the transposition electric guide rails in a
driving mode, and the same transposition straight supporting plate is fixedly installed at the tops of the two transposition sliding tables; two symmetrically-arranged tool electric guide rails are fixedly installed on the top of the transposition straight supporting plate. By arranging the loading
assembly, the
bending moment loading hydraulic rod applies a static load to the
bending moment loading plate, so that the
bending moment loading plate has a trend of rotating relative to the main loading plate, and the horizontal
tail to be tested bears pitching bending moment, simulates flight state changing actions such as climbing, flat flying and gliding of an
airplane and the load action borne by the horizontal
tail to be tested; and the horizontal
tail to be tested is subjected to a more complicated strength test, so that the reliability of
test data is ensured.
