The invention belongs to the technology of helicopter main landing gear fatigue tests, and relates to a main landing gear three-way loading test device. The main landing gear three-way loading test device can solve the problem that a current test device cannot carry out a three-way loading test on a main landing gear with two tires. The main landing gear three-way loading test device disclosed by the invention comprises a wheel shaft arranged at the bottom end of a vertical buffer support, wherein airplane wheel artificial pieces for simulating helicopter tires are arranged on the rotating shaft; the airplane wheel artificial pieces comprise a first airplane wheel artificial piece and a second airplane wheel artificial piece which are symmetrically arranged on the left side and the right side by taking the axis of the buffer support as the center. The main landing gear three-way loading test device further comprises a first loading piece, a second loading piece and a third loading piece. According to the main landing gear three-way loading test device disclosed by the invention, the design of a three-way loading structure is simplified, the device is simple and practical, and the structure and loaded characteristic of the airplane wheels of the main landing gear with two tires can be simulated more truly and accurately.
