A multifunctional undercarriage system comprehensive test bench is used for testing on a hydraulic machine controlled by a microcomputer and comprises the hydraulic machine, a simulation part and an undercarriage system part, the hydraulic machine comprises a cross beam, a sliding block and a base, and the simulation part comprises an undercarriage cabin interface simulation part and a ground simulation part. The undercarriage system part comprises a retractable actuating cylinder, a buffer strut and an airplane wheel assembly, a ground simulation part is mounted on the base, the ground simulation part is in contact with the airplane wheel assembly, an undercarriage cabin interface simulation part is mounted on the sliding block, the airplane wheel assembly is connected with the buffer strut, one end of the retractable actuating cylinder is connected with the undercarriage cabin interface simulation part, and the other end of the retractable actuating cylinder is connected with the airplane wheel assembly. And the other end of the retractable actuating cylinder is connected with the buffer strut. According to the invention, all tests required to be carried out in the final assembly and test flight stages of the undercarriage system can be simulated, the final assembly period can be greatly shortened in batch production models, tests can be carried out in advance in aircraft development tasks, and sufficient data support and improvement period are provided for design.
