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.

    一种多功能起落架系统综合试验台,在微机控制的液压机上进行试验,包括液压机、模拟部件及起落架系统件,其中,液压机包括横梁、滑块及底座,模拟部件包括起落架舱接口模拟部件与地面模拟部件,起落架系统件包括收放作动筒、缓冲支柱及机轮组件,底座上安装有地面模拟部件,地面模拟部件与机轮组件接触,滑块上安装有起落架舱接口模拟部件,机轮组件与缓冲支柱连接,收放作动筒一端连接起落架舱接口模拟部件,收放作动筒另一端与缓冲支柱连接。本发明能够模拟起落架系统在总装、试飞阶段所需要进行的所有试验,不仅可在批产型号中大幅缩减总装周期的效果,还可在飞机研制任务中将提前进行试验,为设计提供足够的数据支持以及改进周期。
