The invention belongs to the technical field of helicopter test, and discloses a test device of an undercarriage steering mechanism, which comprises a load device, a pressure-bearing platform and a rotating platform, and is characterized in that the pressure-bearing platform is fixed on the ground, an undercarriage is mounted below the load device, the load device applies a preset undercarriage load to the undercarriage, and the rotating platform is arranged below a steering wheel of the undercarriage; wherein the upper surface of the rotating platform is a plane simulating a helicopter runway, the pressure-bearing platform is a bearing structure of the rotating platform, and the rotating platform can rotate relative to the pressure-bearing platform under the condition that the rotating platform is loaded by an undercarriage. The steering test device is convenient to use, easy to operate and stable and reliable in performance, the steering test of the front/tail undercarriage of the helicopter can be achieved, the steering test of the front/tail undercarriage of each large-size helicopter can be met, nodes of new-type development tasks are guaranteed, the test period is shortened, and the test efficiency is improved.

    本发明属于直升机试验技术领域,公开了一种起落架转向机构的试验装置,包括负载装置、承压平台和转动平台,承压平台固定于地面,起落架安装在负载装置下方,负载装置对起落架施加预设的起落架负载,起落架的转向轮下方是转动平台;其中,转动平台的上表面是模拟直升机跑道的平面,承压平台是转动平台的承载结构,转动平台能够在受到起落架负载的情况下相对于承压平台转动。本发明的转向试验装置使用便捷、操作简单、性能稳定可靠,可实现直升机前/尾起落架的转向试验,可以满足对各大型号直升机前/尾起落架转向试验,保障了新型号研制任务的节点,缩短试验周期,提高试验效率。
