The invention belongs to the technical field of helicopter test flight test, and particularly relates to a civil helicopter ground combined test bench which at least comprises a testing machine, a bench, a testing system, an emergency parking system and a safety monitoring system. The testing machine and the rack are connected through bolts at a mooring point of a frame 1 at the front part of the testing machine, outer flanges at the upper parts of a frame 4, a frame 5 and a frame 6, a newly-added joint at the tail part, an on-board connecting joint of a nose landing gear and a mounting beam of a main landing gear; the test system carries out acquisition, on-line and post-analysis, real-time display and monitoring, alarm and data storage on test signals. The emergency parking system is used for realizing emergency parking in the test process; the safety monitoring system records a test site in real time and monitors the testing machine and the rack in real time at the same time. By adopting the test bench provided by the invention, the working capability, the coordination capability and the matching performance of the transmission part and each system of the helicopter are effectively examined.

    本发明属于直升机试验试飞技术领域,具体涉及一种民用直升机地面联合试验台,所述试验台至少包括:试验机、台架、测试系统、应急停车系统、安全监控系统;所述试验机与台架在试验机前部1框系留点、4框和5框和6框上部外凸缘、尾部新增接头、前起落架机上连接接头、主起落架安装梁处通过螺栓连接;所述测试系统对试验测试信号进行采集、在线及事后分析、实时显示及监控、报警及数据存盘;所述应急停车系统用于实现试验过程中的紧急停车;所述安全监控系统对试验现场进行实时记录同时对试验机与台架进行实时监控。采用本发明提出的试验台有效考核了直升机传动部件和各系统的工作能力、协调能力和匹配性。
