The invention belongs to the technical field of helicopters, and provides a helicopter tail rotor control steel cable fatigue test platform which comprises a rack (12), a driving device (4) and a variable loading device (10) are arranged at the two ends of the rack (12) respectively, a front tested piece is arranged on the driving device (4), a control chain (9) is arranged on the variable loadingdevice (10), and a rear tested piece is connected to the control chain (9). And the front tested piece and the rear tested piece respectively penetrate through a front guide mechanism (5) and a rearguide mechanism and then are connected through a resistance strain sensor (6). The test platform reproduces the installation mode, the motion trail and the working state of the test piece on the helicopter in an equal proportion of 1: 1 according to the arrangement trend of the tail rotor control steel cable on the helicopter, so that the installation service life of the test piece can be accurately calculated, and the safe service life of the tail rotor control steel cable of the helicopter is ensured to the maximum extent; the over-life use risk is reduced; in addition, the same test of eight finished tail rotor control steel cables can be realized simultaneously, and the fatigue test efficiency of the tail rotor control steel cables is improved.
Description
technical field [0001] The invention belongs to the technical field of helicopters, and relates to a cable fatigue test platform, in particular to a helicopter tail rotor control cable fatigue test platform. Background technique [0002] The helicopter tail rotor control cable fatigue test platform is a special equipment for verifying the bending fatigue performance of the Mi-17 series helicopter tail rotor control cable fatigue performance. At present, the existing steel cable fatigue test equipment mainly focuses on the fatigue life test of steel wire ropes used in elevators, cranes and mines. Tighter wheels and multiple guide wheels realize the simulation of the forward and reverse combined bending state of the steel wire rope in the elevator; Chinese patent ZL 201010602411. Realize the fatigue life measurement of steel wire rope. The test principle of this kind of test equipment is that the motor drives the driving wheel to rotate a certain arc, and the driving wheel d...
