Abstract

The invention relates to the technical field of aircraft strength testing devices, in particular to a testing device applied to a helicopter landing gear drop test, and discloses a device for driving a helicopter wheel to rotate. The device comprises friction wheels (1), a transmission shaft (2), a hydraulic motor (3), gear boxes (4), a rotating shaft (5), a lifting mechanism (6), a winding-unwinding mechanism (7), limiting hoops (8), a servo valve (9), horizontal sliding rails (10), an upright sliding rail (11), a horizontal controller (12), a vertical controller (13), an upright support (14), a horizontal support (15), a base (16), a control system (17) and an installation support (18). The device is not needed to be installed on a testing hanging basket, signal interference in data measured in the test is avoided, and meanwhile the weight of the testing hanging basket is not influenced. The device is light, convenient to use, flexible and convenient to install, the process that a crashing resistant test is carried out after the drop test on a landing gear is finished is not influenced, a testing hanging basket system, a testing system and the like are not needed to be changed, the testing cost is saved, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft strength test devices, and is applied to the test device in the dynamic test of helicopter landing devices. Background technique [0002] The landing gear is an important load-bearing part of the helicopter. A new design of the landing gear needs to pass a series of ground drop tests to adjust the buffer filling parameters and the area and position of the oil hole to improve the buffering efficiency of the landing gear. The test can also verify whether the structural strength and rigidity of the landing gear can meet the design requirements. The ground drop test of the helicopter landing gear needs to simulate the real motion process and force condition of the landing gear during the landing and take-off of the helicopter. One of the most important items is the simulation of the helicopter's three-point horizontal landing speed. Because the speed of the helicopter is not very high when it is rol...
