Abstract

The invention relates to a load measuring device for an elastic bearing of a helicopter rotor system, comprising a measuring base, an X-axis testing mechanism, a Y-axis and a Z-axis bending testing mechanism, a locking mechanism for locking, and a twisting testing mechanism around the X-axis. The measurement base is composed of a detection table base, a rotating shaft, and a large end fixture of the bearing. It is set at the bottom of the equipment, and the X-axis testing mechanism is set on the top of the equipment. Axial and Z-axial bending test mechanisms are respectively arranged in the lower, middle and upper layers of the equipment in sequence from bottom to top along the X-axis axis. The invention realizes the detection of the rigidity characteristics of the elastic bearings of the rotor systems of different types of helicopters on one detection platform, and is good in general use. The detection efficiency and the safety of personnel in the detection process are improved, the detection intensity is reduced, and the elastic bearing can be clamped on one detection platform at one time, and the multi-dimensional direction force (moment) can be loaded and measured at the same time.

Description

Technical field [0001] The invention relates to a loading measurement and analysis device, in particular to a loading measurement device for an elastic bearing of a helicopter rotor system. Background technique [0002] Elastic bearing is one of the three major technologies of the third-generation rotor system. It is an important component of the rotor system. Its rigidity and quality are very important to the safety of the helicopter and directly affect the quality of the helicopter. The stiffness characteristic of elastic bearing is one of the most important characteristics of elastic bearing, so it is necessary to carry out accurate inspection. However, the loading method of the elastic bearing for load measurement should be a multi-dimensional force and moment comprehensive force system, which makes the design technology of the load measurement equipment particularly complicated. At present, there is no equipment that can load and measure the multi-dimensional force and mome...
