Abstract

The invention relates to a helicopter rotor system elastic bearing load measuring device. The helicopter rotor system elastic bearing load measuring device comprises a measurement base, an X axis direction testing mechanism, a Y axis direction bending testing mechanism, a Z axis direction bending testing mechanism, an alignment locking mechanism and a torsion testing mechanism in the X axis direction. The measurement base is composed of a detecting platform base, a rotating shaft and a bearing large-end clamp and arranged at the bottom of the helicopter rotor system elastic bearing load measuring device. The X axis direction testing mechanism is arranged on the top of the helicopter rotor system elastic bearing load measuring device, and the torsion testing mechanism in the X axis direction, the alignment locking mechanism, the Y axis direction bending testing mechanism and the Z axis bending testing mechanism are correspondingly arranged on the lower layer, the middle layer and the upper layer of the helicopter rotor system elastic bearing load measuring device in sequence from bottom to top along the axis lead in the X direction. Through the helicopter rotor system elastic bearing load measuring device, the rigidity characteristic detection on different models of helicopter rotor system elastic bearings can be performed on one detecting platform, and university is good. The detecting efficiency and the safety of personnel in the detecting process are improved, the detecting strength is reduced, the elastic bearings can be clamped on one detecting platform at a time, and force (torque) in multi-dimensional directions can be loaded and measured.

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 stiffness 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 detection. 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...
