Problems solved by technology

[0003] According to the usual practice, it is necessary to use one-way actuators with the same number as the number of blades to simulate the applied centrifugal load. Due to the limited space size of the blades, not only will it cause difficulty in installation, but also it is easy to cause asynchronous loading during loading control. Difficult to achieve coordinated application with other types of loads
Therefore, it is difficult to carry out the fatigue life test of such parts smoothly by using the conventional test loading method

Abstract

The invention provides a centrifugal load application system. The system comprises a control device (1), an adjustment device (2) and an output device (3), wherein the control device (1) is used for sending a control command; the adjustment device (2) adjusts an output load according to the command sent by the control device (1); and the output device (3) receives the output load of the adjustment device (2), and synchronously applies multi-directional loads to an inner cavity of a component to be detected. According to the centrifugal load application system, a centrifugal load application cylinder can be easily arranged in the inner cavity of the component to be detected, and the multi-directional synchronous loads can be applied to the inner cavity of the component to be detected. The centrifugal load application system has high load application accuracy, and is convenient to operate and control, and safe and reliable to use.

Description

technical field [0001] The invention relates in particular to a centrifugal load application system. Background technique [0002] The key part of the helicopter tail transmission system - the tail rotor shaft is processed and formed by the electron beam welding of the main shaft and the hub part. In order to test the fatigue life of this type of parts, in addition to applying conventional rotational bending moment, axial force, torque, shear force and other loads to the tail rotor shaft, it is also necessary to apply centrifugal loads. The centrifugal load is generated by the helicopter tail blades, the number is the same as the number of blades, and the circumferential direction is evenly distributed. Due to the complex flight conditions of helicopters, the centrifugal load also changes with different flight conditions. [0003] According to the usual practice, it is necessary to use one-way actuators with the same number as the number of blades to simulate the applied c...
