Abstract

The invention relates to a pure torque loading device and method based on the lever principle, can be used for constant-value pure torque stable loading of columnar objects, and aims to solve the problem that the torque analysis result is affected due to the fact that mechanical values such as stretching, compressing and bending are inevitably introduced into an existing torque applying device. The device comprises a force arm supporting assembly and a twisted workpiece mounting assembly, the force arm is fixed to the force arm supporting assembly, one end of a twisted workpiece is installed in a hole with a force arm spreading function, the other end of the twisted workpiece is installed on a positioning block of the twisted workpiece mounting assembly, and the xyz-direction position of the positioning block is adjustable. The pure torque loading device based on the lever principle can apply a pure torque value to a pipeline and a part, other mechanical indexes such as stretching, compression and bending are not brought in, the quantitative and stable torque loading and maintaining functions are achieved, a new torque loading thought can be provided for most objects needing torqueloading, and reliable technical guarantee is provided for product development.

Description

technical field [0001] The invention relates to a torque loading device, in particular to a pure torque loading device and method based on the principle of leverage, which has the characteristics of wide applicability, simple structure, firmness, and low manufacturing cost, and can be used to stabilize the pure torque of columnar objects. load. Background technique [0002] With the implementation of major aerospace engineering tasks such as space stations, lunar exploration missions, Mars exploration missions, and new-generation launch vehicles, high-density launches have become the norm. Engines are in increasing demand. [0003] In the development process of liquid rocket engines and aeroengines, actual machine testing is one of the main means to verify their performance. During the test, the on-site collection of various dynamic parameters of the test model can effectively grasp its operating status and performance, and provide reliable data support for performance ver...
