Abstract

The invention provides a loading head for bending moment and torque synchronous loading without interference, and belongs to the technical field of mechanical devices. The loading head comprises an axis-symmetry torque loading arm installed on the top of a torque loading connector through a nut 2. A loading flange is fixedly installed at the bottom of the torque loading connector. The bottom of the loading flange is used for installing a to-be-detected part. A beam and a T-type beam are fixedly installed on the torque loading connector. The bottom end of the T-type beam is provided with a bending moment loading arm through a bending moment loading connector. The loading head can be applied to a bending moment linkage loading device for torque transmission.

Description

technical field [0001] The invention relates to a loading head which realizes synchronous loading of bending moment and torque without interfering with each other, and belongs to the technical field of mechanical equipment. Background technique [0002] The combined load of bending and torsion is the most common loading situation of parts or components in the fields of aerospace, bridge construction, petrochemical industry, construction machinery and so on. Once the materials and components under service conditions fail, it will cause great harm. The prediction of material properties under torsional and bending loads cannot be solely based on its performance test under single torsional or bending loads, but more needs to be tested on its performance under the conditions of bending and torsion interaction. [0003] Through the search of the existing technical literature, it is found that the stiffness test of parts and components under complex service conditions is still bas...
