Abstract
The present invention belongs to the technical field of mechanical test devices, and provides a multi-bolt loosening test machine for flange with tension and bending compound loading, which is a test machine researching the anti-looseness properties of bolts by applying tension, bending and torsion compound loading to multi-bolt connection flanges. The multi-bolt loosening test machine for flange with tension and bending compound loading uses a transverse load generated by a three-phase asynchronous motor as a bending load applied to a flange, uses a tension force generated by a hydraulic puller as an axial tension load, is different from the current device that can apply two compound loads to a single bolt, and can apply two compound loads to the multi-bolt connection flanges. The present invention can isolate two compound loads from each other without interference, and display the applied loads in real time.
