Abstract

The invention relates to a device and a method for testing tangential rigidity of a junction surface of a wheel disc. The device comprises a universal testing machine, a pull rod rotor, a digital dial gauge I, a digital dial gauge II and a computer, wherein a pressure sensor arranged on the universal testing machine is connected with the computer by a data line; the universal testing machine further comprises a rack; an upper press head is arranged on the top of the rack; the digital dial gauge I and the digital dial gauge II are respectively positioned at two sides of the upper press head; a movable cross beam is arranged in the middle of the rack; two support blocks are arranged on the cross beam at an interval; the pull rod rotor is horizontally erected on the two support blocks; the pull rod rotor is positioned just under the upper press head. After the technical scheme is adopted, the technical problem that a device and a method which are used for testing the tangential rigidity of the junction surface of the wheel disc are lacked in the prior art can be solved.

Description

technical field [0001] The invention relates to a wheel disc of a disc tie rod rotor, in particular to a device and method for testing the tangential stiffness of the joint surface of the wheel disc. Background technique [0002] Disk-type circumferential tie-rod rotors are widely used in the field of gas turbines because of their ease of processing and cooling channel design. The disc-type circumferential tie rod rotor is formed by passing through the multi-stage wheel discs through several circumferential tie rods, and compressing the wheel discs by applying pre-tightening force to the circumferential tie rods. There are a large number of joint surfaces between the wheel discs, so that the mechanical The structure or system has discontinuity, which affects the overall performance of the mechanical system to a large extent, leading to the complexity of the problem. As an important part of the overall stiffness of the mechanical structure of the joint surface, the tangentia...
