Multi-axial loading stress corrosion testing equipment

Abstract

The invention discloses multi-axial loading stress corrosion testing equipment. The multi-axial loading stress corrosion testing equipment comprises a top beam, upright columns, a bottom plate, a multi-axial loading device, pulling rods, an in-kettle installing mechanism, an electric pushing rod, a kettle body and a heating furnace, wherein the bottom plate is arranged at the bottom parts of a plurality of upright columns; the top beam is arranged at the top part of the upright columns; the multi-axial loading device, the pulling rods, the in-kettle installing mechanism and the kettle body arearranged among the upright columns from bottom to top; the kettle is arranged in the heating furnace; the electric pushing rod is connected with the heating furnace, and ascending or descending of the heating furnace is realized through transmission of a chain; the bottom parts of the pulling rods are connected with the multi-axial loading device, and the top parts of the pulling rods are connected with a test sample fixedly arranged in the in-kettle installing mechanism; the multi-axial loading device and the in-kettle installing mechanism are both fixedly connected to the upright columns. The multi-axial loading stress corrosion testing equipment disclosed by the invention comprises multiple sets of loading devices, multiple test samples are enabled to be independently controlled, and same or different tests can be carried out at the same time.

Description

technical field [0001] The invention relates to stress corrosion test equipment, in particular to a multiaxial loading stress corrosion test equipment. Background technique [0002] Stress corrosion is the material characteristic of materials under the combined action of external stress and specific corrosive medium environment. Stress corrosion test equipment is specially developed for stress corrosion test. The equipment is equipped with experimental kettle, loading unit, load sensor, displacement sensor, etc. . The experimental kettle can provide a specific medium environment for the material sample, such as high temperature and high pressure ultrapure water medium; the loading unit provides loading stress for the material sample through the pull rod and the clamp. At present, the stress corrosion test equipment generally adopts the form of a test kettle equipped with a loading unit, and only one sample can be loaded for each test, while the general material test needs t...
