High-temperature tensile experiment device and method

Abstract

The invention discloses a high-temperature tensile experiment device and method. The device comprises a static loading system, a sample clamping system, a sample heating system, a sample pushing system and an image collecting and processing system; the static loading system comprises an universal testing machine, a loading cross beam, a force sensor and a base; the sample sampling system comprisesa lower adapter, a lower clamp, an upper clamp and an upper adapter; the sample heating system comprises a heating furnace body, an observation window, quartz glass located outside the observation window, a sample channel, a heating element, a shielding gas inlet hole and a heating cavity; the sample pushing system comprises a sample clamping head, a guide rail and a controller; the image collecting and processing system comprises a plane mirror, a light source, a video camera, a filter lens and a second computer. A sample can be rapidly heated and warmed, the testing machine can be clamped,and meanwhile the deformation and damage process of the sample under the high-temperature tensile load can be captured.

Description

technical field [0001] The invention relates to the technical field of structural deformation and mechanical experiments, in particular to a high-temperature tensile test device and a method thereof. Background technique [0002] In recent years, with the rapid development of national defense needs and the increase of human exploration of space resources, the competition among major countries in the world in aerospace and aviation technology has become increasingly fierce. Advanced hypersonic vehicles and aero-engines have become the research direction and development hotspot of all countries. , It also reflects the comprehensive national strength of a country. Due to the increasingly high requirements for the performance of hypersonic vehicles and aero-engines, their structures are often faced with harsh service temperature environments. For example: for a hypersonic vehicle, long-term hypersonic flight in the atmosphere, aerodynamic heating will cause the local part of th...
