In-situ loading device for energy-resolved neutron imaging spectrometer

Abstract

This invention discloses an in-situ loading device for an energy-resolved neutron imaging spectrometer, comprising a power and transmission assembly, a tensioning frame assembly, a displacement sensor assembly, a force sensor assembly, a sample rotation mechanism, a sample clamping and heating mechanism, a vertical flipping mechanism for the tensioning frame, and a swinging mechanism for the tensioning frame. The device is driven by a torque motor, which, after a 180° reversal of the gear pair, drives a worm gear to rotate. This, in turn, drives two sets of worm wheels on both sides of the worm gear to rotate, which in turn drives two sets of bidirectional lead screws to rotate. This causes the nuts of the two sets of bidirectional lead screws to be synchronously stretched along the axial direction of the sample. A strain gauge force sensor and a grating ruler displacement sensor are used to monitor the force and displacement during the stretching process. The sample is heated by electrical heating, maintaining the sample temperature between 25℃ and 1400℃, and a colorimeter is used for temperature monitoring and control.

Description

Technical Field

[0001] This invention relates to the field of precision scientific instrument technology, and in particular to an in-situ loading device for an energy-resolved neutron imaging spectrometer based on a spallation neutron source. Background Technology

[0002] Key hot-end components of aerospace engines introduce complex three-dimensional macroscopic residual stress fields during thermal processing / heat treatment. Under service conditions such as thermal cycling / shock and high / low cycle alternating loads, the superposition of the macroscopic residual stress field and the service load causes a redistribution of the three-dimensional stress field, easily leading to localized stress concentration and inducing microscopic damage to the material. For the past two decades, the problem of residual stress during the fabrication process has received widespread attention from researchers. However, due to the destructive nature or insufficient penetration of laboratory measurement methods, it is difficult to meet the measurement needs of three-dimensional, multi-scale stress in engineering components, resulting in a lack of a crucial residual stress assessment step in the entire production process. In recent years, the construction and routine operation of large-scale neutron scientific facilities in China have made it possible to accurately measure the three-dimensional residual stress distribution of key engineering components. The energy-resolved neutron imaging spectrometer at the China Spallation Neutron Source is the only neutron imaging spectrometer in China that combines high-resolution imaging and diffraction. It can detect structural information several centimeters deep within materials and devices and possesses various characterization methods. However, no high-temperature-stress coupled loading testing device for this spectrometer has been reported, which greatly restricts its measurement applications. Developing a mechanical loading device with high-temperature loading capability for energy-resolved neutron imaging spectrometers will help to conduct in-depth research on the damage evolution mechanism of advanced materials under service conditions. It can provide important support for the research and development and performance testing of key materials in important fields such as aerospace and national defense in my country, and has significant scientific significance and application value.
