Title:
METHOD AND DEVICE FOR DETERMINING WORKING STATE OF CRYOSTAT MODEL
Document Type and Number:
WIPO Patent Application WO/2024/050985
Kind Code:
A1
Abstract:
A method for determining the working state of a cryostat model, comprising: determining a steady-state temperature field of a standard cryostat model and an evaluation temperature field of a cryostat model to be evaluated (S101); determining the temperature average of a first reference comparison channel of the steady-state temperature field as a first reference temperature, and calculating first relative temperature differences respectively between temperature averages of the steady-state temperature field and the first reference temperature (S103); determining the temperature average of a second reference comparison channel of the evaluation temperature field as a second reference temperature, and calculating second relative temperature differences respectively between temperature averages of the evaluation temperature field and the second reference temperature (S104); and comparing temperature data corresponding to the same temperature sensor channels in the steady-state temperature field and the evaluation temperature field, so as to determine the working state of the cryostat model to be evaluated (S105). The working state of a cryostat model having a complex structure is identified on the basis of temperature field comparison in a spatial discrete form, and the method is suitable for temperature field analysis of vehicle-mounted cryostat models of superconducting maglev trains. Also disclosed is a device for determining the working state of a cryostat model.
