Abstract

The invention discloses an aviation oven control sensor positioning method and device, equipment and a medium, and the method comprises the following steps: extracting geometric features of an oven, and constructing a three-dimensional geometric model of the oven according to the geometric features; importing the three-dimensional geometric model into simulation software, inputting material parameters of the oven, and performing grid division on the three-dimensional geometric model of the oven; simplifying a heat exchange mode of the oven after grid division, and determining parameters of hot air flow; taking parameters of the hot air flow as boundary conditions, and inputting the parameters into simulation software; inputting a preset heating condition according to the actual production condition; wherein the heating condition is that heating is performed firstly and then heat preservation is performed; obtaining a temperature field distribution model of the oven in a heat preservation state under the heating condition; according to the temperature field distribution model, determining the position point in the overall temperature field median area, and the method has the advantage that the installation position of the control sensor in the drying oven can be accurately and efficiently determined.

Description

technical field [0001] The present application relates to the technical field of oven temperature testing, in particular to a positioning method, device, equipment and medium for an aviation oven control sensor. Background technique [0002] The oven is an important equipment in the thermal processing process of aerospace material manufacturing. It plays a very important role in eliminating material hydrogen embrittlement, improving coating curing, product thermal aging test, and composite material curing and molding. Temperature uniformity is an important index to measure the temperature performance of the oven. There are many specifications at home and abroad: for example, AMS2750 and CPS8100 have clear requirements for the measurement of temperature uniformity, and the compliance of temperature uniformity test is an important point in the tripartite review such as Nadcap. One of the basis of assessment. With the development of aviation materials in the direction of large...
