[0002] Oxidation of iron alloys during certain use is one of the important reasons for material failure. Therefore, in the design process of iron components, the oxidation characteristics of the components must be considered. The oxidation characteristics of the material must be considered in the material design or material selection process. Therefore, pre-oxidation simulation of iron components is an important means of designing iron alloy components.

[0003] Existing technical means for simulating the iron-based oxidation process lack consideration of the shape and structure of iron-based components, and only consider the material composition of iron-based alloys. However, structural changes will change the local structure of iron-based components, causing cracks in deformed parts, which will increase the chances of atoms inside the iron-based components coming into contact with air, resulting in reduced antioxidant performance. Existing technologies lack simulation of the dynamic oxidation performance of component structures during the component design stage, making it difficult to achieve precise control of the antioxidant performance of the final designed iron-based components.

[0083] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0084] Reference Figure 1 As shown, a simulation method for an iron-based advanced oxidation process comprises:

[0085] Acquire at least one basic configuration, and build a basic configuration library based on the at least one basic configuration;

[0086] Based on each basic configuration in the basic configuration library, a surface oxidation simulation model corresponding to the basic configuration is established;

[0087] Obtain an iron-based component to be simulated, and decompose the iron-based component to obtain at least one basic component, where the basic component is an integrated component that constitutes the iron-based component and cannot be mechanically disassembled, and the basic component is recorded as a sample component;

[0088] Retrieving at least one basic configuration from the basic configuration library to fit the sample component, and determining at least one basic configuration corresponding to the sample component, which is recorded as a fitting configuration;

[0089] Retrieve the surface oxidation simulation model corresponding to the fitted configuration, substitute the simulation environment parameters, and determine the oxidation state of the surface of the fitted configuration;

[0090] The oxidation states of all the fitting configurations corresponding to the sample component are accumulated to obtain the surface oxidation state of the sample component, and a visualization method is used to simulate and output the surface oxidation state diagram of the sample component.

[0091] This solution establishes a basic configuration library to disassemble and analyze various surface structures that may appear in the design process of iron-based components. When designing iron-based components subsequently, the corresponding basic configurations can be retrieved from the basic configuration library for matching and fitting, and a surface oxidation simulation model corresponding to each surface structure can be established. When simulating the iron-based advanced oxidation process, the changes in the oxidation characteristics of the components caused by the local structural changes of the iron-based components brought about by the surface structure are fully considered, thereby achieving accurate simulation of the oxidation process of iron-based components and precise control of the anti-oxidation performance of iron-based components.

[0092] Reference Figure 2 As shown, obtaining at least one basic configuration and building a basic configuration library based on at least one basic configuration specifically includes:

[0093] Set standard dimensions for basic configurations;

[0094] Acquire at least one iron-based component as a collection component;

[0095] Dividing the surface of the collection component into a plurality of grids according to the basic configuration standard size;

[0096] Extract the surface shape of each grid respectively to obtain several grid configurations corresponding to the acquisition components;

[0097] The same network configurations in all grid configurations are merged with the same items to obtain a number of network configurations that are different from each other, which are recorded as basic configurations;

[0098] All basic configurations are organized into a basic configuration library.

[0099] When building a basic configuration library, it is usually necessary to introduce a variety of component design structures. This process can be imported into the existing mechanical component design library for surface disassembly. It can be understood that the smaller the standard size of the basic configuration, the more refined the disassembled basic configuration, and the more accurate the subsequent configuration fitting.

[0100] Reference Figure 3 As shown, based on each basic configuration in the basic configuration library, a surface oxidation simulation model corresponding to the basic configuration is established, specifically including:

[0101] Determine a reference iron composition ratio;

[0102] A reference thickness is set, and a basic configuration sample with the reference thickness is processed according to the basic configuration based on the reference iron composition ratio;

[0103] Identify at least one factor that affects the oxidation of iron-based surfaces;

[0104] Based on at least one influencing factor affecting iron-based surface oxidation, a surface oxidation simulation model corresponding to the basic configuration is established. The surface oxidation simulation model takes the iron-based surface oxidation rate as output and all influencing factors affecting iron-based surface oxidation as input.

[0105] Reference Figure 4 As shown, based on at least one factor affecting iron-based surface oxidation, establishing a surface oxidation simulation model corresponding to the basic configuration specifically includes:

[0106] Based on the actual environment, determine the parameter variation range of each factor affecting the surface oxidation of the iron system;

[0107] uniformly or non-uniformly taking a number of sample values ​​within the parameter variation range of the factors affecting the iron surface oxidation, and establishing a sample value set corresponding to each factor affecting the iron surface oxidation;

[0108] Select and combine values ​​from each sample value set corresponding to each factor affecting the surface oxidation of the iron system to obtain several groups of test sample parameter groups;

[0109] The rate of change of the oxidation depth of the iron surface of the basic configuration sample under each set of test sample parameter groups is tested in the test box respectively;

[0110] Test and determine the influence coefficient of each factor affecting iron surface oxidation on the rate of change of iron surface oxidation depth;

[0111] A surface oxidation simulation model is established based on the influence coefficient of each factor affecting iron surface oxidation on the rate of change of iron surface oxidation depth and the rate of change of iron surface oxidation depth of all test sample parameter groups corresponding to the basic configuration samples;

[0112] The surface oxidation simulation model is as follows:

[0113]

[0114] Where, V9c1…c i …c m ) is the surface oxidation rate of iron system, (c1…c i …c m is the actual parameter value of all factors affecting iron surface oxidation, c i is the actual parameter value of the i-th factor affecting the surface oxidation of the iron system, m is the total number of factors affecting the surface oxidation of the iron system, is the sample value set corresponding to the i-th factor affecting the surface oxidation of iron system that is greater than c i And with c i The closest sample value, is the sample value set corresponding to the i-th factor affecting the surface oxidation of iron system that is less than c i And with c i The closest sample value, V up For the test sample parameter group Corresponding rate of change of oxidation depth of iron surface, V down For the test sample parameter group The corresponding rate of change of the oxidation depth on the iron system surface is the influence coefficient of the i-th factor affecting the oxidation on the iron system surface on the rate of change of the oxidation depth on the iron system surface.

[0115] Under normal conditions, the oxidation process of iron-based components is jointly affected by multiple factors, and the mutual influence relationship between various factors is very complex. In order to reduce the computing power requirements during model prediction and simplify the oxidation model, this scheme extracts several sample values ​​from the parameter variation range of the influencing factors existing in the real environment, and establishes several test sample parameter groups based on these sample values ​​to pre-test the iron surface oxidation rate. When performing dynamic oxidation simulation, the two groups of test sample parameter groups closest to the actual parameter values ​​are screened out respectively, and the actual parameter values ​​are combined with the comprehensive parameter differences between the two groups of test sample parameter groups to determine the iron surface oxidation rate corresponding to the actual parameter values.

[0116] Among them, it can be understood that for sample value settings, the more sample values ​​are set, the higher the division accuracy is, and the more accurate the oxidation rate calculation is, but the higher the computing power requirement is. Based on this, technicians in this field can set sample values ​​according to hardware conditions in actual applications.

[0117] Reference Figure 5 As shown in the figure, the test determines that the influence coefficient of each factor affecting the iron surface oxidation on the rate of change of the iron surface oxidation depth includes:

[0118] Based on the actual environment, the nominal parameter value of each factor affecting the surface oxidation of the iron system is determined. The nominal parameter value is obtained by setting an environmental collection cycle, continuously and real-time collecting various environmental parameters during the environmental collection cycle, and calculating the average of all parameter values ​​of the collected environmental parameters as the nominal parameter value;

[0119] Set a single influencing factor as the influencing factor to be analyzed;

[0120] Obtain a set of sample values ​​corresponding to the influencing factors to be analyzed;

[0121] Set all other influencing factors in the test box except the influencing factor to be analyzed to their corresponding nominal parameter values;

[0122] The parameter values ​​of the influencing factors to be analyzed in the test box are sequentially set as the sample values ​​in the sample value set, and a test is performed to obtain the rate of change of the oxidation depth of the iron surface of the basic configuration sample;

[0123] By using the correlation calculation formula, the correlation index of the influencing factors to be analyzed on the rate of change of the oxidation depth on the iron surface is calculated;

[0124] Traverse all the factors affecting the iron surface oxidation, and obtain the correlation index of each factor affecting the iron surface oxidation;

[0125] Based on the correlation index of all factors affecting iron surface oxidation, the influence coefficient of each factor affecting iron surface oxidation on the rate of change of iron surface oxidation depth is calculated through the influence coefficient calculation formula;

[0126] The correlation calculation formula is as follows:

[0127]

[0128] Among them, K is the correlation index of the influencing factors to be analyzed for the rate of change of the oxidation depth of the iron surface, x j is the jth sample value in the sample value set corresponding to the influencing factor to be analyzed, L j is the rate of change of the iron surface oxidation depth of the jth sample value in the sample value set corresponding to the influencing factor to be analyzed, S x is the standard deviation of all sample values ​​in the sample value set corresponding to the influencing factor to be analyzed, S L is the standard deviation of the rate of change of the iron surface oxidation depth of all sample values ​​in the sample value set corresponding to the influencing factor to be analyzed, and n is the number of sample values ​​in the sample value set corresponding to the influencing factor to be analyzed;

[0129] The specific calculation formula of the influence coefficient is:

[0130]

[0131] In the formula, K i It is the correlation index of the i-th influencing factor to be analyzed for the rate of change of oxidation depth on the iron surface.

[0132] It is understandable that the degree of correlation between different influencing parameters and the oxidation rate is different. When fitting and analyzing the oxidation rate, changes in influencing parameters with a large degree of correlation will have a greater impact on the oxidation rate of the iron surface. Based on this, this scheme uses the linear correlation under the nominal environment to represent the correlation index of the influencing factors for the rate of change of the oxidation depth of the iron surface, and based on the correlation index of the influencing factors for the rate of change of the oxidation depth of the iron surface, the influence coefficient of each influencing factor affecting the oxidation of the iron surface on the rate of change of the oxidation depth of the iron surface is analyzed and calculated.

[0133] Reference Figure 6 As shown, at least one basic configuration is retrieved from the basic configuration library to fit the sample component, and at least one basic configuration corresponding to the sample component is determined, which is recorded as the fitting configuration and specifically includes:

[0134] Divide the surface of the sample component into a number of grids according to the standard size of the basic configuration, extract the surface shape of each grid of the sample component, and obtain a number of sample configurations;

[0135] Each sample configuration is searched in the basic configuration library to obtain the basic configuration corresponding to the sample configuration, which is recorded as the fitting configuration of the sample configuration;

[0136] Traverse and obtain the fitting configurations of all sample configurations.

[0137] By performing surface decomposition and fitting of the same size on the sample component and traversing, searching and matching with the basic configuration library, the sample component can be split into several fitting configurations that correspond one to one with the basic configuration. Oxidation analysis is performed based on the fitting configuration to obtain the surface oxidation characteristics of the sample component.

[0138] Reference Figure 7 As shown, the surface oxidation simulation model corresponding to the fitting configuration is retrieved, and the simulation environment parameters are substituted to determine the oxidation state of the surface of the fitting configuration. Specifically, the following are included:

[0139] Obtaining the iron component ratio of the sample component, and determining the oxidation ratio of the sample component based on the iron component ratio of the sample component and a reference iron component ratio;

[0140] Retrieve the surface oxidation simulation model corresponding to the fitted configuration, substitute the simulation environment parameters, and obtain the benchmark surface oxidation rate of all sample configurations;

[0141] The surface oxidation rate of the sample configuration is obtained by multiplying the reference surface oxidation rate of the sample configuration by the oxidation ratio of the sample component;

[0142] According to the surface oxidation rate of the sample configuration, the surface oxidation degree of the sample component at different times is determined.

[0143] It is well known to those skilled in the art that the composition of iron-based alloys will affect the oxidation characteristics of iron-based alloys. In the common embodiments of this scheme, the reference iron-based component ratio adopts 40Cr steel. When simulating iron-based alloy components of other compositions, it is only necessary to test and obtain the oxidation performance ratio between the iron-based alloy of the corresponding composition and the iron-based alloy corresponding to the reference iron-based composition. The oxidation performance of different materials is a parameter that can be obtained by those skilled in the art using conventional testing methods, so this scheme will not elaborate on it.
