The vehicle part inspection method based on wind noise is applied to CATIA software, and the CATIA software is subjected to secondary development, so that full-automatic inspection of parts influencing the wind noise of the vehicle can be realized.
In one embodiment, as shown in fig. 1, there is provided a wind noise-based vehicle part inspection method, the method comprising:
step S100, generating a standard configuration file corresponding to the part to be tested according to the standardized parameters of the part to be tested.
The standard configuration file comprises identification information of the part to be tested and standard parameters of the part to be tested. The standardized parameters of the part to be tested can be parameters which can minimize wind noise after the part to be tested is assembled on the vehicle based on a large number of experiments, so that a reference standard can be conveniently determined for judging whether the part to be tested meets the standard or not.
Illustratively, the standardized parameters of the part under test include: the name of the part to be measured, the number of the part to be measured in a whole vehicle parts table (Bill of Material, BOM), the section measurement type of the part to be measured, the standard section interception position corresponding to the section measurement type of the part to be measured, the standard section interception mode corresponding to the section measurement type of the part to be measured, the standard parameters corresponding to the section of the part to be measured, and the like.
Step S110, extracting actual design parameters of the part to be tested from the whole vehicle part table according to the identification information of the part to be tested in the standard configuration file, and constructing a simulation model of the part to be tested based on the actual design parameters.
The standard configuration file includes identification information of the part to be tested, and for the part to be tested, the standard configuration file also has specific identification information (such as name, number and the like) in the whole vehicle part table, so that the part to be tested can be directly identified from the whole vehicle part table based on the identification information of the part to be tested in the standard configuration file, the part to be tested related to wind noise can be accurately selected, then actual design parameters of the part to be tested are extracted from the whole vehicle part table, and then the simulation model of the part to be tested is built in CATIA software. Because only the design parameters of the part to be tested related to wind noise are imported into CATIA software, the imported data volume is reduced, and the detection efficiency is greatly improved.
And step S120, carrying out section interception on the simulation model of the part to be tested according to a preset section interception rule to obtain at least one section of the part to be tested.
The section interception rule is preset and corresponds to the standard configuration file, and comprises an interception position, an interception plane and an interception area, and standardized parameters of a section intercepted according to the section interception rule are recorded in the standard configuration file, so that the section interception of a simulation model of a part to be detected is required to be carried out by using the same section interception rule, so that the section of the part to be detected is consistent with the section recorded in the standard configuration file, and the subsequent comparison analysis is facilitated.
And step S130, measuring at least one section of the component to be measured according to a preset measurement rule to obtain a measured section parameter of the component to be measured.
The measurement rules correspond to the standard configuration file, and the measurement mode and the definition of the measured reference surface are consistent with those recorded in the standard configuration file so as to unify the standard, thereby being capable of accurately analyzing and judging the part to be measured.
And step S140, determining whether the part to be tested meets the standard according to the measured section parameters of the part to be tested and the standard parameters of the part to be tested.
Specifically, comparing the measured section parameter of the part to be measured with the standard parameter of the part to be measured, if the error between the measured section parameter of the part to be measured and the standard parameter of the part to be measured is within a set range, judging that the part to be measured meets the standard, otherwise, judging that the part to be measured does not meet the standard.
In this embodiment, first, a standard configuration file corresponding to a part to be tested is generated according to a standardized parameter of the part to be tested, so that before the inspection, an inspection standard of the part to be tested is defined first, and consistency and accuracy of judgment of a subsequent inspection result are ensured. The component to be tested is a component affecting wind noise when the vehicle runs, so that whether the component to be tested meets the standard is checked, the parameter design of the component for reducing the wind noise of the vehicle is of great significance, and whether the wind noise of the vehicle meets the requirement can be judged conveniently at the design stage of the component. And then, according to the identification information of the part to be tested in the standard configuration file, the design parameters corresponding to the part to be tested are found out from the part list of the whole vehicle, so that the screening of the parts is realized, only the design parameters of the part related to wind noise in the part list of the whole vehicle are selected, the number of checked parts is greatly reduced, and the checking efficiency is improved. Then intercepting the simulation model of the part to be tested according to a preset section interception rule to obtain at least one section of the part to be tested, wherein wind noise is mainly caused by friction between the section of the part and air, so that the section of the part needs to be intercepted, and the subsequent wind noise analysis is facilitated. And then measuring at least one section of the component to be measured according to a preset measurement rule to obtain a measured section parameter of the component to be measured, and comparing the measured section parameter of the component to be measured with a standard parameter of the component to be measured to determine whether the component to be measured meets the standard, thereby realizing the inspection of whether wind noise brought by the component to be measured meets the standard. In summary, by adopting the method of the application, whether wind noise brought by the component to be tested reaches the standard or not after the component to be tested is assembled on a vehicle can be automatically checked, the checking efficiency is high, and the checking result is accurate.
In one embodiment, as shown in fig. 2, step S100 generates a standard configuration file corresponding to a part to be tested according to standardized parameters of the part to be tested. Comprising the following steps:
step S200, a standard configuration table is manufactured according to the standardized parameters of the component to be tested.
Specifically, a standard configuration table can be manufactured in advance according to a standardized drawing of the part to be tested, and can be in the form of an EXCEL table, and the identification information of the part in the standard configuration table is consistent with the identification of the part in the whole-vehicle part table, so that the following CATIA software can automatically read design parameters.
Illustratively, the parameters in the standard configuration table may be as shown in Table one below.
Table one, check criteria example table.
Step S210, importing the standard configuration form into a preset program, and converting the standard configuration form into a standard configuration file.
Specifically, the standard configuration file can be generated by importing the prepared standard configuration table into the CATIA program.
In this embodiment, the standard configuration file is generated by making a standard configuration table in advance and importing the standard configuration table into a preset program. Therefore, the inspection standard of the component to be inspected is defined, and the consistency and accuracy of the judgment of the subsequent inspection result are ensured.
In one embodiment, as shown in fig. 3, step S120 performs section interception on a simulation model of a part to be tested according to a preset section interception rule to obtain at least one section of the part to be tested. Comprising the following steps:
and step S300, acquiring section interception parameters.
The section interception parameters comprise an interception position, an interception plane and an interception area.
Illustratively, the section name may be defined in CATIA software, and then the section position, the plane coordinate of interception, and the area size of the intercepted section may be input, so that the section interception of the simulation model of the component to be tested may be implemented. The section interception rule is consistent with interception positions, interception planes and interception areas corresponding to the preset sections in the standard configuration file. For example, when the sealing strip is intercepted, the axis of the sealing strip can be identified and a plurality of points are selected on the axis of the sealing strip at certain intervals as the intercepting positions of the sealing strip due to the intercepting detection according to the axial equidistant of the sealing strip of the vehicle door.
And step S310, carrying out section interception on the simulation model of the part to be detected according to the section interception parameters to obtain at least one section of the part to be detected.
Specifically, according to the planned section interception rule, section interception is carried out on the simulation model of the part to be tested, and then a section file can be obtained. Only one section or a plurality of sections can be cut according to actual needs.
In this embodiment, a section interception rule is predefined, and then, according to the section interception rule, a section interception is performed on a simulation model of a component to be tested to obtain at least one section of the component to be tested, so that the operation of section interception of the simulation model of the component to be tested can be achieved. Because the interception rule is fixed, a plurality of components to be detected of the same type can be intercepted according to the unified rule, and whether the components reach the standard or not can be judged according to the unified standard conveniently.
In one embodiment, as shown in fig. 4, step S130 measures at least one section of the part to be measured according to a preset measurement rule to obtain a measured section parameter of the part to be measured. Comprising the following steps:
step S400, determining the section measurement category corresponding to the part to be measured.
The section measurement categories include a gap category, a face difference category, and a compression amount category.
Specifically, the measurement of the section of the gap is to measure the gap between two sides of the section of the part to be measured, such as the gap between the top cover outer plate and the back door, and the size of the gap has a larger influence on wind noise during the running of the vehicle. The surface difference type section measurement is to measure the height difference of two sides of the section of the part to be measured, such as the height difference between front and rear doors. The section measurement of the compression amount is the degree of interference caused by the compression of two sides of the section of the part to be measured, such as the compression degree between the engine cover and the sealing strips at two sides.
Exemplary gap type measurements are shown in fig. 5, where the gap distance of the parts on both sides of the cross section is measured. The surface difference is measured as shown in fig. 6, and the height difference of the parts on both sides of the cross section is measured.
Step S410, based on the section measurement category corresponding to the component to be measured, the section is measured by adopting the corresponding measurement rule, and the measured section parameter of the component to be measured is obtained.
Specifically, for each section measurement category, a corresponding measurement rule, for example, a rule of a selected reference plane, a rule of a selected reference line, a rule of measurement, and the like, is preset. And measuring according to the set rule to obtain the measured section parameters of the part to be measured.
In this embodiment, the type of the section measurement is first determined, and then the corresponding measurement rule is adopted to measure the section, so as to obtain the measured section parameter of the component to be measured. Thereby realizing the measurement of the section.
In one embodiment, as shown in fig. 7, step S410 measures a section by using a corresponding measurement rule based on a section measurement category corresponding to the part to be measured, to obtain a measured section parameter of the part to be measured.
Comprising the following steps:
in step S700, if the section measurement class is a gap class or a face difference class, corresponding reference surfaces are respectively selected on the contour lines of the components on both sides of the section of the component to be measured, and the minimum distance between the components on both sides of the section of the component to be measured is determined based on the reference surfaces, as the gap value or the face difference value.
Specifically, first, two-dimensional images of the components on both sides of the cross section are generated, then a reference plane or reference line is defined in the two-dimensional images, and then the minimum distance between the components on both sides of the cross section is measured as a gap value or a face difference value. The difference between the gap value and the face difference value is that the directions of defined reference lines or reference planes are different after the section is intercepted. Reference is made to fig. 5 and 6.
Step S710, if the section measurement type is the compression type, determining the reference surface of the sealing strip and the metal plate on each section.
The reference surface of the sealing strip is a tangential surface of an outer contour line of a part where the sealing strip interferes with the metal plate, and the reference surface of the sealing strip is parallel to the reference surface of the metal plate.
Specifically, the compression amount is the degree to which the sealing strip interferes with entering the metal plate. Therefore, the contour line of the part of the sealing strip, which is interfered by the sealing strip and enters the metal plate, is obtained, then the section surface is selected as a reference surface on the part closest to the metal plate in the contour line of the sealing strip, and the section surface is selected as a reference surface on the part closest to the sealing strip. The two reference planes are parallel.
Step S720, determining a compression value according to the minimum distance between the reference surface of the sealing strip and the reference surface of the metal plate.
Specifically, after the reference surface of the sealing strip and the reference surface of the metal plate are selected, the minimum distance between the two reference surfaces is used as the compression amount of the sealing strip.
In this embodiment, for the three types of section measurement, corresponding measurement modes are provided respectively, so as to facilitate unified and standard section measurement of the component to be measured.
In one embodiment, as shown in fig. 8, step S140 determines whether the part to be tested meets the standard according to the measured section parameters of the part to be tested and the standard parameters of the part to be tested. Comprising the following steps:
and step S800, if the measured section parameters of the part to be measured are matched with the standard parameters of the part to be measured, judging that the part to be measured meets the standard, recording the position information of the section of the part to be measured meeting the standard, and capturing the picture of the section of the part to be measured meeting the standard.
Specifically, the measured section parameters of the to-be-measured component are compared with the standard parameters of the to-be-measured component, and whether the measured section parameters are in the corresponding standard ranges is checked. And when the measured section parameters are in the corresponding standard ranges, judging that the component to be measured meets the standards. And then, recording the position information of the section of the part to be tested reaching the standard, and capturing a screenshot to save data.
