Load document handling method and device according to the vehicle of the embodiment of the present invention are described with reference to the accompanying drawings.
Fig. 1 is the process flow diagram of the load document handling method of vehicle according to an embodiment of the invention.
As shown in Figure 1, the load document handling method of vehicle comprises the following steps:
Step S101, arranges operational parameter control and parameter is controlled in output.
In one embodiment of the invention, operational parameter control comprise pending load file title, path, operating mode sum, load applying point is total, solution procedure is total or other operational parameter control.At this, the kind of operational parameter control, quantity are not limited.Wherein, operational parameter control can be used for calculating the position of needed load data in pending load file, if operational parameter control arranges mistake, the position of so needed load data can be by miscount.
In one embodiment of the invention, output is controlled parameter and can be guaranteed that the load data after subsequent treatment is correct, reliable.For example, output control parameter comprises operating mode, load applying point, reference frame numbering or other output control parameter.At this, kind, the quantity of output control parameter are not limited.In addition, parameter is controlled in set output also needs the parameter that will analyze in the analysis software with the later stage to be consistent.For example, the analysis software using when the later stage is Nastran(NASA Structural Analysis) during finite element analysis software, set output is controlled parameter and need to be consistent with the parameter that will analyze in Nastran finite element analysis software.
In addition, in one embodiment of the invention, except operational parameter control and output control parameter are set, according to actual conditions, other control parameter can also be set.For example, in order to meet the needs of vehicle endurance quality design effort or staff's special requirement, other can also be set and control parameter, for example, when export is the form of form, the parameters such as gauge outfit title of export can be set.
Step S102, imports pending load file according to operational parameter control.
Particularly, for example, can import pending load file according to title, the path of the pending load file in operational parameter control.If cannot find pending load file according to operational parameter control, point out error message, now need staff to proofread and revise.
For instance, ADAMS/Car(Automatic Dynamic Analysis of Mechanical Systems/Car, machinery system dynamics automatic analysis/car module) the load file (being pending load file) of multi-simulation software output as shown in Figure 2.ADAMS/Car multi-simulation software is just described for example for convenient, at this, multi-simulation software and pending load file is not limited.
Step S103, judges that whether operational parameter control mates with the property parameters of pending load file.
Particularly, after importing pending load file, whether correct in order to verify the load file of multi-simulation software output, and avoid causing follow-up to the failure of load file processing because staff arranges mistake by operational parameter control, so before processing load file, need to judge that whether operational parameter control mates with the property parameters of pending load file.
More specifically, the property parameters of load file and operational parameter control have definite relation, and for example both may have equal, linear relationship, nonlinear relationship or other relation.Because the load file of different multi-simulation software output is different, at this, the relation between the property parameters of load file and operational parameter control is not limited.Definite relation for property parameters and the operational parameter control of load file will describe in detail in subsequent embodiment.
Step S104, if judgement operational parameter control mates with the property parameters of pending load file, according to operational parameter control extraction load data.
Particularly, if operational parameter control mates with the property parameters of pending load file, according to operational parameter control, extract load data.For example, according to operational parameter control, can calculate the position of needed load data in pending load file, then according to the position of calculating, needed load data be extracted.For example, pending load file as shown in Figure 2, has not only comprised load data in pending load file, has also comprised Word message, can calculate the position of needed load data in pending load file according to operational parameter control.
Step S105, processes the load data of extraction derive.
Particularly, the load data of extraction is processed and derived.For example, can modify to the precision of load data, character length or other attribute, then amended load data can be inserted in the needed format module of analysis software that the later stage need be used.Afterwards the format module file of having inserted load data after processing is derived, in the analysis software for the later stage, the intensity of vehicle component is carried out to simulation analysis, for example, for the Nastran finite element analysis software in later stage.
The load document handling method of the vehicle of the embodiment of the present invention, at least has following beneficial effect: increase work efficiency (1), reduces staff's working strength; (2) avoid staff's subjectivity error, promote work quality, thereby provide good quality assurance for later stage vehicle performance design.
Below in detail introduction how to judge that whether operational parameter control mates with the property parameters of pending load file, and the treatment step when judgement operational parameter control does not mate with the property parameters of pending load file, and introduction concrete steps that the load data of extraction is processed and derived.
Fig. 3 is the process flow diagram of load document handling method of the vehicle of another embodiment of the present invention.
As shown in Figure 3, the load document handling method of vehicle comprises the following steps:
Step S201, arranges operational parameter control and parameter is controlled in output.
Step S202, imports pending load file according to operational parameter control.
Step S203, judge the product of load applying point sum and operating mode sum, pending total columns of load file and determine relation, whether meet first between the character of load title sum three, and judge the ratio, solution procedure sum of total number of load data and the character sum of load title, whether meet second definite relation between total line number three of pending load file.
Wherein, operational parameter control comprises the title of pending load file, the path of pending load file, operating mode sum, load applying point is total, solution procedure is total, the property parameters of pending load file comprises total line number of pending load file, pending total columns of load file, the character of load title is total, total number of load data
Particularly, after importing pending load file, whether correct in order to verify the load file of multi-simulation software output, and avoid causing follow-up to the failure of load file processing because staff arranges mistake by operational parameter control, so before processing load file, need to judge that whether operational parameter control mates with the property parameters of pending load file.
More specifically, the property parameters of load file and operational parameter control have definite relation.For example, owing to comprising load title and load data in load file simultaneously, wherein, load name is called character, and load data is numeral, can utilize the quantity of character, numeral to judge.The load file of the ADAMS/Car multi-simulation software of take output is example, need to judge the product of load applying point sum and operating mode sum, pending total columns of load file and determine relation, whether meet first between the character of load title sum three, and judge the ratio, solution procedure sum of total number of load data and the character sum of load title, whether meet second definite relation between total line number three of pending load file.Wherein, first determine relation, second determine relation can be equate, linear relationship, nonlinear relationship or other relation.Because the load file of different multi-simulation software output is different, at this, to first, do not determine that relation, second definite relation limit.
Step S204, determines relation and second definite relation if judgement meets first, according to operational parameter control, obtains the Data Position of load data in pending load file, and extracts load data according to Data Position.
Particularly, if meeting first, judgement determines relation and second definite relation, can can calculate the position of needed load data in pending load file according to operational parameter control, then according to the position of calculating, needed load data be extracted.
In addition, after step S204, continue execution step S207.
Step S205, does not determine relation and second definite relation, generation error report if judgement meets first.
Particularly, if judgement meets first, determine relation and second definite relation, illustrate that pending load file does not mate with control parameter (parameter is controlled in operational parameter control and output), generation error is reported.For example, when judgement did not meet for the first definite relation, in error reporting, can show that mistake has appearred in load applying point sum and arranging of operating mode sum; When judgement did not meet for the second definite relation, in error reporting, can show that mistake appear in arranging of solution procedure sum.
Step S206, according to error reporting correction operational parameter control.
Particularly, for example, in error reporting, show that arranging of load applying point sum and operating mode sum occurs when wrong, need to check that the load applying point in operational parameter control is total, operating mode is total whether to conform to predefined programme of work, if be not inconsistent, operational parameter control is revised; When judgement did not meet for the second definite relation, in error reporting, show arranging while there is mistake of solution procedure sum, need to check that whether the solution procedure sum in operational parameter control conforms to predefined programme of work, if be not inconsistent, revises operational parameter control; If check and find that arranging of control parameter is errorless, there is mistake in the pending load file that can determine the output of multi-simulation software, need so to revise the pending load file of multi-simulation software output, such as multi-simulation software is exported pending load file again.
In addition, after step S206, continue execution step S202.
Step S207, controls according to operational parameter control and output the load load format template that parameter generates loadmeter grid template and application program.
Particularly, because the object of using the load document handling method of the vehicle of the embodiment of the present invention that pending load file is processed is the endurance quality design and analysis software for the vehicle in later stage, for example can be in finite element analysis software; Or as other simulation analysis in later stage and quoting and reference paper of other work.So, for the user demand in later stage, need to generate the template accordingly with certain format, so that the load data after processing is inserted to format module, be convenient to the use in later stage.More specifically, can control the load load format template that parameter generates loadmeter grid template and application program according to operational parameter control and output, for example, loadmeter lattice file as shown in Figure 4, the load load format of Nastran finite element analysis software as shown in Figure 5.What Fig. 4 and Fig. 5 just did for convenience of description gives an example, the load load format template of loadmeter grid template and application program can be set according to concrete need of work, at this, the load load format template of loadmeter grid template and application program is not limited.
Step S208, carries out pre-service to load data, and respectively load data is inserted to the load load format template of loadmeter grid template and application program and derived.
Particularly, load data is carried out to pre-service.For example, pre-service comprises: the processing of (1) load data precision, retains digital figure place or the quantity of significant figure as selected; (2) load data Overflow handling, during due to some application program loaded load data, the shared number of characters of load data must not be over 8, so, if the significant figure that the numerical value of load data is excessive or retain are too much, will cause data from overflow, therefore for these type of data, can force to utilize scientific notation, within being controlled at 8 characters; (3) extreme value of assumed (specified) load under all operating modes, the work such as the contrast designing for use in later stage vehicle endurance quality, summary.In addition, according to the difference of work requirements, can also to load data, carry out the pre-service of alternate manner, at this, pretreated concrete mode not limited.
More specifically, load data is being carried out after pre-service, pretreated load data is being inserted in the needed format module of analysis software that the later stage need be used.Finally, the format module file of having inserted load data is derived, in the analysis software for the later stage, the intensity of vehicle component is carried out to simulation analysis.
