[0046] The embodiment of the present invention solves the technical problem of low efficiency in generating a dynamics simulation model file of a tire system in the prior art by providing a method and a device for generating a dynamics simulation model file of a tire system.

[0047] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] This embodiment is described by taking the multi-body dynamics simulation software as Adams software as an example, but is not limited to Adams software. Adams software provides a front tire dynamics simulation modeling template and a rear tire dynamics simulation modeling template. The existing modeling method is to manually maintain each parameter in the front tire and / or rear tire dynamics simulation modeling template in Adams software, and the parameter maintenance amount is large, resulting in low efficiency in generating tire system dynamics simulation model files.

[0049] The present embodiment finds that each time the front tire and / or rear tire dynamics simulation model file is generated, most of the parameters used for modeling in the front tire and / or rear tire dynamics simulation modeling template are fixed, and only a small number of parameters will change. Therefore, the present embodiment can adopt a method of only maintaining variable parameters instead of fixed parameters when generating the front tire and / or rear tire dynamics simulation model file, thereby improving the efficiency of generating the front tire and rear tire dynamics simulation model files.

[0050] In the front tire and rear tire dynamics simulation modeling templates, different parameters are in different rows. The premise for modeling in this embodiment is to analyze the description of all variable parameters in the template and the row where the variable parameters are located in the modeling template. This embodiment can obtain the description and row number of the variable parameters as shown in Table 1 after analysis. The parameters that will change when establishing the front tire dynamics simulation model include the name of the front tire dynamics simulation modeling template, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body attribute file and contact type, etc. The parameters that will change when establishing the rear tire dynamics simulation model include the name of the rear tire dynamics simulation modeling template, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body attribute file and contact type, etc. Among them, the tire role is front (representing the front tire) or rear (representing the rear tire); the contact type includes handling, 3D and 3D Smooth.

[0051] Table 1

[0052] Serial number Parameter variables Line Number describe 1 Template Name 8 TEMPLATE_NAME=full_pathname+tire_filename 2 Tire Role 10 MINOR_ROLE = 'front' 3 quality 23 MASS=20 4 X moment of inertia 25 IXX=50000 5 Y moment of inertia 26 IYY=50000 6 Z moment of inertia 27 IZZ=10000 7 Tire properties file 31 PROPERTY_FILE = 'xxx.tir' 8 Contact Type 32 CONTACT_TYPE='handling'

[0053] After obtaining the description and row of the variable parameters in Table 1, you can start generating the front tire and / or rear tire dynamics simulation model file.

[0054] In this embodiment, when the front tire and / or rear tire dynamics simulation model file is generated for the first time, the dynamics simulation model file generation method of the tire system includes:

[0055] Step S1, defining row variables based on the description of variable parameters in the front tire dynamics simulation modeling template, and establishing a first array consisting of the row number of the row where the variable parameters are located in the front tire dynamics simulation modeling template and the corresponding row variables;

[0056] Step S2, defining row variables based on the description of the variable parameters in the rear tire dynamics simulation modeling template, and establishing a second array consisting of the row number of the row where the variable parameters are located in the rear tire dynamics simulation modeling template and the corresponding row variables;

[0057] Step S3, assigning values ​​to row variables in a target array, the target array including a first array and / or a second array; the row variables in the first array are descriptions of variable parameters in a front tire dynamics simulation modeling template, and the row variables in the second array are descriptions of variable parameters in a rear tire dynamics simulation modeling template;

[0058] Step S4, obtaining a tire modeling type value input by a user;

[0059] Step S5, if the tire modeling type value is the first type value, then write each row variable in the first array and the row data of each fixed parameter in the front tire dynamics simulation modeling template into a preset first new file in order of row numbers;

[0060] Step S6, if the tire modeling type value is the second type value, then write each row variable in the second array and the row data of each fixed parameter in the rear tire dynamics simulation modeling template into a preset second new file in order of row numbers;

[0061] Step S7, if the tire modeling type value is the third type value, each row variable in the first array and the row data of each fixed parameter in the front tire dynamics simulation modeling template are written into the first new file in the order of row numbers, and each row variable in the second array and the row data of each fixed parameter in the rear tire dynamics simulation modeling template are written into the second new file in the order of row numbers.

[0062] It is understandable that after the first array and the second array are established for the first time, only steps S3 to S7 need to be performed when modeling again in the subsequent step. Figure 1 shown.

[0063] In this embodiment, the variable parameters in the front tire dynamics simulation modeling template may include any one or more of the front tire dynamics simulation modeling template name, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body property file, and contact type. The following is an example of the variable parameters in the front tire dynamics simulation modeling template including the front tire dynamics simulation modeling template name, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body property file, and contact type. The fixed parameters in the front tire dynamics simulation modeling template are parameters other than variable parameters. The names of the row variables corresponding to the eight variable parameters of the front tire defined in step S1 are Line_TEMPLATE_NAME1, Line_MINOR_ROLE1, Line_MASS1, Line_IXX1, Line_IYY1, Line_IZZ1, Line_PROPERTY_FILE1, and Line_CONTACT_TYPE1. After assigning a value to each row variable in step S3, "Line_TEMPLATE_NAME1 == TEMPLATE_NAME = full_pathname + tire_filename" can be obtained. tire_filename is the full path + file name), "Line_MINOR_ROLE1==MINOR_ROLE='front'", "Line_MASS1==MASS=20", "Line_IXX1==IXX=50000", "Line_IYY1==IYY= 50000", "Line_IZZ1==IZZ=10000", "Line_PROPERTY_FILE1==PROPERTY_FILE='xxx.tir'", "Line_CONTACT_TYPE1==CONTACT_TYPE='handling'".

[0064] In this embodiment, the variable parameters in the rear tire dynamics simulation modeling template may include any one or more of the rear tire dynamics simulation modeling template name, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body property file, and contact type. The following is an example of the variable parameters in the rear tire dynamics simulation modeling template including the rear tire dynamics simulation modeling template name, tire role, tire mass, X moment of inertia, Y moment of inertia, Z moment of inertia, tire flexible body property file, and contact type. The fixed parameters in the rear tire dynamics simulation modeling template are parameters other than the variable parameters. The names of the row variables corresponding to the eight variable parameters of the rear tire defined in step S2 are Line_TEMPLATE_NAME2, Line_MINOR_ROLE2, Line_MASS2, Line_IXX2, Line_IYY2, Line_IZZ2, Line_PROPERTY_FILE2, and Line_CONTACT_TYPE2, respectively. After assigning a value to each row variable in step S3, "Line_TEMPLATE_NAME2 == TEMPLATE_NAME = full_pathname + tire_filename" full(l_pathname + tire_filename is the full path + file name), "Line_MINOR_ROLE2==MINOR_ROLE='front'", "Line_MASS2==MASS=20", "Line_IXX2==IXX=50000", "Line_IYY2==IYY= 50000", "Line_IZZ2==IZZ=20000", "Line_PROPERTY_FILE2==PROPERTY_FILE='xxx.tir'", "Line_CONTACT_TYPE2==CONTACT_TYPE='handling'".

[0065] The first array constructed in step S1 is:

[0066] Arr_front_tire==[(8,Line_TEMPLATE_NAME1),

[0067] (10,Line_MINOR_ROLE1),

[0068] (23,Line_MASS1),

[0069] (25,Line_IXX1),

[0070] (26,Line_IYY1),

[0071] (27,Line_IZZ1),

[0072] (31,Line_PROPERTY_FILE1),

[0073] (32,Line_CONTACT_TYPE1)]

[0074] The second array is:

[0075] Arr_rear_tire==[(8,Line_TEMPLATE_NAME2),

[0076] (10,Line_MINOR_ROLE2),

[0077] (23,Line_MASS2),

[0078] (25,Line_IXX2),

[0079] (26,Line_IYY2),

[0080] (27,Line_IZZ2),

[0081] (31,Line_PROPERTY_FILE2),

[0082] (32,Line_CONTACT_TYPE2)]

[0083] Of course, if only the front tire dynamics simulation model file needs to be generated, the target array in step S3 is the first array; if only the rear tire dynamics simulation model file needs to be generated, the target array in step S3 is the second array; if both the front tire dynamics simulation model file and the rear tire dynamics simulation model file need to be generated at the same time, the target array in step S3 includes the first array and the second array.

[0084] In step S5, the tire modeling type value tiretype is a first type value, indicating that the user only needs to establish a front tire dynamics simulation model; in step S6, the tire modeling type value tiretype is a second type value, indicating that the user only needs to establish a rear tire dynamics simulation model; in step S7, the tire modeling type value tiretype is a third type value, indicating that the user needs to establish both a front tire dynamics simulation model and a rear tire dynamics simulation model. The values ​​of the first type value, the second type value, and the third type value can be 1, 2, and 3, respectively.

[0085] In steps S5 and S7, each row variable in the first array and the row data of each fixed parameter in the front tire dynamics simulation modeling template are written into a preset first new file in order of row numbers, which may include: starting from the current row number being the first preset value, looping through the first preset process until the current row number is the second preset value; the first preset process includes: obtaining the current row number; if the current row number exists in the first array, writing the row variables corresponding to the current row number in the first array into the first new file in order; if the current row number does not exist in the first array, writing the row data corresponding to the current row number in the front tire dynamics simulation modeling template into the first new file; adding one to the current row number.

[0086] In steps S6 and S7, each row variable in the second array and the row data of each fixed parameter in the rear tire dynamics simulation modeling template are written into the preset second new file in the order of row numbers, which may include: starting from the current row number being the third preset value, looping the second preset process until the current row number is the fourth preset value; the second preset process includes: obtaining the current row number; if the current row number exists in the second array, writing the row variable corresponding to the current row number in the second array into the second new file; if the current row number does not exist in the second array, writing the row data corresponding to the current row number in the rear tire dynamics simulation modeling template into the second new file; adding one to the current row number.

[0087] The front tire dynamics simulation modeling template and the rear tire dynamics simulation modeling template of this embodiment both have 37 lines, so the first preset value and the third preset value can be 1, and the second preset value and the fourth preset value can be 37. The principle of steps S5-S7 is as follows Figure 2 As shown in 3, Figure 2 The first array Arr_front_tire[] and Figure 3 The second elements in the second array Arr_rear_tire[] should all be row variables. The number "1" is used in the figure to simply replace the English name of the row variable.

[0088] Taking the generation of the front tire dynamics simulation model file as an example, first, the current row number is 1, and row number 1 is not in the first array Arr_front_tire[]. Then the row data of the first row in the front tire dynamics simulation modeling template is written into the first new file file_front_tire_mdl. In this embodiment, writing the row data corresponding to the current row number in the front tire dynamics simulation modeling template into the first new file can include: storing the front tire dynamics simulation modeling template as a behavior string into the Numpy list class variable val_list_front_tire, the statement expression is file_front_tire_tpl = open(full_path+front_tire_filenametpl) (file_front_tire_tpl is the name of the front tire dynamics simulation modeling template, full_path+front_tire_filenametpl are the full path + file name opened respectively), val_list_front_tire = file_front_tire_tpl.readlines(); writing the row data corresponding to the current row number in the list class variable val_list_front_tire into the first new file file_front_tire_mdl. Writing the row data corresponding to the current row number in the rear tire dynamics simulation modeling template into the second new file may include: storing the rear tire dynamics simulation modeling template as a behavior string into the Numpy list class variable val_list_rear_tire; writing the row data corresponding to the current row number in the list class variable val_list_rear_tire into the second new file file_rear_tire_mdl.

[0089] For the first row, write the first row of data in val_list_front_tire to the first row of the first new file file_front_tire_mdl. Then add one to the current row number, the current row number is 2, and row number 2 is also not in the first array Arr_front_tire[]. Write the second row of data in val_list_front_tire to the second row of the first new file file_front_tire_mdl. Row numbers 3 to 7 are not in the first array Arr_front_tire[]. Write the third to seventh rows of data in val_list_front_tire in sequence to the third to seventh rows of the first new file file_front_tire_mdl. Row number 8 exists in the first array Arr_front_tire[]. Write the row variable Line_TEMPLATE_NAME1 corresponding to row number 8 in the first array Arr_front_tire[] to the eighth row of the first new file file_front_tire_mdl. This process is repeated until the 37th line of data in val_list_front_tire is written into the 37th line of the first new file file_front_tire_mdl. The first new file file_front_tire_mdl.sub is the required front tire dynamics simulation model file. When the file_front_tire_mdl.sub is opened in the Adams software, the following can be obtained: Figure 4 The front tire dynamics simulation model is shown. The process of generating the rear tire dynamics simulation model file is the same as that of generating the front tire dynamics simulation model file, which will not be repeated here.

[0090] As can be seen from the above, this embodiment assigns values ​​to row variables in the target array, and the target array includes the first array and / or the second array, so that the maintenance of variable parameters can be realized; according to the tire modeling type value input by the user, the front tire dynamics simulation model file and / or the rear tire dynamics simulation model file can be automatically selected to be generated. In the process of generating the tire dynamics simulation model file, only the tire modeling type value needs to be input and a small number of variable parameters need to be maintained, which improves the efficiency of generating the tire dynamics simulation model file.

[0091] like Figure 5 As shown, this embodiment also provides a device for generating a dynamics simulation model file of a tire system, comprising:

[0092] An assignment module is used to assign values ​​to row variables in a target array, the target array includes a first array and / or a second array; the row variables in the first array are descriptions of variable parameters in the front tire dynamics simulation modeling template, and the row variables in the second array are descriptions of variable parameters in the rear tire dynamics simulation modeling template;

[0095] The writing module is further used to write each row variable in the second array and the row data of each fixed parameter in the rear tire dynamics simulation modeling template into a preset second new file in the order of row numbers if the tire modeling type value is a second type value;

[0096] The writing module is also used to write each row variable in the first array and the row data of each fixed parameter in the front tire dynamics simulation modeling template into the first new file in the order of row numbers if the tire modeling type value is the third type value, and write each row variable in the second array and the row data of each fixed parameter in the rear tire dynamics simulation modeling template into the second new file in the order of row numbers.

[0101] The array module is also used to establish a second array consisting of the row number of the row where the variable parameter is located in the rear tire dynamics simulation modeling template and the corresponding row variable.
