Additionally, the number of shaft segments may also be calculated, including: firstly, calculating the length of the head of the dummy bar, then calculating the length of the bar body, then calculating the number of the sections of the bar body and rounding, and finally calculating the length of the tail section to obtain the total number of the sections of the dummy bar; the height position of the pin shaft in the chain link can be calculated, and 0/5 rounding is realized by using an expression; and the If statement can be used for judging and assigning the target parameters, so that the parameter association of different part sizes in different specifications is realized. As shown in fig. 4, the target parameters may further include relevant parameters such as a pitch angle, a number of dummy bars, a number of pitch, a length of a shaft, and a number of shaft sections, which are determined by the above-mentioned methods such as pitch position optimization, shaft section number calculation, and the like.
In concrete implementation, steps 303 and 304 are a dummy bar body creation process, and since the bars of a plurality of dummy bars in the same project are the same, only one bar body needs to be created in one project, for example, A, B, C, D, E kinds of dummy bars are needed in the project, only a dummy bar body a may be created, and the dummy bar body a is used in assembling A, B, C, D, E dummy bars.
In one embodiment, the plurality of parts of the dummy bar body includes at least: the chain comprises a plurality of chain links, tail sections, pin shafts, shaft check rings and oil cups;
step 304 may include:
assembling a plurality of chain links, tail sections, pin shafts, shaft check rings and oil cups of the dummy bar body;
and adjusting each part parameter of the assembled dummy bar body based on the incidence relation between each part parameter of the dummy bar body and the target parameter of the dummy bar body and the incidence relation between each part parameter of the dummy bar body, and creating the dummy bar body.
In specific implementation, an assembly file for a shaft assembly a may be created to create a dummy shaft a, a material attribute and a display name attribute having a value of "a shaft assembly" may be added, and a flow of the shaft assembly a may include: creating a file → creating a detailed level → assembling parts → associating parameters → a shaft hole groove positioning rule → a shaft collar matching rule, wherein the detailed level can be expressed by a project. When the assembly parts are created, the default detail level is "main", because the assemblies have the suppression conditions of parts, a new detail level needs to be created in all the assemblies, and can be named as a project, then the control operation for the assembly body model is carried out in the project detail level, the expression of the assembly body model is controlled by using different detail levels, and the specific process of creating the A dummy bar body in the steps 303 and 304 is described below.
Firstly, assembling an initial dummy bar body a, obtaining parts such as a plurality of chain links, tail sections, pin shafts, shaft check rings, oil cups and the like of the dummy bar body a in a part library, fig. 6 is an assembly schematic diagram of the dummy bar body in an embodiment of the present invention, and as shown in fig. 6, assembling the parts to obtain the initial dummy bar body a, wherein the assembling step may include: firstly, a first chain link is inserted and fixed by using a default coordinate system, then parts such as a pin shaft, an oil cup and the like are inserted, and then the chain links, the pin shaft and the like are arrayed along the direction of a dummy bar, and at the moment, the number and the interval of the arrays can be temporarily set to any value. Inserting tail section parts by the same method, generating constraint relation by using each reference surface and the first chain link, and temporarily setting any value for the same distance value.
Then, step 303 is performed, and according to the target parameter of the dummy bar body a, the association relationship between each part parameter of the dummy bar body a and the target parameter of the dummy bar body a and the association relationship between each part parameter of the dummy bar body a are determined, which may be determined by equation assignment or other formulas, which is not limited in the present invention.
Then, step 304 is performed, according to the above-mentioned association relationship, parameters of each part of the initial dummy bar body a are adjusted, and a dummy bar body a meeting the actual requirement can be created. When the model parameters or the parameters input by the user are changed, namely the target parameters of the dummy bar body A are changed, a new dummy bar body A can be directly created according to the incidence relation.
In one embodiment, the correlation between the parameters of the parts of the dummy bar in step 303 may include:
the incidence relation between the pin shaft parameters and the positions of the pin shaft holes in the chain links and the positions of the grooves of the shaft check rings and the incidence relation between the pin shaft parameters and the parameters of the shaft check rings.
In specific implementation, parameter association is needed because different shaft widths and different shaft diameters affect the positions of the pin shaft holes and the positions of the grooves of the shaft retainer rings on the chain links. The shaft hole groove positioning rule can comprise that the positioning is carried out by referring to the structural size of the pin shaft so as to drive the corresponding change of the position of the pin shaft hole on the shaft body chain link and the position of the shaft retainer ring groove, and the positioning of the pin shaft parameter in the position of the shaft hole and the position of the shaft retainer ring groove is directly obtained from the pin shaft part and driven by an expression. In addition, because the shaft retainers correspond to different specifications when the diameter of the pin shaft changes, fig. 7 is a schematic diagram of a matching rule of the shaft retainers in the embodiment of the present invention, and as shown in fig. 7, the matching rule of the shaft retainers may include that all the used shaft retainers of all the specifications are inserted into the shaft body assembly and positioned, and then the shaft retainer corresponding to the specification is selected according to the diameter of the pin shaft.
In specific implementation, steps 305 and 306 are a dummy bar head creation process, and since the dummy bar heads of a plurality of dummy bars of the same project are different, in one project, a plurality of dummy bar heads need to be created, for example, A, B, C, D, E kinds of dummy bars are needed in the project, and A, B, C, D, E five dummy bar heads need to be created.
In one embodiment, the plurality of parts of each dummy bar head comprises at least: the chain comprises a plurality of chain links, a head section, a pin shaft, a baffle plate, a retaining ring for the shaft and an oil cup;

Then, in step 305, according to the target parameter of the dummy bar head a, the association relationship between each part parameter of the dummy bar head a and the target parameter of the dummy bar head a and the association relationship between each part parameter of the dummy bar head a are determined, which may be determined by assigning an equation or other formulas, which is not limited in the present invention.
Then, step 304 is performed, and according to the above-mentioned correlation, parameters of each part of the initial a dummy bar head are adjusted, so as to create an a dummy bar head meeting the actual requirement.

Fig. 9 is a schematic diagram of parameter transmission in the embodiment of the present invention, as shown in fig. 9, in fig. 9: "1" may be a parameter association between the same-level parts, for example, the parameter of the a pin may be transmitted to the a link; the '2' can transfer the parameters of the general layout of the dummy bar A to the general assembly of the dummy bar A, belonging to the transfer of the parameters from the sketch model to the general assembly part; the '3' can transfer parameters of the A shaft assembly and the A dummy bar head assembly to the A dummy bar general assembly, and belongs to the transfer of parameters from parts to general assembly parts; the '4' can be used for transmitting the parameters of the overall layout of the A dummy bar to all parts in the A bar body assembly and the A dummy bar head assembly to realize the transmission parameters from the sketch model to the parts; "5" can be the parameter of the total layout of the A dummy bar is transferred to the total layout of the B dummy bar and other dummy bar total layouts, and since part of the parameters of the B-E dummy bar are the same as those of the A dummy bar, such as the nominal length of a chain link, the diameter of a pin shaft, the width of a bar body and the like, the parameters can be transferred from the A dummy bar in the whole.

adjusting the position of the dummy bar body relative to the dummy bar head based on the length of the dummy bar head; wherein, the length of the dummy bar head is the target parameter of the dummy bar.
Since parameters of connecting parts between different dummy bar heads and dummy bars are different, parameter adjustment needs to be performed based on target parameters of the dummy bar, for example, the distance of the dummy bar body relative to the dummy bar head is changed, and the position of the dummy bar body relative to the dummy bar head needs to be adjusted based on the length of the dummy bar head, so as to create an A dummy bar meeting the actual requirement. When the model parameters or the parameters input by the user are changed, namely the target parameters of the dummy bar A are changed, a new dummy bar A can be directly created according to the target parameters of the dummy bar A. The dummy bar is created B, C, D, E in the same way and will not be described in detail here.
