The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0063] The modeling method, device, electronic device and storage medium of the engine cylinder head of the embodiment of the present application are described below with reference to the accompanying drawings. In view of the problem of long development cycle of the engine cylinder head in the related art mentioned in the above background technology, the present application provides a modeling method of the engine cylinder head, in which the modeling model of the cylinder head skeleton of the cylinder head to be modeled is determined according to the combustion system model and the valve mechanism model by obtaining the pre-input combustion system model, the valve mechanism model and the modeling boundary, and the modeling model of the single-cylinder water jacket, the single-cylinder oil cavity and the single-cylinder outer mold is determined according to the modeling model of the cylinder head skeleton, the combustion system model, the valve mechanism model and the modeling boundary, and the modeling models of multiple groups of water jackets, multiple groups of oil cavities and multiple groups of outer molds are copied, and the modeling models of the left and right water jackets and the left and right oil cavities are assembled, and the left cylinder head blank is obtained by using the left modeling model, and the right cylinder head blank is obtained by using the right modeling model, and the cylinder heads on both sides are machined to obtain the cylinder head modeling model. As a result, the problem of long engine cylinder head development cycle in related technologies is solved. Through modular and assembly modeling methods, the design of cylinder heads with complex structures is accelerated and the design cycle of V-type engine cylinder heads is shortened.
[0064] Specifically, Figure 1 A schematic flow chart of a method for modeling an engine cylinder head provided in an embodiment of the present application.
[0065] like Figure 1 As shown, the modeling method of the engine cylinder head includes the following steps:
[0066] In step S201, a combustion system model, a valve train model and a modeling boundary that are input in advance are obtained.
[0067] Specifically, Figure 3 As shown, the embodiment of the present application can pre-acquire the input combustion system model, valve mechanism model and modeling boundary, so as to design an engine cylinder head model that meets the modeling requirements according to the combustion system model, valve mechanism model and modeling boundary.
[0068] In step S202, a modeling model of a cylinder head skeleton of a cylinder head to be modeled is determined according to a combustion system model and a valve train model.
[0069] Specifically, Figure 4As shown, the embodiment of the present application can design the cylinder head skeleton according to the input performance combustion system model and valve mechanism model, and establish a modeling model of the cylinder head skeleton according to the design of the cylinder head skeleton.
[0070] In step S203, the modeling model of the single-cylinder water jacket of the cylinder head to be modeled is determined according to the modeling model of the cylinder head skeleton, the modeling model of the single-cylinder water jacket is copied to obtain multiple groups of water jacket modeling models, and the multiple groups of water jacket modeling models are assembled to obtain the modeling model of the left water jacket and the modeling model of the right water jacket.
[0071] Specifically, Figure 5 As shown, after the design of the cylinder head skeleton is completed, the embodiment of the present application can determine the design of the single-cylinder water jacket according to the modeling model of the cylinder head skeleton, and establish a modeling model of the single-cylinder water jacket. Through the assembly operation of the Cero software, the single cylinder is copied into a multi-cylinder water jacket. For example, a 4-cylinder engine is copied into a 4-cylinder water jacket. Figure 6 As shown, at the connection between the cylinders, through refinement and optimization, a smooth transition is ensured to complete the main structure of the water jacket. The remaining interface sizes of the water jacket, such as the exhaust channel and the water inlet and outlet positions, can also be determined through the whole machine cooling concept. Multiple groups of water jacket modeling models are assembled to obtain the left water jacket modeling model and the right water jacket modeling model.
[0072] In step S204, the modeling model of the single-cylinder oil chamber of the cylinder head to be modeled is determined according to the valve mechanism model, the modeling model of the single-cylinder oil chamber is copied to obtain the modeling model of the multi-cylinder oil chamber, and the modeling model of the multi-cylinder oil chamber is assembled to obtain the modeling model of the left oil chamber and the modeling model of the right oil chamber.
[0073] Specifically, Figure 7 As shown, with the further input of the valve train model, the embodiment of the present application completes the design of the cylinder head oil chamber. The specific steps are similar to the design of the single-cylinder water jacket in step S203. The single-cylinder oil chamber is designed first, and then the array is copied into 4-cylinder oil chambers through assembly operations, and the connections are refined to obtain 4-cylinder oil chambers, such as Figure 8 As shown, the modeling models of the multi-cylinder oil chambers are assembled to obtain the modeling model of the left oil chamber and the modeling model of the right oil chamber.
[0074] In step S205, the modeling model of the single-cylinder outer mold is determined based on the modeling boundary, and the modeling model of the single-cylinder outer mold is copied to obtain the modeling models of multiple groups of outer molds, and the modeling models of the multiple groups of outer molds are assembled to obtain the modeling models of the left outer mold and the modeling models of the right outer mold.
[0075] Specifically, Fig. 9As shown, the embodiment of the present application completes the design of the single-cylinder outer mold of the cylinder head according to the boundary input of the intake and exhaust sides. The specific steps are similar to the single-cylinder water jacket design in step S203. The single-cylinder outer mold (intake and exhaust direction) is first completed, and then the array is copied into the intake and exhaust directions of the multi-cylinder outer mold through assembly operations, such as Fig.10 As shown, it should be noted that the front and rear end direction structures of the cylinder head outer mold need to be designed separately according to the boundaries, and finally the cylinder head outer mold design is completed, and then the modeling models of multiple groups of outer molds are assembled to obtain the modeling model of the left outer mold and the modeling model of the right outer mold.
[0076] In step S206, the modeling model of the left water jacket, the modeling model of the left oil chamber, the modeling model of the left outer mold, the combustion system model and the valve mechanism model are assembled to obtain the left cylinder head blank, and the modeling model of the right water jacket, the modeling model of the right oil chamber, the modeling model of the right outer mold, the combustion system model and the valve mechanism model are assembled to obtain the right cylinder head blank, and the left cylinder head blank and the right cylinder head blank are machined to obtain the cylinder head modeling models.
[0077] It is understandable that if Fig.11 As shown, the embodiment of the present application can combine the above-mentioned completed modeling model of the left water jacket, the modeling model of the left oil chamber and the modeling model of the left outer mold, together with the combustion chamber, intake duct and exhaust duct of the performance input, to form a left cylinder head blank; similarly, since the single-cylinder water jacket, oil chamber and outer mold have been completed, the same work is repeated to obtain the right cylinder head blank, and finally through machining, the left and right cylinder head blanks are transformed into left and right cylinder head finished products, completing the initial modeling of the cylinder head.
[0078] It should be noted that after obtaining the cylinder head modeling model, the embodiment of the present application can optimize the design of the cylinder head based on relevant CFD / CAE calculations to ensure that the design of the cylinder head can meet the relevant requirements of the whole machine and finally complete the final modeling design of the cylinder head.
[0079] Therefore, if Fig.12 As shown, through the modeling method of the engine steel cover of the embodiment of the present application, compared with the conventional V-type engine cylinder head modeling, the modeling cycle of the entire V-type engine cylinder head can be shortened by 3 months. Through the modular and assembly modeling design of the single-cylinder structure, the entire cylinder head modeling process can be simplified. At the same time, the modeling variables are reduced and the defects of model establishment can be avoided, thereby saving modeling time and meeting the modeling quality requirements.
[0080] Optionally, in some embodiments, after machining the left cylinder head blank and the right cylinder head blank to obtain the cylinder head modeling model, it also includes: generating a reminder instruction of the completion of the cylinder head modeling model; and providing a modeling completion reminder according to the reminder instruction.
[0081] Specifically, in order to enable relevant technical personnel in the field to obtain timely feedback on the modeling cycle, the embodiment of the present application can generate a reminder instruction of the completion of the cylinder head modeling model after machining the left cylinder head blank and the right cylinder head blank to obtain the cylinder head modeling model, and give a reminder according to the reminder instruction.
[0082] In the actual execution process, there are many ways to remind according to the reminder instruction, for example, by controlling the LED light to flash to remind that the modeling is completed, or controlling the buzzer to emit a "beep beep" reminder sound to remind that the modeling is completed, and no specific limitations are made here.
[0083] Optionally, in some embodiments, after assembling the modeling models of multiple groups of water jackets to obtain the modeling model of the left water jacket and the modeling model of the right water jacket, it also includes: determining whether a first modification instruction of the modeling model of the water jacket is received; confirming the first modification structure according to the first modification instruction, and modifying the modeling model of the single-cylinder water jacket according to the first modification structure, using the modeling model of the single-cylinder water jacket to update the modeling models of multiple groups of water jackets, and using the modeling models of multiple groups of water jackets to update the modeling model of the left water jacket and the modeling model of the right water jacket to obtain a new modeling model of the left water jacket and a new modeling model of the right water jacket.
[0084] Specifically, the embodiment of the present application can effectively shorten the modeling cycle through modular and assembly design. For example, when relevant technical personnel need to modify the single-cylinder water jacket model, a first modification instruction can be issued. The embodiment of the present application modifies the modeling model of the single-cylinder water jacket according to the first modification instruction, and the modeling models of multiple groups of water jackets can be synchronously updated according to the modeling model of the single-cylinder water jacket. Furthermore, the modeling models of the left water jacket and the right water jacket can also be synchronously updated according to the modeling model of the single-cylinder water jacket and automatically form a new modeling model of the left water jacket and a new modeling model of the right water jacket.
[0085] In the actual implementation process, the embodiment of the present application can update the modeling models of all water jackets by modifying the modeling model of a single-cylinder water jacket, thereby saving correction time and shortening the development cycle.
[0086] Optionally, in some embodiments, after assembling the modeling models of multiple cylinder oil chambers to obtain the modeling model of the left oil chamber and the modeling model of the right oil chamber, it also includes: determining whether a second modification instruction of the modeling model of the oil chamber is received; confirming the second modification structure according to the second modification instruction, and modifying the modeling model of the single-cylinder oil chamber according to the second modification structure, using the modeling model of the single-cylinder oil chamber to update the modeling models of multiple groups of oil chambers, and using the modeling models of multiple groups of oil chambers to update the modeling models of the left oil chamber and the modeling models of the right oil chamber to obtain a new modeling model of the left oil chamber and a new modeling model of the right oil chamber.
[0087] Similarly, the embodiments of the present application can effectively shorten the modeling cycle through modular and assembly design. For example, when relevant technical personnel need to modify the single-cylinder oil chamber model, a first modification instruction can be issued. The embodiments of the present application modify the modeling model of the single-cylinder oil chamber according to the first modification instruction, and the modeling models of multiple groups of oil chambers can be synchronously updated according to the modeling model of the single-cylinder oil chamber. Furthermore, the modeling models of the left oil chamber and the right oil chamber can also be synchronously updated according to the modeling model of the single-cylinder oil chamber and automatically form a new modeling model of the left oil chamber and a new modeling model of the right oil chamber.
[0088] In the actual implementation process, the embodiment of the present application can update the modeling models of all oil chambers by modifying the modeling model of a single-cylinder oil chamber, thereby saving correction time and shortening the development cycle.
[0089] Optionally, in some embodiments, after assembling the modeling models of multiple groups of external molds to obtain the modeling model of the left external mold and the modeling model of the right external mold, it also includes: determining whether a third modification instruction of the modeling model of the external mold is received; confirming the third modification structure according to the third modification instruction, and modifying the modeling model of the single-cylinder external mold according to the third modification structure, using the modeling model of the single-cylinder external mold to update the modeling models of multiple groups of external molds, and using the modeling models of multiple groups of external molds to update the modeling model of the left external mold and the modeling model of the right external mold to obtain a new modeling model of the left external mold and a new modeling model of the right external mold.
[0090] Similarly, the embodiments of the present application can effectively shorten the modeling cycle through modular and assembly design. For example, when relevant technical personnel need to modify the single-cylinder external mold model, a first modification instruction can be issued. The embodiments of the present application modify the modeling model of the single-cylinder external mold according to the first modification instruction, and the modeling models of multiple groups of external molds can be synchronously updated according to the modeling model of the single-cylinder external mold. Furthermore, the modeling models of the left external mold and the right external mold can also be synchronously updated according to the modeling model of the single-cylinder external mold and automatically form a new modeling model of the left external mold and a new modeling model of the right external mold.
[0091] In the actual implementation process, the embodiment of the present application can update the modeling models of all external molds by modifying the modeling model of a single-cylinder external mold, saving correction time and shortening the development cycle.
[0092] In summary, the embodiment of the present application provides a modeling method for an engine cylinder head. In view of the fact that most structures of the cylinder heads of V-type engines are similar, a certain cylinder of the cylinder head is modeled and designed in a modular way, and then the cylinders are arranged and combined into the final left and right water jackets, oil chambers, and outer molds using an assembly modeling method. Then, the final cylinder head blank is formed through the input combustion system, and then the left and right cylinder head finished products are finally formed according to a similar machining process. Due to the change in the modeling method, the single-cylinder structure can be modified through modeling software such as Cero or CATIA, so that the left and right cylinder heads can be synchronously updated to the latest status, thereby saving modeling time.
