[0039] In the field of rail vehicles, the current technological innovation, R&D and design are still at the stage of simply using the most basic modeling commands of the NX system to draw component models one by one. The products have not achieved modular and parametric design and cannot be flexibly adjusted according to customer needs in a timely manner. During the application process, a large amount of R&D time is spent on simple drawing work, resulting in a long R&D cycle.

[0041] Although the existing technical innovation R&D design solutions can realize the innovative model drawing of product solutions to a certain extent, they have the following disadvantages when put into use:

[0042] Faced with diverse and changing customer demands, flexible adjustments cannot be made in a timely manner.

[0043] The R&D cycle is long and the R&D cost is high.

[0044] The professional requirements for designers are high, but in actual business, it is inevitable to encounter designers with uneven professional abilities, which will lead to the inability to guarantee the design quality and timeliness of design business.

[0045] To solve the above problems, the present invention provides an efficient rail transit product design system and method based on NX technology, which accordingly forms a way to quickly design product solutions. The system combines and derives previous design solutions through the existing functions of NX software and is finally built. The system can improve design efficiency, make the modeling process more efficient and repeatable, and can adapt to different needs and changes.

[0046] Next, the structural components, connection modes and functional principles of the system of the embodiment of the present invention are described in detail based on the drawings. Although the logical order of each operation is shown in the process of describing the operating principle of the system structure, in some cases, the operations shown or described can be performed in a different order than here.

[0047] Embodiment 1

[0048] Figure 1 The schematic diagram of the structure of the efficient rail transit product design system based on NX technology provided by the first embodiment of the present invention is shown. Figure 1 It can be seen that the system includes:

[0049] A component model rule formulation module is configured to analyze the types of product component objects and identify them based on various products with design requirements, and determine matching model building rules respectively;

[0050] A model building module configured to comprehensively build a three-dimensional model of each component based on the NX system according to the model building rules;

[0051] The model combination module is configured to use the PTS product template studio to set up a comprehensive setting dialog box to batch retrieve the three-dimensional models of required parts to combine and obtain the overall model of the target product component;

[0052] The product design scheme conversion module is configured to use the assembly cloning function to clone the product model of the NX platform, and then control the cloned models of each module through the template browser to convert them into a design scheme that matches the product to be analyzed.

[0053] The efficient rail transit product design system based on NX technology provided by the embodiment of the present invention is built by combining and deriving previous design solutions through the existing functions of NX software. The system can improve design efficiency, make the modeling process more efficient and repeatable, and can adapt to different needs and changes.

[0054] In an optional embodiment, the component model rule formulation module includes a component type determination unit, which is configured as follows:

[0055] Based on the products with design requirements, after analyzing and determining the parts to be designed of the products, all the parts to be designed are divided into multiple types, including enterprise standard parts, standard parts and deformable parts.

[0056] The component model rule formulation module includes a model rule adaptability determination unit, which is configured as follows:

[0057] For enterprise standard parts and standard parts, the first model building rule is set to form the three-dimensional models of enterprise standard parts and standard parts based on NX software;

[0058] For the deformable part, deformation parameters are selected according to the functional attributes and process association of the deformable part, and the second model building rules are adopted in combination with the deformation parameters to form a three-dimensional model of the component based on NX software.

[0059] In order to better understand the technical solution of the present invention, the functional structural features of the efficient rail transit product design system based on NX technology in the embodiment of the present invention are described in detail below, taking the construction of the parametric system of the urban rail electric wiper as an example. However, it should be emphasized that the scope of the present invention is not limited by the embodiments, and the scope of the present invention is set forth in the claims; the detailed description of the system features of this implementation case is only an example and cannot be understood as a limitation on the patent of the present invention.

[0060] Firstly, the component type is used to determine the unit analysis. The product to be designed, the urban rail electric wiper, consists of eight modules: drive assembly, wiper blade assembly, wiper arm assembly, through-wall joint, washing system assembly, control box, control switch and connecting wire. Specifically, the analysis shows that the components to be designed of the urban rail electric wiper drive assembly module include: transmission shaft, main swing plate, auxiliary small shaft with hole, small shaft with hole, auxiliary swing plate, through-wall bushing, rotating plate, wiper motor, mounting bracket, nameplate, centering sensor, connecting pipe and auxiliary connecting rod.

[0061] Furthermore, the component type determination unit classifies the components of the urban rail electric wiper drive assembly module and determines the type of each component. Based on this, among the components to be designed of the urban rail electric wiper drive assembly module, the auxiliary small shaft with holes, the small shaft with holes, the auxiliary swing plate, the mounting bracket component, the centering sensor component and the auxiliary connecting rod are determined as enterprise standard parts; the transmission shaft, the main swing plate, the through-wall bushing component, the rotating plate, the wiper motor component, the nameplate and the connecting pipe are deformable parts.

[0062] Determining an applicable model building rule (scheme) according to the type of the component to be designed by using the model rule adaptability determination unit, so as to build a component model based on the NX system;

[0063] Specifically, in an optional embodiment, for the enterprise standard parts of the urban rail electric wiper drive assembly module, including the auxiliary small shaft with a hole, the small shaft with a hole, the auxiliary swing plate, the mounting bracket component, the centering sensor component and the auxiliary connecting rod enterprise standard parts, the model rule adaptability determination unit is set to adopt the first model building rule to build the corresponding component three-dimensional model based on the NX system according to the functional attributes of the component;

[0064] For the deformable parts of the urban rail electric wiper drive assembly module, the drive shaft, the main swing plate, the through-wall bushing, the rotating plate, the wiper motor, the nameplate and the connecting pipe are deformable parts; the model rule adaptability determination unit selects deformation parameters according to the functional attributes and process associations of the deformable parts, and determines to adopt the second model construction rule (scheme) in combination with the deformation parameters of each component to be designed, so as to form a three-dimensional model of the component based on the NX system; the second model construction rule is a parametric modeling strategy.

[0065] For example, for the deformable part transmission shaft, the model rule adaptability determination unit selects its axis length parameter as the deformation parameter according to its functional attributes and process associations, and adopts the second model construction rule parametric modeling strategy in combination with the axis length parameter; for the deformable part through-wall sleeve component, the model rule adaptability determination unit selects the associated transmission shaft length parameter as the deformation parameter according to its functional attributes and process associations, and sets the second model construction rule parametric modeling strategy in combination with the transmission shaft length; for the deformable part rotating plate, the model rule adaptability determination unit selects the associated hole spacing parameter as the deformation parameter according to its functional attributes and process associations, and sets the second model construction rule parametric modeling strategy in combination with the hole spacing parameter.

[0066] The classification and modeling rules of the self-made parts to be designed for the urban rail electric wiper drive assembly module are shown in Table 1.

[0067] Table 1 Classification and modeling rules list of key self-made parts of drive assembly module

[0068]

[0069]

[0070] Furthermore, the model building module comprehensively builds the three-dimensional model of each component based on the NX system according to the model building rules;

[0071] The model building module creates a model parameter setting frame for controlling parameter configuration and selection changes of each component, and forms component models corresponding to different selections and parameters based on the model parameter setting frame according to the matching model building rules.

[0072] In a preferred embodiment, the model building module flexibly sets the model information and parameter values ​​of the current components through the corresponding model parameter setting box based on the NX system, so as to facilitate technical personnel to interactively intervene according to needs and comprehensively establish three-dimensional models corresponding to different models of components and different parameter values ​​of the same model for each component.

[0073] In actual application, for example, for a deformable transmission shaft, the model building module considers its deformation parameters and shaft length parameters to make a model parameter setting frame, controls the transmission shaft model information and parameter value changes, and uses the second model building rule to perform parametric modeling to comprehensively establish a three-dimensional model corresponding to different parameter values ​​and models of the transmission shaft;

[0074] For the through-wall sleeve component of the deformable part, the model building module considers its deformation parameter transmission shaft length to make a model parameter setting frame, controls the model information and parameter value changes of the through-wall sleeve component, and uses the second model building rule to perform parametric modeling to comprehensively establish a three-dimensional model corresponding to different parameter values ​​and model information of the through-wall sleeve component;

[0075] For the deformable rotating plate, the model building module considers its deformation parameters and hole spacing parameters to make a model parameter setting frame, controls the model information and parameter value changes of the rotating plate, and uses the second model building rule based on NX software to perform parametric modeling to comprehensively form a three-dimensional model with different parameter values ​​and model information of the rotating plate. Figure 2 An example diagram of the modeling effect of parametric modeling of a rotating plate based on NX software is shown, wherein the hole spacing parameter L_Z is the deformation parameter (variable parameter) of the rotating plate component of the deformable part; the parametric models of the remaining deformable parts can be adaptively created by referring to this method.

[0076] After the corresponding 3D models of all parts that meet the design requirements of the product to be designed are established, the model combination module uses the PTS product template studio to set up a comprehensive setting dialog box to batch retrieve the 3D models of the required parts to combine and obtain the overall model of the target product assembly.

[0077] Specifically, in an optional embodiment, a PTS product template studio is used to create a comprehensive setting dialog box to control the parameters or selection changes of each component, based on which the assembly constraints matching the target product components are combined and assembled to obtain the overall model of the target product components; wherein the model information and parameter values ​​of the component models to be retrieved are flexibly set through the comprehensive setting dialog box, so that the target product components (such as the drive assembly module of an urban rail electric wiper) can be changed into different design combination schemes.

[0078] In actual application, for example, for the drive assembly module of urban rail electric wipers, the PTS product template studio is used to create a comprehensive setting dialog box to control the parameters or selection changes of each component under the drive assembly module. Based on the set parameters or selection, the constructed component model is called, and combined with the assembly constraints matching the drive assembly module to obtain the overall model of the current drive assembly module. Figure 3 An example diagram of an interface for combining an overall model of a driving assembly module based on a coordinated setting dialog box according to an embodiment of the present invention is shown.

[0079] Repeat the above operations to create model combinations of the eight modules of the urban rail electric wiper, so as to facilitate further assembly into the model design result of the entire urban rail electric wiper product; based on the NX system, the PTS product template studio that associates all modules at the top level of the product to be designed can realize product solution changes. Figure 4 An example diagram of an interface for combining an overall product model of an urban rail electric wiper product according to an embodiment of the present invention based on a coordinated setting dialog box is shown.

[0080] The product design scheme conversion module is configured to use the assembly cloning function to clone the product model of the NX platform, and then control the cloned models of each module through the template browser to convert them into a design scheme that matches the product to be analyzed. Figure 5 The following is an example diagram of an interface for converting a product design scheme of an urban rail electric wiper product according to an embodiment of the present invention into a product design scheme through a template browser.

[0081] The efficient rail transit product design system based on NX technology provided by the embodiment of the present invention is applied, and the existing functions of NX software are used to build a parametric design system, so that different products can be designed by selecting models through dialog boxes or inputting parameters. Compared with the existing design methods, it has at least the following advantages:

[0082] 1. Through simple parameter input and selection for scheme design, the modeling process is faster, more efficient, repeatable, easy to expand, and can adapt to different needs and changes.

[0083] 2. The design efficiency is significantly improved, and the labor cost of the project is reduced. Taking the design of urban rail electric wiper products using the system of the present invention as an example, the design cycle of the product solution design is shortened from the original 3 days to 1 day.

[0084] 3. The basic data for building the system are existing mature products, and the reliability of component structure models is guaranteed, which can effectively reduce design quality problems caused by insufficient capabilities of designers and improve product design quality.

[0085] In the efficient rail transit product design system based on NX technology provided by the embodiment of the present invention, each module or unit structure can operate independently or in combination according to actual parameter selection requirements and system function application requirements to achieve corresponding technical effects.
