[0046] In order to solve the problem of uncontrolled model technical status, an embodiment of the present invention provides a model technical status control method and system for a launch vehicle. First, a product structure tree of the launch vehicle is created to determine the various design levels of the launch vehicle. Then, an object to be studied is created in the relevant nodes of each level of the product structure tree to improve the relevant architecture of the launch vehicle. The object to be studied is modeled according to its level in the product structure tree to obtain a digital model object corresponding to the object to be studied. Then, a corresponding model baseline version is created for the digital model object to control the technical status of the digital model object and realize the solidification and management of the technical status of the model, thereby effectively improving the collaborative efficiency and design quality and reducing the design cost.
[0047] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0048] An embodiment of the present invention provides a method for controlling the technical status of a launch vehicle model, comprising the following steps:
[0049] Step 101: Create a product structure tree for the launch vehicle.
[0050] Among them, the product structure tree uses a tree structure to represent the tasks in the launch vehicle development process. It is a structured description of the launch vehicle development process and results. The product structure tree has related nodes at different levels. Specifically, the product structure tree is a tree structure, which contains root nodes, intermediate nodes, and leaf nodes at different levels. The intermediate nodes extend from the root node and the number is unlimited, and each intermediate node extends an unlimited number of intermediate nodes or leaf nodes. For the form of the product structure tree, please refer to Figure 2 The root node is the X launch vehicle. The first-level intermediate nodes include requirements management and system FLP (functional, logical, physical) architecture design. The next level of intermediate nodes below requirements management includes user requirements and system requirements. User requirements and system requirements each extend into intermediate nodes or leaf nodes. The next level of intermediate nodes below the system FLP architecture design includes the functional model, logical architecture, and physical architecture, with further extensions. This indicates that the launch vehicle product structure tree can identify each design level of the launch vehicle, providing a foundation for its development.
[0051] Step 102: Create an object to be studied in the relevant nodes of each level, so that the object to be studied and the relevant nodes correspond to each other.
[0052] Specifically, the objects to be studied are objects created according to the needs of relevant nodes, including but not limited to: architecture models, indicator parameters, three-dimensional models, design documents, and research and test documents. Figure 2 Take the user requirements in the example, create relevant documents according to the user requirements, and associate them with the nodes corresponding to the user requirements.
[0053] During the creation process, the corresponding research objects are created based on the level of the relevant nodes. Furthermore, because the upper and lower levels are closely related, the research objects of the relevant nodes of the previous level can be combined with the relevant nodes of the current level to create the research objects of the current level. This can gradually improve the relevant architecture of the launch vehicle, effectively improving collaborative efficiency and reducing the design error rate.
[0054] Furthermore, after creating the object to be studied in the relevant nodes of each level, the object to be studied is coded according to one or more codes among the model code, product design serial number, basic code code, and sequence code. The coding of the object to be studied is used to help standardize management, quick search, and quick identification. For example Figure 3 These are several objects to be studied in the logical architecture. Each object corresponds to a logical step and has a corresponding code. This code is used to quickly find the object to be studied and can be made public in subsequent extreme versions for easy search.
[0055] Step 103 : Modeling is performed according to the level of the object to be studied in the product structure tree to obtain a digital model object corresponding to the object to be studied.
[0056] During the modeling process, the object to be studied is converted into a digital model representation to obtain a digital model object. In practical applications, modeling tools can be used for modeling. For example, SMW modeling tools can be used to model the model according to the model level. The completed model is saved under the corresponding product structure tree node.
[0057] Because each object to be studied is converted into a digital model object, the number of digital model objects for a launch vehicle is enormous. Furthermore, these objects interact in a networked manner. If a single digital model object fails, the quality of the entire launch vehicle will be affected. Therefore, to prevent errors in digital model objects, after obtaining them, the consistency and integrity of the digital model objects are checked. For example, this checks ensure that all functions are supported by the corresponding architecture, that all functions are implemented, and that all function transfers are physically achieved.
[0058] In some optional implementations, digital model objects are also reviewed and approved based on the review level determined by the rocket's actual business operations to strictly control model release. Specifically, different approval processes are defined based on the level of the digital model object, and review and approval are carried out according to this approval process.
[0059] In addition, since the digital model objects are visual, e.g. Figure 4 Therefore, during the review, the digital model object can be converted into a picture, and the review can be performed on the picture. For example, review comments can be generated on the picture to facilitate modification of the digital model object.
[0060] Step 104: Create a corresponding model baseline version for the digital model object.
[0061] Specifically, the technical state of a digital model object is a logical component of the digital model object. It is the hardware, software, or a collection of these components that fulfills the digital model's ultimate functionality and is designated as a single entity for technical state management. The technical state of a digital model object must be maintained in a controlled manner. Therefore, it is necessary to create a corresponding model baseline version for each digital model object. This model baseline version is used to implement technical state control for the digital model object.
[0062] Furthermore, the model baseline version refers to a version fixed at a specific moment in the development process of the technical status of the digital model object. The model baseline version serves as both an activity baseline in the development and production process of the launch vehicle and a determination baseline for changes in the technical status. The model baselines in the model baseline version are divided into: requirement baseline, function baseline and allocation baseline. In the specific implementation process, when the digital model object is approved, the corresponding model baseline version can be created and solidified. For the model baseline version, please refer to Figure 5 shown.
[0063] Because the technical status of a digital model object can be changed, its related parameters can be modified, such as by changing its management records, analysis, or execution process. Furthermore, since the model baseline version can serve as a criterion for determining technical status changes, after a digital model object's technical status is changed, a corresponding model baseline version can be created based on the changed digital model object, ensuring that the digital model object and the model baseline version correspond to each other.
[0064] The above is the implementation process of the model technical status control of the launch vehicle, which can solidify and manage the technical status of the model, thereby effectively improving the collaborative efficiency and design quality and reducing the design cost.
