National Standard of the People's Republic of China GB/T 36457—2018

Modeling Method for Virtual Prototype of Complex Products

Standard Overview

This standard proposes a systematic modeling method to solve the multi-disciplinary, multi-level and multi-organization collaborative modeling and simulation problems in the development of complex products. Its core is to adopt a port-based modeling strategy to encapsulate heterogeneous simulation models into standardized components to achieve rapid construction and efficient collaboration.

Standard System Framework

Composition of high-level models of virtual prototypes

High-level modeling process and construction criteria of virtual prototype

Modeling process:

1. Based on the principle of functional independence, hierarchical division of product object system is carried out.
2. Structural modeling is carried out according to system information description.
3. Behavioral modeling is carried out for the component models of the system.

Construction guidelines:

1. Simulation components provide standard interfaces for information exchange.
2. The association between simulation components is established through the connection between matching ports.
3. High-level models need to describe the scenarios of event interaction between simulation components.

Implementation recommendations

In order to effectively implement this standard, it is recommended to:

• Adopt a hierarchical modeling strategy to ensure the separation of abstract levels of different models.
• During the system development process, give priority to the use of standardized simulation components.
• Establish a complete metamodel framework (M2F) to support multidisciplinary collaborative simulation.
