GB/T 36457-2018Modeling method of complex product virtual prototype (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

Due to its complexity, complex product virtual prototypes usually involve many different fields, including mechanical systems, electronics, control, software, etc. Complex products often have complex hierarchical structures and complex behaviors, as well as cooperation between different development organizations and units. In order to be virtual The comprehensive simulation analysis of the prototype is usually required to combine the complex distributed heterogeneous systems in various fields and units into one. Perform co-simulation. The core idea of virtual product modeling and simulation theory for complex products is to use a port-based modeling strategy to create virtual samples. The various heterogeneous simulation models involved in the machine are described as standardized simulation components, and the multi-discipline virtual samples are realized by the combination of simulation component models. The rapid construction of the machine. Models with heterogeneous mechanisms, heterogeneous model types, and heterogeneous modeling methods are encapsulated into standard imitations. True component model; even if it is a black box model developed with various commercial software, it can also be integrated by simulation software. The adapter encapsulates them into a standard simulation component model to achieve the purpose of shielding model heterogeneity.

The virtual product modeling method for complex products proposed in this standard is a model-driven complex system modeling and simulation method. Method, based on the definition of the meta-model framework (M2F), to summarize, integrate or equivalently replace each element, using a more engineered representation To describe the high-level model of the virtual prototype to solve the multi-disciplinary, multi-level and multi-disciplinary development of multi-disciplinary virtual prototypes in today's complex products. Organizational (department) collaborative standardization of modeling and simulation.
