Embodiment 1

[0059] Step 1. Description of multidisciplinary simulation system requirements

[0060] The requirements description of multidisciplinary simulation system mainly includes three aspects: system composition framework description, model interface parameter description and logical relationship description.

[0061] 1) Composition frame description

[0062] The description of the multidisciplinary simulation system framework should be based on the principle of function independence, and the product object system should be divided. Normally each subject major should be taken as a separate module. When describing the system framework, it is necessary to consider the correspondence with the physical structure of the existing complex system, which is usually represented by a composition framework diagram.

[0063] Such as figure 1 As shown in , the composition framework diagram represents the input and output relationship between each model, and the key physical parameters of each ...

Abstract

The invention discloses a multidisciplinary co-simulation realization method based on a reflective memory network. The method comprises the steps that multidisciplinary simulation system demand description is performed; IOCE model description is performed; an IOCE model is realized; and data management and general control management are performed, wherein the IOCE model contains input, output, calculation and events and is triggered by a certain message to generate an event response under a certain external or internal input condition, calculation is performed according to the response, and a result is output. Through the multidisciplinary co-simulation realization method, the problems that a traditional complex weapon system is long in simulation running consumed time in a digital simulation process, disciplinary models cannot be coupled, and a simulation result is low in confidence are solved, and quasi-real-time high-precision multidisciplinary co-simulation is realized.

Description

technical field [0001] The invention relates to a method for realizing multidisciplinary collaborative simulation. More specifically, it relates to a realization method of multi-disciplinary co-simulation based on reflective memory network. Background technique [0002] A reflective memory network is a special type of shared memory system designed to enable multiple independent computers to share common data sets. Reflective memory networking keeps an independent copy of the entire shared memory in each subsystem. Each subsystem enjoys full and unrestricted access, and can modify local datasets at very high local memory write speeds. Reflective memory network is based on real-time characteristics, with high data transmission rate and definite response time. It is suitable for high-speed data synchronization, process control, real-time test and measurement and other fields. [0003] The reflective memory network is a high-speed, real-time, deterministic communication envir...
