Research Of Multidisciplinary Flow Distributed Scheduling Based On DDS

The overall analysis of complex mechanical systems often includes multi-disciplinary analysis,such as structural stress analysis,dynamic analysis,aerodynamic analysis,etc.In order to achieve the complex mechanical system modeling and simulation analysis,we need to build a multidisciplinary integrated modeling and simulation platform for the interdisciplinary analysis focused on the unified environment.In order to achieve the integration of different disciplines resources under the network environment.In order to improve the simulation efficiency of overall system at the same time,we need carry out a research of multidisciplinary flow distributed Scheduling.Based on the multidisciplinary integrated modeling and simulation platform FlowComputer,this paper studies the model of Multidisciplinary Flow Distributed Scheduling based on DDS.We will carry out multidisciplinary flow distributed Scheduling system under FlowComputer based on MFDS-DDS.The work of this paper can improve the multidisciplinary simulation ability of FlowComputer,and also improve the software's flexibility,widens the application scenarios of the software.The main work is as follows:1.This paper introduce the common multidisciplinary process modeling and simulation technology.We discuss the internal demand of distributed Scheduling services in a multidisciplinary modeling simulation software.With the comparing of many distributed Scheduling environment,for example LSF,RMCL and DDS,we decide to develop the model of MFDS-DDS and carry out the distributed Scheduling system under FlowComputer.2.This paper has carried on deep discussion on the basic framework of DDS,the base application modeling of DDS,the data transmission mode,the QOS,the common communication model.We will achieve the MDFC-DDS based on the study of DDS.This paper describes the data transmission process of MFDS-DDS.3.The latter part of the this paper describe the main work of this subject.The key technology of distributed Scheduling services based on MFDS-DDS,including DDS embedding?and distributed component encapsulation based on DDS?distributed flow running based on DDS.At the end of this Paper,we achieve a multidisciplinary process distributed Scheduling system based on MFDS-DDS model under the plat ofFlowComputer.The operation of the Scheduling system is demonstrated through an example.
