An Integrated Platform for Collaborative Simulation and Fault Diagnosis

Before application to real manufacturing, thorough evaluation of working performance and the fault diagnosis strategy is absolutely necessary. A comprehensive multifunctional simulation platform based on collaborative simulation and fault diagnosis is presented. Based on virtual prototype, database, network communication and fault diagnosis technologies, the platform allows users to model in a structural and hierarchical way, study the behaviors of individual components and the interaction of subsystems, as well as adjust the fault diagnosis solutions in a simulation environment. An integrated framework is developed to manage the model databases, assemble the models, run the simulation application and display the simulation result. An embedded fault diagnosis module which can help users have a good command of fault recovery is employed to verify the reliability of fault diagnosis solutions. The developed integrated platform is shown to be a valuable tool both for performance simulation and fault diagnosis education. A case of a large-scale erecting vehicle has been introduced to demonstrate the concept
