Research and Application on Fault Simulation Technology Based on Virtual Prototype
Aiming at the present application of fault simulation technology based on virtual prototype,virtual prototype technology and fault injection technology were studied and analyzed,and the fault injection technology was improved.Taking a mechanical system as research subject,the mechanism of fault caused by a springs fatigue failure was analyzed.The systems dynamic response of different fault phases was analyzed based on the systems virtual prototype.Finally,the occasion of fault occurrence,springs stiffness dropping to between 90% and 91% of primary value,is confirmed.The simulation result provides characteristic information for preventing and diagnosing fault.
