Appendix 4: Abaqus-EXCITE Workflow45 minutesLesson content:IntroductionAbaqus-EXCITE WorkflowAbaqus-EXCITE-Abaqus WorkflowIntroduction (1/3) Abaqus FEAAbaqus is suite of a general-purpose finite element analysis softwareThe Abaqus suite delivers accurate, robust, high-performance solutions for challenging nonlinear problems, large-scale linear dynamics applications, and routine design simulationsAVL EXCITEAVL EXCITE is a specialized tool used to perform multi-body simulations for durability and NVH (Noise Vibration and Harshness) analyses of automotive power units and drive linesAbaqus and AVL EXCITE can be used together to take advantage of the strengths of both toolsThis combination is used in the automotive powertrain analysis community for engine design and NVH simulationIntroduction (2/3)AVL EXCITE Power Unit is used for:NVH of Power Units Durability of Engine ComponentsAdvanced Bearing DesignThe nonlinear bearing forces and moments can be calculated due to actual dynamics of the assembled multi-body systemAbaqus can provide the AVL EXCITE Power Unit with substructures (i.e., linear elastic bodies) Such as engine block, crankshaft, conrod, etc.Generated substructures can Include Nonlinear preloading effectsLoad casesAVL EXCITE model (2D-View)Crankshaft SubstructureIntroduction (3/3)Advantages to including Abaqus in AVL EXCITE workflows:Stress Models for DynamicsAbaqus stress models are created with advanced nonlinear featuresLarge-scale linear dynamics in Abaqus is fully integrated with nonlinear offeringUse a singe Abaqus model for both stress analysis and dynamic simulationsOne model for multiple uses reduces model generation effortPerformanceAbaqus linear dynamics is on par with best-in-class commercial linear dynamics solversMode extraction using parallel AMS eigensolver for inclusion in substructure generationExternal data recovery using parallel AMS and parallel steady-state dynamicsAbaqus-EXCITE Workflow (1/20)The SIM (.sim) file for an Abaqus substruct
