AVL EXCITE™ Acoustics by AVL Airborne Noise Calculation EXCITE™ Acoustics is a tool for the calculation of sound radiation in free field from vibrating structures such as engines and power units using the Wave Based Technique (WBT). It seamlessly fits into the EXCITE™ structural dynamic analysis workflow as the final step of acoustic analysis, using the FE mesh of the structure and the surface velocity results as input. With interfaces to common FE tools for the import of the vibrating structure geometry and the surface velocity boundary condition, EXCITE™ Acoustics can also be used as a standalone EXCITE™ tool. Benefits Fast and flexible post-processing Product Highlights microphone positions and field point meshes Meshing of the acoustic model starts from can be added or modified without unmodified FE mesh used for the structural recalculation of the sound radiation • Starts from unmodified structural vibration analysis finite element mesh no need to close smaller openings, to Features change element types • Automated generation of acoustic Meshing tool mesh with model preparation Fully automated generation of the acoustic for automated generation of the acoustic complete in just a few clicks mesh with interactive 3D viewer WBT mesh easy and fast preparation of the calculation • Applies on model for the entire model with a few clicks Various interfaces to import geometry and frequency range surface velocity boundary conditions of the Acoustic mesh is not frequency dependent vibrating structure • Subsequently definable post- accurate results with one model for the geometry - EXCITETM (.meg), Abaqus® (.inp), processing whole frequency range, high computational ANSYS (.rst), MSC Nastran® / NX Nastran® performance due to small acoustic models (.bdf, .op2), OptiStruct® (.op2) • Integrated with OptiStruct surface velocities - EXCITETM (.mer), Audible results Abaqus® (.odb), ANSYS (.rst), MSC direct assessment of noise characteristics by Nastran®/ NX Nastran® (.pch, .op2), hearing comparisons OptiStruct® (.op2) Learn more: altairhyperworks.com/partner/EXCITE-Acoustics Short analysis lead times from model 3D pre-processing viewer preparation till result evaluation for visualization of the acoustic meshing step results with interactive capabilities for AVL develops and improves all kinds of the company operates globally to serve optional mesh modifications powertrain systems and is a competent customers in a diverse range of industries partner to the engine and automotive including automotive, aerospace, defense, Optional constant or frequency dependent industry.
