- AVL EXCITE™ is an innovative rigid and flexible multi-body dynamics software solution for powertrain analysis. This powertrain development tool calculates the dynamics, durability, vibration and acoustics of combustion engines, transmissions and entire ICE-based or electrified powertrains.
AVL EXCITE™ is a simulation tool that supports the modelling of components, subsystems and complete powertrains with different levels of detail. This is adapted to analysis demands, ensuring an optimum balance between simulation effort and accuracy.
Detailed thermal elasto-hydrodynamic contact models (EHD) for slider bearings, pistons and piston rings, and 3D gear contact models with the real tooth profiles are provided. This facilitates in-depth investigations with accurate results for durability, friction, wear and acoustics. The best possible computational efficiency is achieved by a strong numerical coupling between structure dynamics and elasto-hydrodynamics.
For a detailed analysis all components must be presented by flexible components, whereas all properties such as structural matrices are derived by a powerful substructure generation step and outputted in a native EXCITE format directly in Abaqus.
Besides the vibration results obtained by a transient non-linear analysis in AVL EXCITE™ can be recovered very efficiently with the tool ‘abaqus substrcuturerecover’ to the original FE structure to get accurate stress results for fatigue assessments or surface velocities for further airborne noise calculations.
- AVL FIRE™ is the leading computational fluid dynamics (CFD) simulation package for the development of ICE-based and electrified propulsion systems.
Designed to accurately simulate relevant physics and chemistry, it has a wide range of uses. These include the modelling of electrochemistry and thermal behaviour of batteries and fuel cells and the prediction of processes relevant to the combustion engines.
Through automated pre-processing computational models are generated without effort, even those including moving parts such as shafts, gears and pistons.
The main program offers grid independent heat transfer modelling, turbulence modelling accounting for the complexity of flows in powertrain components, Lagrangian and Eulerian multiphase capabilities dedicated to FIRE™’s key applications and in-depth modelling of reaction-chemistry and electro-chemistry.
The integrated postprocessor offers online monitoring and result analysis.
To conclude about the impact of the heat transfer between fluid and solid on stresses and deformations of the structural parts in the powertrain, AVL FIRE™ offers an interface (CSE) to Abaqus.
