Dynamics of Power Units Market DriversThe dynamic behavior of the powertrain system and its individual components has a major impact on durability and acoustics. A primary objective of powertrain development is to minimize vibrations. This can only be achieved if the vibration behavior of individual components and the entire system is analyzed.
In order to render the development process as efficient as possible, problems that might appear, such as vibrations and resonances, have to be determined early on and eliminated. For this purpose, simulation models are used that represent the load conditions as realistically as possible. If the prototype is optimized in the simulation domain, time and costs can be saved on the test bed.
AVL Approach- Specialized solutions for subsystems
- Different mathematical approaches for the stages of analysis: analytical solutions, rigid and FE-based flexible multi-body solutions
- Capability to connect detailed sub-models for entire system analysis, including co-simulation (e.g. crank and valve train coupling via EXCITE Power Unit and EXCITE Timing Drive)
AVL EXCITE Strengths- EXCITE offers a complete solution for the evaluation and analysis of the engine and transmission dynamics
- Component library provided to expand the analysis from the transmission to the entire drive line (gears, roller bearings, axial thrust bearing)
- Capability to track global transient events for the cranktrain, transmission and driveline (e.g. tip-in / tip-out, shift, launch)
Your Benefits- One simulation environment for the analysis of all power unit components
- Multi-level approach – modeling depth adjustable to application target
- Accurate calculation of dynamic loads and responses
- Comprehensive analysis of influencing design parameters and their interference
- Investigation of interaction between system components/subsystems through analysis of entire systems
