AVL EXCITE is an innovative multi-body dynamics software solution for powertrain analysis. This simulation tool calculates the dynamics, vibration, and acoustics of combustion engines, transmissions, and complete ICE-based or electrified drive units. It enables users to model, simulate, assess, and optimize structural dynamics, NVH (Noise, Vibration, and Harshness), and durability of all types of propulsion systems, enhancing driving pleasure, passenger comfort and safety. By incorporating elastic components and nonlinear contact points, EXCITE accurately predicts noise excitation and radiation, ensuring component strength, lifetime, and precise noise prediction. Different modeling depths offers balance accuracy and simulation time for specific application goals. Features:

• Simulates dynamics of different gear stages, planetary gear sets & e-motor types for e-axis systems, optimizing for NVH, durability, and manufacturing tolerances.
• Analyzes tribological influences (friction, lubrication, wear) to increase durability of bearings & components while reducing energy consumption.
• Calculates structure-borne & airborne noise of powertrain units, using tools like ODS, NTPA, and MCF to identify sources of excitation & vibration.
• Provides a reliable solution for 3D piston ring simulation, analyzing ring deformation's influence on blow-by, friction, wear, and oil consumption.
• Offers a multi-level approach to modeling, balancing accuracy with simulation effort & time for components, subsystems & complete drive units.
