Streamline your Structure Dynamics Simulation
AVL EXCITE™
Multi-Body Dynamics Simulation Software
The Challenge
Strength and durability
- How can I reduce the weight of my powertrain without exceeding the limits of component strength and durability?
- Is it possible to start with simplified models (rigid MBD) and progress to detailed models (flexible MBD)?
Lubricated sliding contact analysis
- Can I include all relevant physical properties of materials and lubricants to optimize the performance of bearings, pistons and piston rings?
- Does the simulation include support for the investigation of wear or failure?
- How to derive accurate friction data to support engine and powertrain efficiency enhancement?
Noise, vibration and harshness (NVH)
- How can I determine dominant noise sources and derive measures to improve the acoustic behaviour?
- Can the interaction between sub-systems (engine, transmission, driveline) be taken into account?
- How to calculate airborne noise to compare with measurements?
The AVL Solution
AVL EXCITE™ is used by OEMs and tier 1s to improve product performance, reliability and safety.
The use of various model depth levels ensures an optimum balance between modeling, simulation effort and accuracy from concept via layout to the final design phase. This includes detailed elasto-hydrodynamic contact models for all slider and thrust bearings in the cranktrain and the piston/piston ring-liner contact.
AVL EXCITE™ allows a significant reduction in development time and costs to be achieved with the support of powertrain analysis specific workflows, automated model generation and result evaluation capabilities.
Seamless integration in the customer’s CAE environment is supported via 3rd party software interfaces and an API and user-definable template models, result reports and workflow descriptions enable to customize the usage of the software.
The Added Value
- One simulation environment for all phases of the engine development process and for all structural dynamics related analysis tasks
- Shaped by AVL's 60+ years of leadership in engine and powertrain engineering consultancy
- Dedicated user support and guidance teams around the world with AVL engineers who are highly experienced in engine analysis
AVL EXCITE™ Simulation Tools
AVL EXCITE™ Designer
AVL EXCITE™ Designer uses efficient numerical methods to enable fast and realistic dimensioning of crankshafts, powertrains and drivelines already in the early concept phase of the development process.
AVL EXCITE™ Power Unit
AVL EXCITE™ Power Unit is a highly advanced multi-body dynamics solution for calculating the dynamics, strength and acoustics of combustion engines, transmissions and powertrains. The system approach and accurate results enable designs close to endurance limits and to calculate structure-borne noise levels close to reality.
AVL EXCITE™ Acoustics
AVL EXCITE™ Acoustics is a new tool of the EXCITE™ product family for the calculation of sound radiation in free field from vibrating structures such as engines and power units using the wave based technique (WBT).
AVL EXCITE™ Timing Drive
A flexible and modular system makes AVL EXCITE™ Timing Drive an ideal, easy-to-use tool for standard applications as well as for detailed investigations of valve trains and timing drives. It covers the entire workflow starting from kinematic design of cam profiles up to the dynamics of entire timing drives.
AVL EXCITE™ Piston&Rings
AVL EXCITE™ Piston&Rings is an efficient tool for sizing piston ring assemblies. It calculates absolute values for inter-ring pressures, piston ring movements and blow-by and delivers reliable trends regarding lube oil consumption.
AVL Design Explorer™
Design Explorer is an integrated tool of the AVL simulation environment, which provides an easy to use workflow to define, run and evaluate DoE and optimization tasks. It is a user-friendly and cost-efficient solution to investigate the dependencies between model parameters and simulation results and to improve the quality of the design by using one of the optimization algorithms.
