Durability and NVH

EXCITE has been chosen by the majority of engine manufacturers worldwide as their main platform for strength and durability and NVH simulations of power units, making it the leading software on the market for durability analysis of engine components, valve train and timing drive dynamics, tribological analysis of engine lubricated contacts, cylinder kit design and NVH optimization.

Real life conditions for precise results

EXCITE calculates complex dynamic models considerably faster than multipurpose tools. Short turn around times are achieved by robust and optimized solvers even with complex models. The accurate consideration of non-linearities in engine lubricated contacts provides results close to the real ones. Thus the simulation efficiently helps the engineer to make the right design decisions and facilitates the reduction of costly testing essentially.

Powertrain oriented solution

Powertrain analysis specific workflows and automated model generation and result evaluation capabilities help the engineer to reach short project lead times. For example, EXCITE AutoSHAFT is a significant time saver for crankshaft model generation. Based on files from CAD, a dynamic crankshaft model can be generated within hours. EXCITE calculates transient engine run-up and in-stationary conditions without relying on unrealistic speed steps. Thus critical operating conditions can be reliably detected without time-consuminginterpretation of incomplete results.

Multi-level simulation models

Different modelling levels for single components as well as for the entire system help the engineer to use an optimum balance of model depth in terms of required accuracy for the application target and the modelling and simulation time. The simulation models can be extended as needed during the development process, saving costs by eliminating the need to rebuild models for each step.

Integration and customization

Interfaces for 3rd party FE and fatigue software enable the seamless integration of EXCITE in the customer CAE environment. With the integrated finite element solver from ABAQUSTM the application workflows for stress and NVH analysis can optionally be covered completely by EXCITE. For extensive design variation, parameter identification and optimization tasks interfaces to commercial optimization software are provided. Customer definable template models, plot and report generation, workflow descriptions and a customizable GUI make the usage of detailed models easier and support the adjustment of EXCITE to customer specific requirements and workflows.
