SIMPACK Engine Chain
SIMPACK ENGINE CHAIN is an add-on SIMPACK module which enables an easy, quick, accurate and reliable model setup and analysis of engine timing chain models.
Model setup with SIMPACK ENGINE CHAIN can be done comfortabe using a well thought-out chain model pre-processor including complete chain model generation and setting of initial conditions. Various chain types and high levelled modelling features like a sophisticated hydraulic chain tensioner model, flexible chain guides, flexible shafts, elastic bearings, noncircular chain wheels and comfortable valve train/crank train excitation definition are available. Verified models can be directly used in complete engine models with coupled crank train and/or valve train interaction.
Applications
- Chain drive layout design
- Resonance analysis during run up
- Single revolution speed analysis
