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
  • Determination of dynamic effects, forces and loads
  • Investigation of interaction effects with valve train and crank train excitation
  • Single component and layout optimisation
