ENGDYN
is a dedicated three-dimensional engine analysis tool essential to the design and development of the crank train, engine structure and associated components such as bearings, connecting rods and engine mounts. By offering a range of levels of complexity of components, oil film models and solvers, ENGDYN can be used throughout the entire development programme, from concept through to production.

Applications

  • Range of Solutions - ENGDYN has been desinged to be used throughout the engine design programme-from the early concept studies right through to detailed investigations of fully dynamic systems.
  • Bearing Analysis - coupling the crankshaft and cylinder block dynamics with the bearing oil film to allows the user to perform a range of analyses to aid bearing design.
  • Crankshift Analysis - ENGDYN provides two methods of solution for predicting crankshaft durability, incorporating both a classical approach using simple beam theory as well as a more advanced finite element approach for more definitive studies.
  • Cylinder Block Analysis - the solution provides all of the loads required for the concise analysis of the powertrain structure.
  • Noise and Vibration - an advanced NVH post-processor is incorporated which allows the user to back-substitute the ENGDYN solution onto a three-dimensional FEA model of the powertrain or ancillary components and to predict nodal vibrations in the structure.
  • Connecting Rod Analysis - the simulation can incorporate a range of connecting rod models from a simplified rigid representation through to fully three-dimensional compliant or dynamic models. By default ENGDYN simply applies loads to the crank-pin and cylinder assuming primary motion.
