Simcenter Amesim

Simcenter Amesim supports early design phases by allowing you to create simulation models for range and performance. It also enables you to create advanced vehicle energy management models, including predictive dynamic modeling of the engine, powertrain, battery, heating, ventilation and air conditioning (HVAC) and all associated thermal management systems for any kind of vehicle, be it conventional, hybrid or electric.The software also helps you win the electrifi-cation race by providing the appropriate tools to embrace this technology evolution. To manage the complexity that comes with introducing a new energy source into the vehicle, Simcenter Amesim offers state-of-the-art multilevel modeling for all critical subsystems, such as internal combustion engine, electric machine, battery and trans-mission. On top of that, it supports your integration processes by delivering the best-balanced design in terms of energy efficiency, performance and drivability for any kind of powertrain architecture.

To prepare for vehicle integration, Simcenter Amesim comes with a large set of application-oriented capabilities that help you size components and optimize subsystem efficiency. Simcenter AMESIM in Automotive industry applications are:

  • Electrified Powertrain - Master the engineering complexity of vehicle electrification. Whether you deal with architecture definition, battery sizing or electric machine design, benefit from efficient modeling work-flows to design and validate subsystems and their integration.
  • Internal combustion engine design and controls - Optimize complete ICE systems, from air management and combustion to exhaust after-treatment. Develop physical plant models to support engine controls development and validation. Study engine integration in a full powertrain and vehicle context.
  • Fuel Injection - Enhance the injector design to minimize the activation energy, perform the proper needle lift and achieve the right fuel delivery.
  • Lubrication - Compute flow rates and energy losses by simulating the integra-tion of hydraulic (pumps, bearings) and mechanical subsystems (crankshafts, camshafts). Analyze pressure dynamics and ther-mal aspects relative to the oil circuit.
