ICE Dynamics, Strength and Durability Simulation

Today's trend in internal combustion engine (ICE) design is to achieve more power while downsizing and reducing the weight of the engine, thus reducing fuel consumption and CO₂ emissions. However, this is also accompanied by higher mechanical and thermal loads on the engine components. It is therefore necessary to go closer to the limits of strength and durability.

The Optimal Solution for All Phases of the Development Process

Our solution has proven itself for all engine sizes, from small single-cylinder engines to large marine diesel engines. From concept to layout to the final design phase. Thanks to the different modeling levels for single components as well as for the entire engine, you work at the optimal modeling depth in every phase of the engine development process.

By using our tools, you can cover all tasks of the design phase of an internal combustion engine: Single valve train dynamics, ICE torsional vibration, flywheel inertia design and TVD parameters, basic crankshaft strength and bearing analysis, and engine suspension design. The short calculation times are optimal for your parametric studies, Design of Experiment (DoE) and optimization. A smooth transition from concept to detailed design analysis is ensured by shared model input and FE data, common GUI and post-processing.

Ensure the Mechanical Reliability of Your IC-Engine

The detailed design analysis of components and subsystems allows you to consider the entire combustion engine dynamics. For cranktrain durability calculations, various modeling levels and workflows for stress and fatigue evaluation are integrated into the analysis solution. Using elastohydrodynamic (EHD) contact models, you can take into account the interaction between oil film pressure and component deformations under transient dynamic loads. (For hot components such as the piston, the analysis workflow additionally incorporates the temperature field of the piston from the thermal analysis into the stress and fatigue analysis).
In the same way and at the same level of detail, you can also examine the dynamics and durability of the other ICE subsystems such as the valve train, timing and accessory drives, and turbocharger. Which allows you to ensure the reliability of the engine.
