An important design task of gearbox development is the optimization of its lubrication across a wide range of operating conditions, lubricant viscosities, oil fill levels, vehicle grades and dynamic maneuvers. Industry-wide, a drive to digitalize testing means that new CFD methods are required to economically reproduce this task in a virtual environment.

These requirements have driven the market to consider particle-based CFD simulation methods, which are particularly well suited to handle free surface flows involving complex geometries. PreonLab is one such particle-based CFD code based on implicit incompressible smoothed particle hydrodynamics. PreonLab offers a uniquely efficient simulation tool that enables transient simulation of real-world scenarios such as monitoring lubrication in e-drive gearboxes.

Key topics and takeaways:

• See how PreonLab handles complicated geometries, such as housings, hollow shafts, and planetary gearsets
• Learn more about fluid particle refinement and non-uniform particle sizes
• Experience the simplicity of meshless design variants and operating condition sweeps
• Review typical simulation results
Compare to traditional testbeds: see how to use transparent housing to validate models, then use models to validate variants
