Description
Aegys Dynamics is an iterative wear-prediction code developed for connecting-rod journal bearings operating under severe mixed-lubrication conditions. The solver couples MATLAB with GT-Suite v2023 to perform step-wise elastohydrodynamic (EHD) simulations, updating bearing clearance after each wear increment. The algorithm incorporates a multi-criteria adaptive time-step selection, dynamic roughness variation based on real data and a non-local averaging method to stabilize wear evolution and accurately capture seizure-prone regions. Based on Archard-type formulations and interface variables computed in GT-Suite, Aegys Dynamics predicts wear depth over quasi-transient operating cycles where speed, temperature and load evolve.
This code can be used for lubricant formulation assessment, bearing design studies, parametric analyses, and research on mixed-lubrication wear mechanisms in high-power-density engines.
