BEYOND MODELLING
UNDERSTANDING BEARING BEHAVIOR, EVEN UNDER EXTREME CONDITIONS
NO BLINDSPOT
THE APO-GEE METHOD
​We follow a specific analytical approach, unique in the world, in conjunction with our original set of tools (ROSE), to characterize the ball kinematics and the bearing behavior.
The APO-GEE's method is a physics-driven engineering approach focused on understanding the fundamental mechanisms behind bearing behavior rather than pure simulation.
The method identifies the key physical phenomena that govern performance or failure, and then develops innovative design solutions based on these core principles.
This approach emphasizes understanding and the search for robust, generic improvements that remain effective across varying operating conditions.
The APO-GEE's methodology enables efficient innovation, faster problem solving, and practical engineering breakthroughs in complex systems.
Our Breakthrough: Power-Based Equilibrium
We do not rely on a traditional or specific Newtonian formalism framework.
We use a fundamentally different approach.
At the core of APO-GEE’s methodology lies a new equilibrium criterion: power.
This enables the complete computation of ball kinematics, giving access to the true equilibrium of the bearing and resolving configurations that were previously unsolvable.
No blind zones.
ROSE: APO-GEE’s computational engine
We have developed ROSE, our set of computational tools, alongside our methodological approach.
ROSE fully computes the kinematics of the rolling elements with unmatched precision, providing access to key internal variables.
This enables a reliable and robust characterization of complex bearing phenomena.
However, unlike classical approaches, ROSE incorporates a new variational formulation that notably removes common hypotheses and naturally captures the underlying physics governing bearing behavior.
One module of ROSE is specifically dedicated to cage dynamics analysis, enabling for instance the detection and characterization of sudden friction torque increases driven by cage instability and ball speed variation.
From Theory to Industrial Impact
​​Our methodology and tools go beyond theory.
They are implemented, validated, and applied to real engineering challenges.
They have consistently delivered actionable insights, supporting innovative product development such as the Butterfly cage and the Cobweb bearing, advanced diagnostic capabilities, and the implementation of concrete solutions.
Not just simulations.
This is particularly critical for bearing configurations operating at the limits of performance, such as in aerospace and defense mechanisms, high-speed spindles, high-end motorsport, and other highly demanding industrial applications.
