Wheel Lab / Development

BBS Wheel Lab explores the load path

Materials, simulation and physical testing are most useful when they answer the same engineering question.

Wheel simulation and test

From a model to a measurable result

A digital model can help identify areas to investigate, but its value depends on the boundary conditions and material assumptions supplied. We start by identifying the vehicle interface and loads, then define what a prototype or rig test must establish. Simulation and physical evidence can inform one another as the design evolves.

“A useful test begins with a clear question.”

Forged wheels may suit low-volume programs seeking strength-to-weight efficiency and custom dimensions, while cast or flow-formed designs may offer complex shapes and economies at production scale. Tooling investment, lead time and inspection requirements vary with the design; neither process guarantees a particular mass or fatigue life. No reduction in mass or increase in life is assumed without a defined baseline and test method.

Questions for the lab

Record material properties, mounting conditions and representative loads before modeling. Identify the sample revision, fixture, load sequence and acceptance criteria in the test plan; compare measured results with predictions and revise assumptions when they diverge. Results apply only to the tested design and conditions.

Sensor integration begins with packaging, environmental exposure and interface requirements. Any sensing concept needs validation in the intended vehicle and duty cycle.

Results are compared with the agreed acceptance criteria and sample revision. Findings can lead to a design change, further testing or a documented release decision.

Inside the development loop

Material evaluation, numerical analysis and test fixtures each contribute different evidence. The program team decides how these methods apply to the wheel, target market and intended use.
