& Laboratory Testing
New designs are assessed through the latest state-of-the-art Finite Element Analysis (FEA) and Failure Mode and Effect Analysis (FMEA). FEA is used to assesses strength and weight carrying capacity but also shock resistance, cornering load, kerb strike effects and beadlock forces.
Initial static laboratory testing was exhaustively undertaken at Boeing’s Advanced Manufacturing Research Centre (AMRC), Sheffield and testing continues on CBR’s bespoke test rigs as new systems are developed.
Following static trials, new system prototypes are track tested. Results are matched to FEA in order to continually improve the parameters set for FEA software in order to ensure realistic accuracy of results during design.
Third part test centres, such as Millbrook / UTAC CERAM and IDIADA are used to trial new designs prior to release for manufacture. Performance claims are based on the reports prepared by these third parties.
FEA results are analysed and components fine-tuned and re-tested until the required parameters are met.
CBR systems are tested to meet impact targets to ensure sufficient shock absorption designed to help protect vehicle suspension and to resist damage during off-road runflat.
New designs are longevity tested by a UK OEM wheel manufacturer, with minimum test runs simulating 10,000 km or more at 90mph (144kph) followed by brake and acceleration simulations to certify durability, wheel balance and reliability.
Third party testing and performance endorsement is carried out at various automotive industry test centres including, IDIADA Spain and Millbrook Proving Ground (UTAC CERAM) in the UK. Performance claims made by the Company are verifiable and out by independent test houses.
