Static and dynamic tests

STATIC AND DYNAMIC TESTS

OZ's Quality Control tests:

• Chemical analysis on raw materials and castings
• Ultrasonic Inspection to reveal defects and impurities
• Air Tightness to identify any air leaks caused by porosity (wheel submerged in a tub of water, air enjected under 5-7 atm)
• Dye Penetrant Inspection to identify any superficial cracks or microfaults (chromatic contrast under UV light)
• Fatigue test wheel subjected to the same mechanical stress of a car driving along a bend
• LBF Biaxial Wheel Testing Machine
• Rolling test simulates the behaviour and reactions of the wheel along a straight stretch(maximum load, 100 km/h)
• Impact test (crash test) simulation of stresses that the wheel might suffer on the road
• Dimensional check to assess the dimensions, circularity and concentricity of the wheel (tolerances of a few tenths of mm)
• X-ray control
