The tire true roundness and wobble testing machine is a high-precision device specifically designed for the detection of roundness and wobble in tires (pneumatic tires, solid tires, and non-pneumatic tires). It uses non-contact laser measurement technology to comprehensively assess the radial runout, axial wobble, tread non-roundness, and uniformity of mass distribution of tires. This equipment is widely used in tire manufacturing, vehicle assembly lines, quality inspection centers, and research laboratories to ensure that products comply with international standards such as ISO 2309, GB/T 4502, and SAE J332, providing a scientific guarantee for the dynamic balance performance of tires and the smoothness of vehicle operation.
Application scope
It is used to simulate the fatigue test state of the brake lever of a scooter. An alternating force is applied to a fixed brake lever. After a certain number of cycles, the damage is detected. The fatigue test cycle of the brake lever during braking is automatically stopped when the set number of cycles is reached or the test piece is damaged, and the test results are retained.
Reference standard: GB/3565
Core functional modules
True roundness inspection
Radial runout measurement: A laser sensor (accuracy ±0.001mm) scans the circumference of the tire to detect the maximum radial deviation and harmonic distribution.
Axial wobble analysis: Simultaneously measures the wobble of the tire sidewall (accuracy ±0.005mm) to identify issues such as uneven installation surfaces or tire body deformation.
Tread uniformity test
Mass distribution detection: Identifies dynamic balance defects caused by uneven mass distribution through rotational centrifugal force measurement.
Tread profile scanning: A 3D laser scanner (optional) generates a tread profile cloud map to analyze the depth and symmetry of the tread pattern.
Intelligent diagnosis and correction suggestions
Data visualization: Real-time display of polar coordinate graphs, spectral analysis graphs, and marking of non-conforming areas to quickly locate defect positions.
Correction suggestions: AI algorithms recommend grinding, weighting, or structural adjustment solutions based on the inspection results to optimize the tire pass rate.
