Radial Fatigue Testing

Wheel Testing Services - Independent Test Services - RADIAL_FATIGUE_TESTINGITS has radial fatigue stations capable of testing from 300-38,000 lb test loads, in sizes from 10”-26” diameter. Variable speed capability allows us to balance test time with tire life. We have recently added a two-station machine that is capable of 38,000 lbs on each station.  The machine uses lower speed, tire cooling and high load capacity for super single wheel testing.

Biaxial Fatigue Testing

Wheel Testing Services - Independent Test Services - BIAXIAL_FATIGUE_TESTINGITS has four Biaxial Fatigue test machines equipped to test wheels, spindles, hubs and bearings. Having co-developed the SAE J2562 passenger car and light truck load files, our experience includes developing sports car wheels, forensic evaluation of wheel fastening systems and A-to-B comparison testing to find inboard flange hacksaw cracks.

Uniformity & Static Imbalance Testing

Wheel Testing Services - Independent Test Services - UNIFORMITY_%26_STATIC_IMBALANCE_TESTINGUniformity analyzers measure the radial and lateral runout. Radial run-out is the difference between the high spot and the rim average on the outer or inner wheel rim. It is best measured at the bead seat.  Lateral runout is the side-to-side wobble of the wheel on the outer or inner rim. Too much runout in either case can cause noise and handling issues.

Motorcycle Wheel Testing

Wheel Testing Services - Independent Test Services - MOTORCYCLE_WHEEL_TESTINGITS can conduct all four standardized motorcycle wheel tests to JASO T 203-85. The cornering and radial fatigue tests are comparable to those used on passenger cars along with the torsion test required in the specification. A radial impact test is also specified requiring striker geometry drop height and fixturing of the wheel that makes the test unique.

Fastener Testing

Wheel Testing Services - Independent Test Services - FASTENER_TESTINGWe have a torque tension rig set up to accommodate a number of fastener tests. Most fastener tests set out to prove the fastener joint works as intended for the life of the wheel, even after the tires have been rotated or other maintenance has been performed.

Strain Gauge and Data Acquisition

Wheel Testing Services - Independent Test Services - STRAIN_GAUGE_AND_DATA_ACQUISITION

When it comes to technology, ITS has found a way to incorporate the latest and greatest into our testing capabilities. Strain Gage Application and data acquisition can be done in-house which allows for more customization and faster turnaround time. Data acquisition is done either wirelessly or through a slip ring.

Videography/Photography

Wheel Testing Services - Independent Test Services - VIDEOGRAPHYPHOTOGRAPHYHigh-speed video up to 240fps and up to 4 angles can be used to better understand test phenomena. We have light banks and rigging to capture all sides of a test. High-speed video is especially useful for impact testing because you can slow it down and see each step of the impact event in detail.
