Prepare to bring your tires and vehicles to market quicker with advanced technology provided by Calspan and LINK. Our equipment is cost-effective and engineered to meet your specific needs.
Every new piece of tire testing equipment leverages LINK’s revolutionary control and data acquisition systems running advanced algorithms perfected by Calspan over the last 50 years to generate accurate tire data.
LINK has successfully manufactured tire testing equipment for laboratories worldwide since 1935. Their vast manufacturing experience coupled with Calspan’s testing and analysis expertise creates endless opportunity for progressive testing equipment.
The Cleat and High-Speed Uniformity machine is used to assess ride and comfort for a vehicle and to generate accurate tire models. This is a special machine that is used to apply prescribed impacts onto the tire or to measure the subtle differences in ride between various tires. In both cases, the tests demand superior stiffnesses and highly sensitive instrumentation to ensure that the data are not affected by machine compliance and vibrations.
The 321 Flat Belt Machine supplies a flexible and efficient platform for tire performance characterization on a flat belt. The system combines advanced technology with proven hardware and software, resulting in dependable, repeatable, and accurate testing in support of tire development process.
Compared to existing flat-belt designs, LINK and Calspan’s 321 Flat Belt design brings three unique aspects: a hexapod tire positioning mechanism, an off-board motor, and a longitudinal slideway allowing for static testing. These distinct features result in a more capable machine that can tackle a wide range of tire testing parameters. Key features include:
The 321 Flat Belt machine achieves an accurate assessment of forces and moments applied to the tire under realistic operating conditions, but without the limitations found on many conventional force and moment machines. So not only can LINK and Calspan’s 321 Flat Belt machine conduct standard force and moment tests, it can also replicate the motion of the tire caused by suspension geometries, with the following capabilities:
Force generation is complex when the tire experiences both rotations and sliding caused by scrub radii and changing inclination angles. Modeling these forces is even further complicated when the kingpin inclination angle shifts the contact patch from one sidewall to the other during the steering event.
The 321 Flat Belt system provides the unique capability of testing the exact conditions the tire will see, long before a prototype vehicle is developed. This gives the automotive customer insight to optimally size power steering pumps and related equipment early in the design cycle.
A rolling drum type machine is used for a large variety of standard tire test procedures. High-speed uniformity, cleat and enveloping, rolling resistance, durability, and even wear tests can all be performed on rolling drum machines. Each test focuses on different aspects of the tire, so various drum machines have been designed to specialize on each type of test individually. LINK and Calspan’s All-In-One drum machine is designed as the perfect middle-ground for all these tests, offering reliable and accurate data for any type of drum test, all on one machine.
The All-In-One drum machine features two stations with differing capabilities and specialties. One station has controllable camber and steer, and the other head only controls the radial load. This way, tests that require control of camber and steer can be performed without impacting the data needed from a stiffer sensor head.
As its name suggests, the All-In-One machine can do it all! The 8-foot diameter drum reaches the perfect compromise between cyclic tests such as cleat testing, and tests that desire a flat footprint such as wear testing. The Piezoelectric station has higher stiffness, necessary for sensitive tests such as high speed uniformity. The Strain-Gauge station allows additional control for camber and steer, necessary for playback & force and moment testing.
Instead of needing multiple machines to perform a suite of tests, this machine will do everything. Some of the common types of tests this machine can perform are listed below:
Calspan, a world leader in mobility safety and performance, and Link Engineering Company (LINK), a premier provider of customized testing equipment, have joined forces to develop new, advanced technologies for tire testing. This partnership leverages decades of experience, Calspan’s expertise in tire testing and research, with LINK’s leadership in designing innovative test equipment for the transportation industry.
