Rubber Rolling Resistance Testing Machine

Rubber Rolling Resistance Testing Machine
A specialized instrument designed to measure the rolling resistance of rubber materials—primarily tires and rubber compounds—quantifying the energy lost as a rubber sample rolls against a surface under load. Rolling resistance directly impacts fuel efficiency, battery life (in electric vehicles), and operational costs, making this tester critical for optimizing rubber formulations and tire designs.

 

Equipped with a rotating drum (simulating road surfaces), precision load cells, speed controls, and temperature regulation, the machine operates by:

 

  • Mounting a rubber sample (e.g., a tire tread segment or full tire) against a rotating drum.
  • Applying a vertical load to simulate vehicle weight and controlling drum speed to replicate driving conditions (e.g., 30–120 km/h).
  • Measuring the force required to maintain rotation, calculating rolling resistance as a coefficient (CRR, Coefficient of Rolling Resistance) or energy loss per distance.

 

Key applications include testing:

 

  • Tire Manufacturing: Evaluating tread compounds to reduce rolling resistance for fuel-efficient or low-emission tires (aligned with global regulations like EU tire labels).
  • Rubber Compounds: Optimizing elastomer formulations (e.g., adding silica or specialized polymers) to balance rolling resistance with traction and wear.
  • Automotive R&D: Validating tire performance for electric vehicles (EVs), where lower rolling resistance extends battery range.

 

Compliant with international standards such as ISO 28580, ASTM F1816, and EU Regulation 1222/2009, this machine is trusted by tire manufacturers, rubber suppliers, and automotive engineers. It provides data to meet regulatory requirements, improve sustainability, and enhance end-user value—from reducing carbon footprints to extending EV driving range.
