Pendulum Impact Elasticity Tester China Supplier
Rubber Rebound Resilience Tester is designed to determine the rebound resilience of rubber, flexible cellular materials, thermoplastics, elastomers, soft elastic foams subjected to impact by a pendulum from a specified height, to obtain the optimum applicability, the quality differentiation of various materials, and changes of characteristics after the aging test, etc. The rebound resistance test is an effective method to get quality assurance during the rubber production process or on the finished products.
When the elastomer is struck by an external force, an energy input is involved, some of which is returned when the rubber returns to its original state. The rest energy which is not returned is dissipated as heat in the elastomer. The ratio of the energy returned to the energy exerted is called resilience. When the deformation is an indentation due to a single impact, this ratio is referred to as rebound resilience. The rebound resilience value is not always constant for one material due to variations of testing temperature, strain distribution, strain rate, strain energy and strain history.
Test Principle
A test piece with the plane and parallel surfaces clamped into the rebound resilience testing machine is impacted on one surface by a pendulum with a spherical end from a defined height. The rebound resilience is evaluated by measuring the energy of the impacting mass immediately before and after impact.
