Pendulum Friction Coefficient Tester

With the development of the transportation sector, the issue of skid resistance on road surfaces—such as highways, urban streets, and airport runways—has attracted widespread attention from relevant authorities. The pendulum friction coefficient tester (hereafter referred to as the pendulum tester) is an instrument used to measure the friction coefficients of road surfaces, airport runways, pavement markings, and similar materials. It can also serve, through the measurement of typical pavement friction coefficients, as one of the bases for determining optimal tire formulations. This instrument is easy to calibrate and simple to operate; it has minimal impact on traffic during testing, yields relatively stable data, and can be used both indoors and outdoors. Principle: The pendulum tester is a dynamic pendulum‑impact type device. It is designed based on the fundamental principle that “the loss of potential energy of the pendulum equals the work done to overcome friction between the rubber pad mounted at the end of the pendulum arm and the road surface as the pad slides across it.”

Description

Product Introduction:

With the development of the transportation sector, the issue of skid resistance on roadways, urban streets, and airport runways has garnered widespread attention from relevant authorities. The pendulum friction coefficient tester (hereafter referred to as the pendulum tester) is an instrument used to measure the friction coefficients of pavements, airport runways, pavement markings, and similar surfaces. It can also serve, through the measurement of typical pavement friction coefficients, as one of the bases for determining optimal tire formulations. This instrument is easy to calibrate and simple to operate; it has minimal impact on traffic during testing, yields relatively stable data, and can be used both indoors and outdoors.

Principle

The pendulum tester is a dynamic pendulum‑impact instrument. It was developed based on the fundamental principle that “the loss of potential energy of the pendulum equals the work done to overcome friction between the rubber pad mounted at the end of the pendulum arm and the road surface as it slides along the pavement.”
