Product Category: Laboratory Testing

High Dynamic Oscillation Tester HDOT is a system to measure the transient response of treadrubbers on different friction-/ road surfaces. It is based on the customers experience with the HSLFT and advanced customer needs. Geometrically standardized rubber samples are activated with high frequency in various loading conditions, bi-axial in longitudinal and vertical direction. Road surfaces and samples are replaceable and free to configure and may be conditioned with various temperatures. This machine opens complete new opportunities to describe the material properties of elastomers.

The HSLFT offers a unique possibility to determine the friction coefficients of rubber samples on different surfaces and under various operating conditions in order to predict compound and pattern influences on the grip and traction performance of tires. Reproducible ice and snow conditions transfer expensive winter tests into the lab.
