Damping test bench (DTS) for determining the natural frequencies and damping values as a function of temperature.
During the development and production of brake systems for the reduction of brake squealing damping materials so called shims are applied on the brake pads. For the comparison of damping characteristic of different shims test plates are measured following company internal specifications. In the most cases the results show the map of the modal damping over the frequency and temperature. MAUL-THEET offers a system that does this time consuming measurements automatically and delivers in an effective way repeatable results.
