Frequency & Damping Test Stand SAEJ2598 | FDT
High Precision Automotive Disc Brake Pad Natural Frequency and Damping Test
Brake pads are of central importance in the development and production of brake systems. The dynamic properties of the brake pads are essential characteristics for simulating the brakes during the development process or for quality control in production. The measurement of the dynamic properties (including modal values) of brake pads is described in SAEJ2598. MAUL-THEET offers a complete system that automatically carries out, evaluates and documents these measurements in accordance with SAEJ2598. With the MAUL-THEET test bench it is also possible to determine the dynamic properties (natural frequencies and damping) of other technical components.
