CHIP&CUT Analyzer

The device is used to characterize dynamic, fatigue as well as quasi-static rubber abrasion with dynamic forces in the variable frequency load band. Dynamic forces are derived in two perpendicular directions for characterizing both normal and frictional forces The measuring principle of the device is based on the rotating test body of the variable geometry in the required  range  with dynamic forces being exerted  by the linear drive in the normal direction to the rotating test body while maintaining the constant load force in the normal direction according to a given value overa defined load cycle time The device mainly serves to describe the dynamic abrasion known as Chip & Cut occurring in heavy-duty truck tires, as well as quasi-static abrasion to determine the coefficient of friction Basic device parameters: Realizable Load Modes: Dynamic Cycle Scraping and Quasi-Static - Permanent Scruff Speed ​​range freely selectable in the range of 100 1400 rpm with 1 rpm accuracy Measuring range of normal force ± 500N, - measuring range of normal force ± 900N, Load frequency up to 10 Hz Minimum penetration time and dynamic abrasion adjustable in the range from 20 ms
