IMPROVEMENT OF THE DIGITAL DISPLAY OF COEFFICIENT OF SLIDING MEASUREMENTS AND DETERMINATION AND RECORDING OF SPEED

VERBESSERUNG DER DIGITALEN MESSWERTANZEIGE DES GLEIT- BEIWERTES SOWIE BESTIMMUNG UND REGISTRIERUNG DER FAHRGESCHWINDIGKEIT

IN ORDER TO REDUCE THE TIME-CONSUMING WORK OF EVALUATING RECORDED VALUES IN THE DETERMINATION OF THE COEFFICIENT OF SLIP WITH THE STUTTGART FRICTION METER, THE DISPLAY IS TO BE DIGITALIZED. THE FOLLOWING REFINEMENTS AND MODIFICATIONS SIMPLIFY THE EVALUATION AND INCREASE THE ACCURACY. THE ELECTRONIC COUNTERS INSTALLED ARE CONNECTED SO THAT THEY ARE SWITCHED ON FROM THE BEGINNING TO THE END OF THE SERIES OF MEASUREMENTS. THE SPEED DURING THE MEASUREMENTS IS DETERMINED BY MEANS OF A QUOTIENT FORMER AND IS PRINTED OUT. THE QUOTIENT FORMER SHOULD ALSO BE CAPABLE OF FORMING THE AVERAGE OF THE COEFFICIENTS OF SLIP IN EACH SERIES OF MEASUREMENTS. FURTHER, THE MECHANICAL METERING SYSTEM HAS BEEN IMPROVED AND THE SUSPENSION OF THE DYNAMOMETER HAS BEEN MODIFIED. THESE STEPS LEAD TO A REDUCTION OF ERRORS AND TO THE EXCLUSION OF FACTORS WHICH HAVE SO FAR INFLUENCED THE RESULTS.
