STANDARDISATION OF WAGONS. SPECIFIC SPRING DEFLECTION OF LEAF SPRINGS

The report deals with the mean specific spring deflection C(a), value used for characterising leaf springs and it also contains indications for the determination and practical measurement of this magnitude. A uniform calculation procedure to determine this magnitude, deduced empirically from existing calculation formulae is valid for most of the springs with linear characteristics, as shown during the verification of springs made for this purpose. Furthermore, a relation is revealed between the mean specific spring deflection and the overall spring deflection in the double link suspension and for both numerical value pertaining to the usual spring designs are indicated. The indications concerning springs used in operation may furnish a basis for further investigations.
