Abstract

The embodiment of the invention discloses a method for measuring the elastic modulus of banknotes, which is used to solve the technical problem that the stretching method is not suitable for measuring the elastic modulus of old banknotes. The method of the embodiment of the present invention includes: measuring the deflection of the cantilever beam at both ends of the banknote; fitting the relationship formula between the elastic modulus and the bending deflection of the banknote through a data fitting method; substituting the deflection of the cantilever beam into the relationship as the bending deflection formula to calculate the elastic modulus of the banknote. The embodiment of the present invention also provides a device for measuring the maximum bending deflection of banknotes. The embodiments of the present invention can solve the technical problem that the stretching method is not suitable for measuring the elastic modulus of old banknotes.

Description

Technical field [0001] The invention relates to the technical field of material mechanical property testing, and in particular to a method for measuring the elastic modulus of banknotes and a device for maximum bending deflection. Background technique [0002] Banknotes with different levels of new and old have different stiffness, and elastic modulus is generally used to characterize the stiffness. Under constant load, the deformation posture of the banknote in the ATM transmission channel depends on the rigidity of the banknote itself. In the process of designing ATM banknote transmission channels, it is generally necessary to consider the adaptability of the transmission channel structure to banknotes of various stiffnesses. Therefore, it is very important to determine the elastic modulus of banknotes with different degrees of new and old. [0003] Generally speaking, the measurement of the elastic modulus of thin media should follow the tensile performance test method. The pri...
