Method for determining the dynamic characteristics of a ski boot

摘要

The present invention refers to a method for determining the dynamic characteristics of a ski boot comprising the steps of selecting at least three parameters suitable to represent some dynamic characteristics of the boot, experimentally determining the values assumed from each of the parameters, and finally determining the dynamic behavior of the ski boot on the basis of the combination of the values measured in the previous step. Also claimed is an apparatus for determining a parameter of dynamic behavior of a ski boot.

1. A method for determining the dynamic characteristics of a ski boot comprising an upper shell and a lower shell, comprising:
a) defining at least a first, second and third parameter, (S), (P) (R) which represent dynamic characteristics of a ski boot; b) experimentally determining the value of said first parameter for said ski boot; c) experimentally determining the value of said second parameter for said ski boot; d) experimentally determining the value of said third parameter for said ski boot; e) defining a dynamic behaviour of said ski boot based on a combination of the values measured in said steps b) to d), wherein: said first parameter (S) is a bending moment, measured in Nm/°, to be applied to bend an upper shell of the ski boot to a first angle α relative to said lower shell starting from a neutral position; said second parameter (P) adimensionally expresses a stiffness increase during the bending from a neutral position to a maximum bending position of the upper shell relative to a lower shell; and said third parameter (R) expresses a speed to which the upper shell returns to the neutral position from a maximum bending position relative to the lower shell.
