Abstract

The invention discloses a sole vibration transfer characteristic analysis method. The method comprises the following steps: S1, establishing a sole three-dimensional solid model; s2, establishing a finite element model of the sole model in the step S1, and performing modal analysis to obtain natural vibration characteristics of the finite element model; s3, based on the finite element modal analysis in the step S2, performing steady-state kinetic analysis on the shoe sole to obtain response conditions of the shoe sole to vibration under the three working conditions; s4, calculating and drawing a shoe sole equivalent mechanical admittance distribution cloud picture by utilizing a Python programming language, and obtaining the distribution condition of the equivalent mechanical admittance of different areas of the shoe sole; and S5, based on the distribution condition of the equivalent mechanical admittance of the different areas of the shoe sole, calculating and obtaining the distribution condition of the equivalent vibration transmissibility of the different areas of the shoe sole by utilizing a Python programming language. According to the method, the response condition of the sole to the vibration and the transmission condition of the vibration in different areas of the sole can be obtained by utilizing a finite element analysis method.

Description

technical field [0001] The invention relates to the field of vibration analysis, in particular to a method for analyzing the vibration transmission characteristics of shoe soles. Background technique [0002] Numerous studies have shown that long-term exposure of human feet to vibration can put them at an increased risk of developing vibration-induced white feet. When the foot is in contact with vibration, the sole is the part that is most directly in contact with the impact vibration from the ground, and it also plays the role of vibration reduction and vibration isolation. The research on foot and sole vibration mainly adopts the method of kinematics measurement, which has many disadvantages, such as long test period and high cost. Contents of the invention [0003] The main purpose of the present invention is to overcome the above-mentioned defective in the prior art, propose a kind of sole vibration transmission characteristic analysis method, by means of the method f...
