Multi-cell structure sole vibration energy transfer evaluation method

Abstract

The invention discloses a vibration energy transfer evaluation method for a multi-cell structure sole. The method comprises the following steps: S1, establishing an original sole three-dimensional entity model; s2, constructing multi-cell structures of different lattice types, and respectively filling the multi-cell structures into the heel areas of the soles to obtain multi-cell structure soles of different lattice types; s3, constructing a finite element model of the multi-cell structure shoe sole in the step S2; s4, performing steady-state dynamic analysis on the multi-cell structure sole to obtain a response condition of the multi-cell structure sole to vibration; s5, calculating and drawing an equivalent mechanical admittance distribution cloud picture of the multi-cell structure shoe sole by utilizing a Python programming language, and collecting the distribution condition of the equivalent mechanical admittance of different areas of the multi-cell structure shoe sole; and step S6, based on the distribution condition of the equivalent mechanical admittance of the different areas of the multi-cell structure sole, calculating and collecting the distribution condition of the equivalent vibration transmissibility of the different areas of the multi-cell structure sole by using a Python programming language.

Description

technical field [0001] The invention relates to the field of vibration analysis, in particular to a method for evaluating vibration energy transfer of multicellular structure shoe soles. Background technique [0002] The multicellular structure is used in the design of the cushioning structure of the sole because of its excellent cushioning and energy-absorbing effect. Studies have shown that the presence of a multicellular structure can reduce the impact of the foot from the ground and play a role in cushioning and absorbing energy. However, the research on the vibration of the multicellular structure sole is rarely involved. In addition, the current research on foot and sole vibration mainly adopts kinematics measurement method, which has many shortcomings, 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 defects in the prior art, propose a kind of multicellular struc...
