Embodiment Construction

[0047] The present invention will be further described below through specific embodiments.

[0048] A kind of sole model design method of heel region cushioning structure, such as figure 1 and figure 2 shown, including:

[0049] Step S1: Establish the sole model before optimization in UG.

[0050] Step S2: Establish the finite element model of the sole model in step S1 and perform static analysis, such as image 3 shown, including:

[0051] Step S21: Import the sole model and bottom surface model into abaqus. Abaqus is a set of powerful finite element software for engineering simulation, including a rich cell library that can simulate arbitrary geometric shapes, and has various types of material model libraries, which can simulate the performance of typical engineering materials.

[0052] Step S22: Assign material properties to the sole model and the ground model respectively, wherein the material properties include mass density, Young's modulus and Poisson's ratio, so ...

Abstract

The invention discloses a method for designing a sole model of a sole heel area buffer structure. The method comprises the following steps: S1, establishing a sole model before optimization; S2, establishing a finite element model of the sole model in the step S1, and carrying out static analysis; and S3, selecting an area in the heel area of the sole as an optimization area of the sole buffer structure, respectively establishing four different porous structure models in the area of the heel, and obtaining four heel area buffer porous structure models, namely M1, M2, M3 and M4; S4, setting boundary conditions for the four types of shoe sole structures, carrying out power flow visual programming in a phython language, and correspondingly carrying out dynamic analysis to obtain power flow visual cloud charts of the four types of shoe sole structures; and S5, comparing the power flow clouds of the four models, and selecting one optimal model as an optimal heel area buffer structure. The optimization design method can ensure that the buffer performance of the shoe sole is improved in the movement process.

Description

technical field [0001] The invention relates to the field of optimized design, in particular to a design method for a sole model of a cushioning structure in the heel area of ​​a shoe. Background technique [0002] With the rapid development of the footwear industry at present, the cushioning structure of the sole plays a vital role in sports, and its main purpose is to reduce the impact to reduce the damage of the foot. For the evaluation of the shock absorption performance of shoe soles, in addition to subjective evaluation, the most commonly used method is kinematics measurement, such as comparing the shock absorption effects of different shoe soles by measuring the pressure distribution of the soles and soles during exercise. [0003] The traditional method needs to make real objects first, and then let the testers put them on for testing and comparison. This method of evaluating the shock absorption performance of soles requires a large number of real objects for experi...
