利用有限元方法预测女鞋底曲挠度的可行性研究
|
摘要
鞋类的曲挠度是作为评价鞋子舒适度的一个重要指标,对于该指标的测试通常需要特定的测试仪以及专业操作员,这带来大量的产能和人力的消耗。有限元方法可以很好的预测物体的受力过程,同时该过程完全数字化,可以节约生产成本。因此,本研究的目的在于评估将有限元方法运用在曲挠度测试中的可行性。我们通过曲挠度测试机器测试了一款女式凉鞋,同时通过有限元模拟的方法测试出了该模型在虚拟环境中的曲挠度。最终物理结果显示曲挠度为7.8°,有限元模拟出的角度为3.9°。同时,我们发现在有限元方法中,鞋底内部的力的变化可以被模拟出来。最终结论显示出有限元方法作为模拟曲挠度测试过程预测曲挠度是可行的,并且该方法在制鞋行业的其它方面具有很大的潜能。
Flexibility of sole(FS) is one of the key parameter of comfortability and it is commonly required specific testing and certified operators. These processes increases the consumption of production capacity and human resources. Finite element method(FEM) is a low cost method which is able to predict the stress procedure. So, the aim of this study is to evaluate the feasibility of FEM on the FS test. The FS of a lady sandal shoe in real machine and simulated its FS ability in FEM have been tested. Final outcome showed that physical result was 7.8°, while that of FEM was 3.9°. Moreover, the force from every direction of inner parts of soles can be founded. In conclusion, FEM was feasible to simulate the flexure testing process to predict flexure angle and this method showed a great potential in shoe manufacture.
