鞋类市场面临的挑战是提高休闲鞋的舒适度，减震是舒适度最重要的特性之一。然而，可用于量化鞋类应用材料的减震性能的方法是有限的。通过这项工作，提出了橡胶材料减震性能的评估方法，并建立了不同测试方法之间的关系。制备了六种不同厚度的八种不同的商用紧跟橡胶材料，并根据其物理和冲击吸收性能进行了表征。根据实验值，定义了以下相关性：能量压缩/硬度和能量压缩/最大减速度。减震预测曲线也根据实验最大减速度值确定。结果为工业应用提供了一个出色的工具，因为它们可以将减震性能与鞋跟厚度相关联，并且还可以预测橡胶材料成分对最终产品减震性能的贡献。 (C) 2009 Elsevier Ltd. 保留所有权利。
A challenge that faces the footwear market is the improvement of casual shoe comfort, being shock absorption one of the most significant properties for comfort. However, the methodologies available for the quantification of the shock absorption properties in materials for footwear applications are limited. With this work, an evaluation methodology of the shock absorption properties of rubber materials is proposed and the relationship between different test methods is established. Eight different commercial compact heeled rubber materials at six different thicknesses were prepared and characterized according to their physical and impact absorption properties. From the experimental values, the following correlations were defined: energy compression/hardness and energy compression/maximum deceleration. Shock absorption prediction curves were also determined from the experimental maximum deceleration values. Results present an excellent tool for industrial applications since they allow correlation of shock absorption properties and heel thickness, and also to predict the contribution of rubber material composition to the final product shock absorption properties.
