Evaluation of roughness sensation using areal surface texture parameters based on geometrical product specifications under exposure to vibration

质感是为产品创造附加值所必需的。本研究以粗糙度来量化质地。本实验研究了感知量与粗糙度物理量之间的关系。用手触摸获得粗糙度的量。表面粗糙度采用ISO 25178-2：2012中定义的面状表面粗糙度参数值。实验结果，提出了设计表面粗糙度的目标值。此外，还提出了在有振动的动态条件下，通过改变起皱纹理表面的不同图案来改变表面粗糙度的方法。

The texture is necessary to create added value for products. This study was focused on roughness to quantify the texture. In this experiment, it was investigated for relation between amount of sense and physical quantity of roughness. The amount of roughness sensation was obtained with touching by hand. The values of areal surface texture parameters, which are defined in ISO 25178-2 : 2012, were used as quantity of roughness. Results of experiment, it was proposed targeted values including roughness sensation to design surfaces. Moreover, it was suggested to changing the roughness sensation by the difference pattern of wrinkled textured surfaces under the dynamic conditions with vibrations.
