Development of HMD-type attention attracting system using image recognition technology
Get PDFThis study describes a development of attention attracting system using a head mounted display (HMD), and the potential is indicated based on essential experiments. In these days, augmented reality (AR) and virtual reality (VR) technologies are applied to a variety of fields, such as education, industry, medical science, and so on. Moreover, image recognition technology has been widely used with the rapid development of machine learning. However, the practical knowledge has been scarcely accumulated so far. In this study, we could reveal the high potential of attention attracting system during workpiece setting on a machining center.departmental bulletin pape

An Analytical Solution of Axisymmetric Contact Problem of Elastic Layer-substrate Body
Get PDFWe consider an elastic contact problem for indentation test of layer-substrate body. An elastic layer assumed to be perfectly bonded to an elastic semi-infinite substrate. This problem called Boussinesq's problem which is axisymmetric mixed boundary value problem in elasticity theory. The elastic layer is smoothly indented by a flat-ended cylindrical and spherical indenter. This paper presents not only distribution of the dimensionless normal contact stress under cylindrical and spherical indenters but also distribution of the dimensionless normal displacement at the upper surface of the elastic layer. Numerical results are given for several combinations of the ratio of shear modulus, Poisson's ratio of elastic layer and substrate and the thickness of elastic layer. These results may establish the foundation for indentation test of layer-substrate composite and provide guideline for design of mechanical property of layered materials.departmental bulletin pape
