英文要約Title:Construction of conceptual design methods using topology optimization for rapid and creative product development

In 2014, we developed fundamental topology optimization theories for the design of heat flux control devices and began our investigation of CAD-data generating software. As a first step in developing the methodology for topology optimization of heat flux control devices, we developed several topology optimization methods for the design of temperature field control devices, including a method in which target shapes are represented using the level-set method and updated based on the concept of the phase field theory. These methods can provide optimal material distributions that enable temperature field control, such as temperature uniformity control, heat focusing, and thermal cloaking. Next, we developed theories for multiscale topology optimization that can simultaneously optimize macro- and micro-structures considering thermal deformation. First, we constructed a multi-scale analysis model for plate and shell structures, to enable evaluation of macroscopic characteristics while considering microstructure characteristics, and then we formulated a multi-scale analysis method that can be applied in topology optimization of plate and shell structures considering thermal deformation. In addition, we investigated the marketing potential for optimal devices obtained through the topology optimization methods developed in this project. Our investigation suggests that newly developed devices may dramatically enhance the thermal performances of products such as printed circuit boards and inverter cases. In this project, an inverter case was selected as a design target, and simplified analysis models of inverter cases were developed to conduct feasibility studies of the development methods. We also carried out preliminary investigations and identified issues concerning the development of CAD-data generating software. We conducted a thorough survey of submitted papers pertaining to techniques for automatically discretizing closed triangle sets into second-order surfaces, and confirmed that variational techniques are very promising for accurate curve fitting, despite their computational cost.
