Verification for Constructing Digital Twin of POWDER TESTER

Abstract

The world is rapidly being digitized due to the advocacy of Industry 4.0 and the provision of IoT platforms in the industrial world. As a result, digitization has become a central topic in the manufacturing industry. Among the various aspects of digitization, digital twins have attracted considerable attention. However, implementing digital twins poses many technical challenges, demanding advanced calculations, especially in the field of powders, where the consideration of particle behavior is complex. In order to solve these problems, we have focused on measuring the angle of repose and bulk density using the “POWDER TESTER” as the standard method for numerically evaluating powder behavior in practical industries. This approach allows us to develop a simulation model forming the basis of the digital twin in the powder field, in collaboration with DENSE Co., Ltd. Although powder simulations are computationally expensive in general, we managed to perform this simulation within a practical timeframe by applying a coarse-grained model. In this report, we report the construction and verification results of this simulation model.
