Efforts toward DX on Manufacturing Sites with Digital Work Instruction System Realizing data sharing on manufacturing sites

  • IHI Corporation

It is unexpectedly difficult to realize digital transformation (DX) at manufacturing sites. It takes a lot of labor to arrange the necessary equipment and digital information. This time, we worked on the realization of DX at our manufacturing site with the slogan “Let’s begin with what we can do.” This article introduces the activities and results of the efforts using a digital work instruction system and data that we have digitalized on our own.

Analytical Evaluation of Structural Performance for Reinforced Concrete Road Bridge Decks Considering Cracks in Concrete

  • YOSHIDA Yuki, TAKESHIMA Natsumi, NIE Jing, KISAKU Tomoaki, OKADA Seiji

There are many deteriorated reinforced concrete road bridge decks (RC slabs) in Japan. Limited maintenance and renewal budgets create a need for the technologies to prioritize repair and replacement of in-service RC slabs. Techniques to evaluate the structural performance of in-service RC slabs, such as load carrying capacity and failure process, are potential prioritization criteria. Nonlinear analysis is used in evaluating the structural performance of RC slabs because of its capability for appropriately considering the influence of cracks existing in concrete. Therefore, the accuracy of nonlinear analysis was verified by reproducing various loading tests of the RC slab specimen. The results indicate that nonlinear analysis is effective as a criterion technique for determining repair and replacement priorities.

  • HAYASHI Katsunori, KANEDA Shinichi, IKEYA Nobuyuki, DAITO Yuichi, KITAMURA Kazuhiro

Fuel cell systems such as the fuel cell vehicle (FCV) are being used more and more toward the realization of carbon neutrality. IHI is developing a new electric turbocharger (ETC) that has high efficiency to meet the requirements in regards to performance, cost, and reliability of various fuel cell systems. In addition to meeting the needs from the improvement in efficiency of the systems, we are also working to improve manufacturability with a view to future mass production. This paper introduces the strengths of IHI’s newly developed ETC-M, the benefits that the ETC-M brings to fuel cell systems, and the elemental technologies that support them.

On Advanced Turbocharger Technology and Development


Recent political announcements, especially in the European Union, imply that passenger car propulsion technology based on Internal Combustion Engines (ICE) is outdated and will not be further developed. Nevertheless, next to battery electric propulsion turbocharging and turbocharged ICE are seen as a technology path that can and will support transformation into a society that does not depend on fossil fuels. Related expertise and development capabilities will contribute to further enhancing propulsion systems with highly efficient turbochargers (TCs) that combine lifetime durability with best quality, but also best cost. The paper at hand provides an overview of advanced TC technologies and their specifics serving modern propulsion systems. It showcases development expertise that is relevant for many carbon-free technology areas.

Evaluation of Interface Strength Properties in Vicinity of Fiber-Matrix Interface in Ceramic Matrix Composites

  • KANAZAWA Shingo, KISHI Tomonori, KUBUSHIRO Keiji

The strength properties of ceramic matrix composites (CMCs), which have been expected to be applied to high-temperature section parts of aircraft engines, are greatly affected by the fiber-matrix interface strength properties. However, there are few reports on the interface strength properties of small diameter fibers used in CMCs. In this paper, we investigated the appropriate device, indenter shape and thickness of the test specimen for the push-out test, one of interface strength property tests, to establish an interface strength property evaluation method applicable to CMCs consisting of small diameter fibers approximately 10 mm. As a result of the test, it was found that the interface strength properties of CMCs with a thickness of 116 mm or less can be evaluated by using a nano-indenter with a round end cone shape indenter. However, the push-out test is not enough to be a quantitative test method so far in that the plumbness of fibers to specimen thickness cannot be considered.
