Specially appointed lecturer
Nobuyuki Umetani
Introducing research on real-time simulation technology useful for interactive design and speeding up CFD simulation using machine learning.
From the idea of enlivening the world’s manufacturing with software that can be easily designed, we can detect structural vulnerabilities in real time just by giving ideas and shapes for speeding up simulations that make 2D fashion design 3D in real time. The idea of cross-sectional structure analysis for the system to be used, the idea of performing acoustic analysis in real time using the boundary element method for the system of making musical instruments with a computer, and the flight prediction machine for the system of optimizing the design of paper airplanes with a computer. For ideas using learning and systems for predicting the air flow around a car, we will introduce ideas for predicting Cd values in real time by machine learning.

「Transition and future prospects of digital development at Mitsubishi Motors」
Mitsubishi Motors Corporation
Chief Technology Engineer, Vehicle Technology Development Headquarters
General Manager of Technology Planning Department
Mr. Hirotaka Shiozaki
It has been 103 years since Japan’s first mass-produced passenger 「Mitsubishi Model A」was developed and released in 1917.
Nowadays, it is said to be the “era of revolution once in 100 years”, and it will be the first era of revolution after the launch of mass-produced passenger cars.
In the meantime, before the 90’s, MMC was trying to make better products by seeing the “essence of the phenomenon”.
Furthermore, since 2000, advances in digital technology have led to improvements in product appeal and short-term development.
On the other hand, I think it is an era when the attitude of seeing the “essence of the phenomenon” has diminished.
In the era of the first major transformation, further reform of digital technology is required, and Mitsubishi Motors believes that it is important to make full use of digital technology and to re-examine the “essence of the phenomenon”.
For that purpose, we proposed the need for new digital technologies such as integration of database, CAD, CAE, and CAT, and utilization of Knowledge.

「Efficient exhaust pipe model creation」
Toyota Motor Corporation
CV Vehicle Performance Development Department Reliability Development Office
Chief
Mr. Shigeo Maeda
In the conventional vehicle development process, CAE man-hours are enormously required, and modeling man-hours account for more than 50% of the total. Specifically, it took time to model each welded part and bent pipe, which are evaluation parts, and a muffler without CAD. Therefore, with Jupiter-Pre, we have developed special functions for exhaust pipes such as pipe remesh and welding.
By switching from the conventional software to new one for real problems, the modeling man-hours and total man-hours could be reduced by 70%.

「Consideration of piston striking sound due to piston behavior and skirt rigidity」
3rd Technology Development Office – Group 0
Researcher
Mr. Toshiaki Kobayashi
Various efforts are being made to meet the demand for improved fuel efficiency of automobiles, and reciprocating engines are being further improved. Pistons, which are fundamentally related to performance, are required to ensure and embody durability and quietness as well as improve fuel efficiency. Combustion and weight reduction that require high efficiency are in conflict with them, and it is important to design a shape that balances them at a higher order. In this paper, we consider the relationship between rigidity and quietness and frictional resistance from the piston behavior, and explore the ideal form of rigidity in piston design.

「Changes in structural analysis systems at Yamaha Motor and collaboration with TechnoStar」
Yamaha Motor Co., Ltd.
MBSE Promotion Department, Digital Development Section, Mobility Technology Headquarters
MBSE Construction Group Chief
Masataka Kondo
Yamaha Motor’s structural analysis system has been provided a designer’s tool on the same CAD platform. From the perspective of the manufacturer, we look back on the transition of Yamaha Motor’s structural analysis system and collaboration with TechnoStar. Yamaha Motor Co., Ltd. has been involved with TechnoStar from VENUS-Pre and Post and now Jupiter. During that time, we have continued joint development with TechnoStar and is developing various solutions. In the future, we will work on redefining the designer CAE and improving engineering capabilities by issues, and will continue to collaborate with TechnoStar as its partner.

「Example of Jupiter utilization in Honda motorcycle engine development」
Honda Motor Industry Joint Stock Company
Motorcycle Business Headquarters Manufacturing Center
Power Unit Development Department Power Design Section
Mr. Toru Sakai
The Motorcycle Business Headquarters uses DPM (defined as a prototype vehicle on a computer that aggregates 3D data) to carry out the evaluation / verification using CAE for many specification studies at the initial stage of design, which is effective in shortening development costs and development period. In order to satisfy the required performance within the limited development lead time, it is necessary to output the analysis results at a speed that exceeds the design L / O examination.
Therefore, in engine development, we started switching from TSV to Jupiter in 2017, and now we are operating it as a core Pre-Post. By making repeated improvements from the beginning of switching, operability and overall performance have improved. Furthermore, by using the optional Oasis Mesher (automatic mesher) and automatic replacement function, the model creation speed for nonlinear CAE has been increased from 3 times to 5 times faster than before.

「Introduction of fatigue strength analysis method considering detailed temperature distribution」
Honda Motor Industry Joint Stock Company
Motorcycle Business Headquarters Manufacturing Center
Power Unit Development Department Power Design Section
Hideshi Iimura
Lightness and design are emphasized in the exhaust system parts of motorcycles, and various metal materials are used. On the other hand, due to the recent tightening of environmental regulations, exhaust gas tends to have a high temperature, and it is necessary to select a material having appropriate strength. Against this background, an analysis method with high prediction accuracy and execution in a short time has been desired.
Therefore, in order to improve the accuracy of high-temperature strength analysis, we have established a method of mapping different material properties for each temperature with Jupiter and collectively performing fatigue treatment using multiple fatigue limit diagrams. In addition, in order to speed up modeling and to standardize operations, the exhaust system modeling function of Jupiter was utilized to reduce the modeling time to about 1/4 of the conventional one.
Key features
★Jupiter-Pre ＞ Exhaust system modeling
★Jupiter-Post ＞ Material mapping, multiple fatigue limit diagrams, fatigue evaluation
★SunShine ＞ Heat transfer analysis, thermal stress analysis, temperature-dependent eigenvalue analysis, stress recovery

In recent years, acoustic analysis inside and outside the vehicle has become extremely important in advancing vehicle development.
Creating an acoustic analysis model requires a lot of works and time-consuming.
We analyzed the model creation process and operation time, Jupiter has reduced the man-hours by 70%.
We will also improve efficiency for more detailed models.

「Transmission Casing Strength Analysis (Designer CAE) Automation Initiatives」
Aisin AW Co., Ltd.
Technology Headquarters Analysis Technology Department – 2nd Group
Group manager
Mr. Go Suzuki
Transmission casings are required to be compact and lightweight while ensuring sufficient strength for the market. Therefore, it is indispensable to carry out strength examination by CAE, but due to the complexity of the analysis model, the modeling man-hours have become a heavy burden on the designer. Therefore, in order to reduce the development man-hours, we started full automation of casing strength analysis using Jupiter-Oasis.
By combining the automatic update and copy function of load conditions, Oasis Mesher (fully automatic mesher), SunShine solver, automatic report, etc., the casing strength analysis generated by the replacement of newly designed parts has been fully automated. In particular, by repeatedly improving the fillinget meshing technology, we were able to bring the fully automatically output results to the same level as the meshing results created by a dedicated person.
