Denso Techno reduces vehicle noise analysis time by 5X on Oracle Cloud

Automotive parts manufacturer cuts complex fluid noise analysis and simulation times with high-performance computing on Oracle Cloud Infrastructure.


Now that we have various technical support from Oracle, including networking, we can prepare a cloud environment in a short period of time. We look forward to strong support from Oracle, including providing the latest advanced technologies in the future.

Business challenges

Denso Techno is part of the Denso group, one of the world’s largest manufacturers of automotive parts. The company reviews specifications and supports mass production, development, and design for its customers. In addition, its technical team provides software design, electronic circuit design, and equipment design.

With the rapidly growing market for electric vehicles, the demand for noise minimization has become one of the auto industry’s primary focus points. Because many vehicles now have very little noise in their drive systems, Denso Techno’s attention has shifted to internal cabin components via fluid noise analysis, a key technology for efficient design that suppresses noise generation.

Denso Techno has been running noise analysis calculations using high-performance computing (HPC) to meet market demands. Traditionally, the company’s HPC systems had operated in an on-premises environment. However, its legacy system created numerous challenges, including the lengthy time needed to run tests. Complex calculations could take more than 15 days, making it very difficult for the company to conduct frequent analyses.

Why Denso Techno Chose Oracle

After benchmarking multiple cloud service providers, Denso Techno confirmed that the speed of high-performance computing on Oracle Cloud Infrastructure (OCI) could readily clear its target calculation times. Ultimately, the company decided to implement OCI into its design workflows.


What Denso Techno noticed first was that price-performance immediately improved on Oracle Cloud Infrastructure versus its old on-premises environment. The license system running Denso Techno’s vehicle noise application was far slower, creating longer calculation times, and thus much higher costs.

With HPC on OCI, calculations now run 5X faster than the previous solution, reducing calculation time from 15 days to 3 days, and cutting costs by nearly 50%.

Keiji Koumura, director of Denso Techno’s Computer-Aided Engineering Department, says the company will use Oracle Cloud HPC to establish basic technology for noise analysis and further improve the level of simulation utility in its designs.

“If we can improve the accuracy and reliability of the simulation and reach a level that the designer is satisfied with, we can propose better designs and make suggestions with confidence,” says Koumura. If simulation-based manufacturing evolves in this way, lead time should naturally be shortened.
