What strategic measures and solutions have companies in the aerospace, defense, and automotive manufacturing industries adopted in the application of MBD technology?

3D models are replacing 2D drawings, becoming the universal language of high-end manufacturing. This transformation from drawings to data has been fully launched in aerospace, defense, and automotive manufacturing sectors.

2025 Year 2 Month, Hongyu Precision Group's Digital Intelligence Development Department announced the official launch of the country's first fully autonomous and controllable MBD product design technology platform. After nine months of intensive effort, the project successfully built an intelligent design solution covering tool interfaces, methodology systems, and data ecosystems, marking the official entry of enterprise digital mockup construction into the digital definition era.

In the aerospace field, digital assembly process design based on MBD has become mainstream. Taking aircraft assembly as an example, process designers directly carry out 3D process design based on 3D solid models, changing the previous practice of relying on both 2D engineering drawings and 3D solid models.

By establishing a digital assembly process flow, enterprises can perform virtual assembly verification of manufacturing processes before physical assembly, and only after confirmation will the assembly process authorization be issued for use.

👀 01 Aerospace Field: Model Revolution Throughout the Entire Lifecycle

China Aerospace Science and Technology Corporation has clearly made "a unified product model system throughout the entire lifecycle of model products" the first overarching strategy for digital transformation in aerospace research and production. The group is transforming the traditional development model into a new model based on model data: "digital design - digital manufacturing - digital testing - digital delivery."

The "Three Space Stations" system built by Beijing Satellite Manufacturing Plant — covering digital space station, on-orbit space station, and ground electrical space station — achieves four major features: seamless information transfer, efficient collaborative development, comprehensive closed-loop verification, and digital operation support. Its model system not only includes traditional 3D structural models but also extends to requirement models, functional models, process models, manufacturing models, and other full domains.

AVIC Chengfei successfully overcame Boeing 787-9 large part MBD measurement challenges. The project’s beams and skins are 10 meter large composite parts with extremely high hole position accuracy requirements. 2025 At the beginning of the year, in response to Boeing FAA new requirements for measurement under digital model definition benchmarks and natural state of sandbag compression, Chengfei's technical team, after two months of effort, MBD successfully passed the 3 month FAA audit and received high praise from Boeing.

👀 02 Defense and Military Industry: 3D Models Break Down Design and Manufacturing Barriers

The Eighth Academy of Aerospace 805 and 149 factory collaboration represents a typical path of military industry MBD application. Both parties, based on MBD key technologies, achieved cross-platform transmission of full 3D design data, with the factory directly conducting process design and production manufacturing based on 3D models.

This project successfully eliminated 2D drawings, realizing full 3D model-controlled factory delivery as the sole basis for parts production and final assembly. By developing a signature and approval tool based on Pro/E a full 3D model electronic approval process was established, along with system separation of three roles, security policies and log auditing, data classification control, and other security upgrades.

China Aero Engine Corporation is also actively promoting MBD technology implementation. 2025 Year 1 In month, China Aero Engine Xi'an Power Control Technology Co., Ltd. completed the bidding for the "Research Project on Automatic Modeling Technology of Aviation Engine Fuel Control System Housing Parts Based on MBD Beihang University won the bid with 178 ten thousand yuan and will carry out a technical breakthrough for 420 days.

👀 03 Automotive Manufacturing: MBD Toolchain Drives Development Efficiency Leap

In the new energy vehicle field, control system development based on MBD has become the key path for domestic car brands to achieve technological breakthroughs. At the 3rd Intelligent Manufacturing Summit Forum, Shiguan Technology showcased a domestic MBD solution based on model design methods, featuring strong requirement traceability, high readability, and excellent software code quality.

This solution achieves full-link integrated innovation through the integrated modeling toolchain of GCKontrol 、 GCAir 、 TestManager shortening the development cycle and ensuring 30% independent intellectual property rights, effectively avoiding risks of technology supply interruption. 100% Month, Shiguan Technology further demonstrated the application of the

2025 Year 6 system simulation test verification integrated platform in joint simulation of vehicle dynamics and control systems at the 17th International Automotive Powertrain Technology Conference ( TMC2025 ) GCAir Its effectiveness in improving simulation speed and shortening product development cycles has been recognized by the industry.

Automotive parts giant JTEKT JTEKT achieved significant breakthroughs in bearing design through process upgrades. The company's newly developed main design system reduces design discussion time to one-quarter of traditional methods, greatly reducing designer errors. MBD JTEKT also innovatively developed an evaluation tester with built-in magnetic suspension bearings, capable of simulating ultra-high-speed rotation conditions up to

000 min-1 45， ( dmn value ten thousand) to meet the high-speed rotation requirements of electric vehicle electric drive systems. 270万）的超高速旋转条件，满足电动汽车电驱动系统e-Axle的高速旋转要求。

👀  04  Industry Trends: From Model Definition to Enterprise Transformation

Currently, the common transformation demands proposed by multiple aerospace institutes point to the construction of model-based enterprises ( MBE ). Experts from the Shenyang Engine Research Institute of China Aero Engine Corporation clearly state that full lifecycle modeling is one of the three major directions of digital engineering, and modeling capability is the core ability to build, apply, and manage models.

The Information Technology Center of AVIC emphasizes that cloud-based model-driven R&D environments are a new track for industrial software. By building N Unified — unified project management, unified requirements management, unified BOM management, unified development platform, unified software toolchain, etc., to achieve informatization of shared capabilities / Digital capability sharing center.

JettaGet's new design backbone system reduces design discussion time to one quarter of traditional methods, and Shiguan Technology's domestic MBD toolchain shortens the development cycle of new energy vehicle control systems 30% ; behind these numbers is a comprehensive restructuring of efficiency in high-end manufacturing.

As institutions like Beihang University continue to tackle the MBD automatic modeling technology for aerospace engine fuel control system housing parts, and more enterprises join the new cloud-based model-driven R&D track, 3D model definition technology is moving from single-point applications to full-chain integration.

This digital transformation led by MBD ultimately points to the comprehensive rise of model-based enterprises.
