Safety Regulation Compliant Software for Automobile Projection Check with 3D CAD Data

Plug-in for DFAS | DFX Analyzer

The Plug-in for DFAS (Design for Automotive Safety) detects geometries in 3D CAD data of automobiles that do not meet safety standards, enabling the realization of safe designs based on international regulations to prevent injuries towards occupants and pedestrians.

Automated Inspection Process in 3D to Prevent Rework

Automotive designers pay detailed attention to ensuring safe designs that do not harm individuals. One aspect of verification involves checking for protrusions in the CAD models they design.

In the current inspection process, designers often visually or manually inspect CAD models, leading to insufficient checks. Critical errors may only be noticed during the prototype confirmation phase before mass production.

The Plug-in for DFAS efficiently verifies 3D CAD data of automotive body parts on behalf of designers, enhancing design quality and reducing inspection process time.

Efficient Verification in a Short Time

In some innovative companies, unique digital verifications using CAD software functionalities are performed.

However, when verifying the entire CAD model, the computation time can be lengthy. Consequently, designers typically rely on their experience to intuitively narrow down verification areas, leading to potential issues discovered in later stages and resulting in rework.

Plug-in for DFAS identifies areas in the CAD model that require verification mathematically and theoretically based on shapes representing the head and knees, ensuring compliance with design standards to prevent harm to individuals.

Digital Projection Check Examples

Plug-in for DFAS contacts head forms and knee forms with the CAD model, calculating curvature radius at contact points.
Non-contact areas are excluded from the check process, allowing for efficient check.

Distance between two point contact areas of the head form
Curvature radius of the knee form contact area

Benefits of Implementation

Acceleration and Precision

The time-consuming task of checking projections in automobiles is expedited, providing high-speed checking.

Compared to traditional methods relying on human intuition, the Plug-in for DFAS offers high-precision checking.

Prevention of Losses Worth Millions

Discovering design flaws right before mass production, either through checks by third-party safety certification entities or internal processes, can lead to losses in the millions.

Resolving issues at the digital data stage before prototyping significantly reduces the risk of design errors, enhancing product safety.

Enabling Innovative Design

Designers, concerned with safety standards, may unconsciously limit creative design possibilities.

The Plug-in for DFAS conducts geometry checks based on safety standards, allowing designers the freedom to pursue innovative and aggressive designs with confidence.

Check Part Examples

Plug-in for DFAS checks various parts of both the interior and exterior of automobiles, supporting designs that protect both occupants and pedestrians.

Examples of Interior Parts

Instrumental Panel

  • Check to protect the upper body of occupants during collisions

Roof Panel

  • Check to ensure no injuries are incurred to occupants’ heads upon contact with the roof
Examples of Exterior Parts

Front Grill

  • Check to protect pedestrians during collisions

Door Surroundings

  • Check to prevent injuries to pedestrians in the event of side impacts

Flexible Customization

In addition to verification based on international standards, it is possible to incorporate company-specific criteria and expertise.

Building a unique internal and external projection check system allows for efficient manufacturing processes without compromising safety.

Applications Beyond Automobiles

Not limited to automobiles, every product requires designs that are considerate of human safety.

As long as the product is design using 3D CAD software, the technology of Plug-in for DFAS can be applied for digital protrusion verification.

Safety Regulations on Internal and External Projections

International automotive safety regulations have been applied towards many countries where automobiles are designed and manufactured. Through this trend, Plug-in for DFAS is mainly in compliance with the United Nations Economic Commission for Europe Regulation No. 21 (Uniform Provisions Concerning the Approval of Vehicles with Regards to their Interior Fittings) and United Nations Economic Commission for Europe Regulation No. 26 (Uniform Provisions Concerning the Approval of Vehicles with Regards to their External Projections).
