How to be Ready for the Future with THOR and WorldSID

Across the world, New Car Assessment Programs (NCAPs) are shifting to more accurate tests. These tests use more lifelike dummies and represent a wider range of people.

In the United States, there is growing focus on advanced ATDs. The USA is moving to adopt THOR ATDs. These include the 5th percentile female crash test dummy (THOR-5F) and 50th percentile male dummy (THOR-50M).

This is not an incremental update. It marks a step-change in how we define and measure safety.  

Humanetics’ THOR and WorldSID ATDs represent the next generation of safety measurement systems.

They meet regulatory requirements by design. They also help us better understand how people respond in crashes. That allows for softer vehicle design.

THOR delivers:

• Advanced instrumentation across the head, neck, thorax, and lower extremities
• Improved biofidelity, particularly in frontal impact scenarios
• Enhanced ability to capture injury mechanisms rather than simple thresholds

WorldSID provides:

• High-fidelity side-impact measurement
• Advanced rib cage and thoracic response capabilities
• Global harmonization for side-impact testing protocols

THOR and WorldSID are comprehensive platforms for evaluating safety performance across multiple crash modes.

Advanced ATDs like these are used by top automotive OEMs, ship builders, locomotive designers, and in aeronautics.

These are some of the ways THOR and WorldSID make you ready for future changes.

Regulatory and consumer safety programs are speeding up the evolution of ATDs.

NCAP organizations worldwide are increasingly recognizing the need for more representative and biofidelic testing tools. In the United States and Europe, this is clear in the focus on THOR-5F female crash test dummy. This reflects a broader commitment to improve safety for more people.

This shift signals two important trends:

1. Safety is becoming more inclusive. Testing is moving beyond a single reference occupant toward a more representative view of real-world populations.
2. Measurement expectations are increasing. Regulators are demanding more detailed and more accurate data to support safety ratings and compliance.

For manufacturers, this means that adopting advanced ATDs is the safe long-term bet. Advanced ATDs are moving towards becoming a requirement for staying aligned with future standards. 

In a traditional setup, engineers may use a small set of injury criteria. They focus on key metrics like head acceleration or chest deflection.

THOR makes the picture more complete.

Engineers can access detailed measurements across many body regions, including thoracic response, neck dynamics, and leg loading. This enables a more nuanced understanding of how injuries occur and how systems interact with the occupant. 

WorldSID provides similar advancements, capturing rib deformation and thoracic response with greater accuracy and consistency.

The result is not just more data, but more meaningful data.

Data that allows engineers to move from evaluating outcomes to understanding causes.

The evolution of THOR and WorldSID does not stop at the physical device.

A key advantage of Humanetics’ approach is a digital twin ecosystem, where physical ATDs match high-fidelity virtual models.

These digital ATDs are:

• Built directly from the physical design and behavior of THOR and WorldSID
• Validated against real-world test data
• Designed to replicate sensor outputs and injury criteria in simulation

This makes them among the most faithful virtual representations available.

The benefit is significant.

Engineers can run simulation scenarios using digital THOR and WorldSID models that behave consistently with their physical counterparts. This enables:

• Early-stage design evaluation with high confidence
• Reduced reliance on late-stage physical testing
• Strong correlation between virtual and physical results 

What truly sets Humanetics apart is not only the quality of its ATDs, physical or digital. It is also the system that connects them.

Through a digital data loop, information flows continuously between:

• Physical crash testing
• Sensor data and instrumentation
• Simulation models and digital twins
• Analysis and validation tools

Physical tests inform digital models. Digital simulations guide physical testing.

Teams share, refine, and reuse data sources across the entire development process.

This closed-loop approach grounds every insight in reality and continuously improves every model. It transforms testing from a series of isolated events into a continuous process of learning.
