RAMSIS: The Digital Human Model for Ergonomics in Vehicle Design

In today’s automotive landscape, designing a vehicle is no longer just about performance or aesthetics—it’s about people. As comfort, safety, and inclusivity become essential components of vehicle design, integrating human-centric approaches right from the conceptual phase is no longer optional.

This is where RAMSIS makes all the difference.

What is RAMSIS?

RAMSIS (Realistic Anthropometric Mathematical System for Interior Comfort Simulation) is the world’s leading digital human modelling (DHM) software, developed by Humanetics Digital Europe GmbH (former know as Human Solutions). It enables engineers and designers to simulate human interaction with vehicle interiors early in the design cycle using virtual manikins derived from real-world human body data.

From driver workspace design to posture validation and reach analysis, RAMSIS ensures that products are ergonomically optimized, safe, and ready to meet international regulations before any physical prototype is built.

Why Ergonomics Matters in Vehicle Design

Every interaction—be it steering, entering and exiting, adjusting a seat, or reaching a control—affects user comfort and safety. Poor ergonomics can lead to fatigue, discomfort, or even safety hazards.

With RAMSIS, vehicle manufacturers can account for variations in body size, gender, age, and regional population characteristics, ensuring the design suits real human needs. This is especially important today, as vehicles become more diverse in form—electric, autonomous, off-road, or specialized.

Key Capabilities of RAMSIS

• Vision analysis
• Reach and accessibility validation
• Ingress/egress simulation
• Posture and seat comfort evaluation
• Customizable avatars with country-specific anthropometric data

Seamless Integration and Flexibility

RAMSIS supports effortless integration with major
design platforms, including:

• CATIA V5
• 3DEXPERIENCE Platform
• SIEMENS NX

It is also available as a standalone application,
providing flexibility for teams using varied design tools.

Broad Industry Applications

While RAMSIS is widely used in the development of passenger vehicles, commercial vehicles, defence, and aircraft, it has also gained significant traction among two-wheeler and three-wheeler OEMs. As these industries begin prioritizing ergonomic standards, RAMSIS offers a reliable way to evaluate rider posture, seat height, and control accessibility even at early stages.

The Advantage: RAMSIS’s Core Strengths Over Its Competitors

1. Anthropometric Database
   One of RAMSIS’s most powerful differentiators is its extensive and validated anthropometric database.

Anthropometry is the scientific study of human body dimensions—such as height, limb length, joint angles, and sitting postures. It plays a vital role in ensuring that product designs are tailored to the target user population.

RAMSIS includes region-specific anthropometric data for nearly every major geography—except Africa—and supports multiple population groups, age ranges, and genders.

In India, RAMSIS incorporates the ARAI Size India Database, which is valid until 2040. This allows OEMs to design vehicles for future Indian populations. For instance, if you’re designing a car to launch in 2030, RAMSIS enables you to simulate what the average male and female body proportions will look like by then—ensuring future compliance and customer comfort.

2. Scientifically Developed Posture Models
   Another major advantage of RAMSIS lies in its realistic posture models—carefully developed to reflect actual human body behaviour in different scenarios.

Posture models in RAMSIS are standardized, ergonomically optimized representations of how humans sit, stand, reach, or drive in real-world conditions. These aren’t arbitrary or algorithmically guessed poses—they’re the result of detailed empirical research.

Humanetics Digital Europe GmbH (formerly known as Human Solutions) developed these posture models by conducting live physical studies. For every posture model—be it for a driver, passenger, or operator—more than 40 real participants were observed sitting or standing in the target position for up to 3 hours. Each participant was analysed for posture consistency, comfort, and biomechanical alignment, and the results were fed into RAMSIS’s model framework.

This hands-on, data-driven process ensures that RAMSIS posture models are scientifically validated and ergonomically optimized, offering unmatched realism compared to other DHM tools.

What’s New in RAMSIS NextGen

The latest version of RAMSIS—NextGen—features a refreshed interface, improved simulation accuracy, and greater flexibility for creating manikins. It supports more detailed analysis scenarios for both traditional and next-generation mobility solutions.

Conclusion

RAMSIS bridges the gap between digital design and real human experience. With its unmatched anthropometric database, scientifically validated posture models, powerful simulation capabilities, and seamless CAD integration, it enables OEMs to develop vehicles that are ergonomically sound, regulation-compliant, and ready for the future.
