Internship: Human Modelling - Signal Processing and Analysis

January-July 2023

The Hague, Netherlands

Simcenter Madymo is the industry leading software for analyzing human safety. The Madymo Active Human Model (AHM) has been developed to simulate the behaviour of vehicle occupants during manoeuvring, and it is an important development in ensuring the safety of occupants, especially in autonomous vehicles.

The Simcenter Active Human model is a kinematic simulation model of a human, designed in such a way that it actively attempts to maintain its posture when external loads are applied. This is useful for predicting posture, safety, and comfort in a range of situations, such as severe manoeuvring in a vehicle attempting to avoid or minimize a crash. This behaviour has been validated extensively against experimental measurements of human volunteer subjects.

However, while safety engineers would like to deal with simple, predictive responses, human behaviour is far less predictable and dependent on far more variables than can be meaningfully included in a repeatable numerical simulation, with extensive spread seen in most data. There is currently little consensus on the variability, and only a few researchers have attempted to quantify the statistical variation.

By analysing and understanding the signals and their variability in greater depth, we can provide more predictive models and more sound advice to safety engineers. Principal component analysis can simplify complex data fields, which can then be statistically treated to understand the significance and relevance of the data.

This internship will be run with the SaCoMo (Safety and Comfort Modelling) group based in The Hague, Netherlands.

Scope 

The aims of this internship are to review the current female and size-scalable active human models, to evaluate the validation data and understand existing literature, and to carry out a comprehensive validation of the accuracy of the models. Where necessary and as time allows, the model validation can be improved by optimization and tuning. All updates will be validated against experimental data. This internship will be situated in the SaCoMo group based in The Hague, Netherlands.

Objectives

- Research signal analysis and numerical techniques

- Understand model usage and safety engineering approaches

- Develop analysis process

- Analyse experimental data and draw conclusions

- Extend methodology to support engineering methodology

Requirements

The methods will be developed within the group, with feedback from colleagues. They will need to be straightforward to implement. If the work is successful, Siemens would support academic publication/presentation of the work.
