This paper outlines an approach to simulate and validate the attenuation performance of Integrated Helmet Display
designs within BAE Systems. The validation studies are performed at material coupon, sub-system and system levels of
Display and Helmet designs to facilitate integrated Display Helmet model development and allow a rigorous assessment
of model accuracy. Simulation results are presented which show close agreement with the shape of the acceleration
history and peak acceleration values obtained in laboratory scale qualification tests conducted at the British Standards
Institute (BSI). The final system level model provides a detailed insight into the key characteristics which effect
attenuation performance in Integrated Display Helmet designs.
The overall aim of this work is to develop and validate models which can be used to assess the influence of design
modifications on current and future Display Helmet products within BAE Systems. The application of simulation for
product development is regarded as a key driver within BAE Systems to reducing the development cost of Helmet
Mounted Display (HMD) products and improving product performance.
