Periodic Reporting for period 2 - HEADS (Head protection: a European training network for Advanced Designs in Safety)
Reporting period: 2017-01-01 to 2018-12-31
To date, it is linear acceleration that has been used most to determine head injury risk, although brain injury is influenced by angular kinematics. The scientific goal of the HEADS Network was to improve our understanding of head impact injury by taking account of rotational kinematics. This would result in improved helmets and a reduction in fatalities and the severity of injuries. This scientific objective was achieved through computer simulations and experimental reconstructions of real-life accidents, combined with new tests to determine injury thresholds and to certify new helmets. The Network’s industry partners manufacture high quality helmets for equestrian sports, cyclist and F1 motorcyclists; our 3rd level partners already provide international leadership in this field of research. The mix of industry and academia in this project was ambitious, comprehensive and goal oriented.
The Network also intended to train a group of highly specialised PhD graduates who were cognisant of head impact biomechanics, helmet design technologies, and were aware of commercial market opportunities. The ESRs worked with world class facilities and highly qualified experts; they benefited from a training scheme which will draw on the expertise of academic and industrial partners.
This research from this project provides a new level of understanding of head injury and its prevention, with directly applicable results for European industry. It's objective was to develop a well networked group of young engineers and scientists into world class researchers and innovators with numerous career paths open to them. These professionals will advance technology for the benefit of society to maintain Europe as a global leader in industrial development.
In summary, the Network’s objectives were to:
• develop new understanding of head impact injury and injury thresholds for rotational kinematics
• design new helmet standards test methods that recognise the importance of head rotational kinematics in head injury
• train an elite cohort of ESRs in the multidisciplinary field of head impact protection, who will have a unique blend of commercial and industrial market awareness
The Network consortium consists of 6 partners, each of them leaders in their fields.
• University College Dublin, Ireland (NUID UCD)
• Kunliga Tekniska Hoegskolan, Stockholm, Sweden (KTH)
• Katholieke Universiteit Leuven, Leuven, Belgium (KU Leuven)
• Charles Owen & Company Ltd, Wrexham, UK (Charles Owen)
• Lazer Sport NV, Belgium (Lazer Sport)
• AGV SPA, Italy (AGV)
The blend of partners ensured that ESRs received a multidisciplinary approach to their training, and experience of academia and industry, thereby ensuring that their research was relevant to real world solutions.
• WP1 Management of Network
• WP2 Training Programme

o Investigating thresholds for neuronal damage in head models
o Analysing brain tissue characterization thresholds for brain contusion
• Developing new equestrian helmet standard tests for improved head impact protection
• Seeking to develop a more biofidelic headform
• Developing new cycling helmet standard tests for improved head impact protection
• Developing new motorcycling & snow sports helmet standard tests for improved head impact protection
• Characterisation and analysis of energy absorbing materials under compression/shear for helmet liner applications
- Publishing 40 Journal Publications, Conference Proceedings and Reports - many of them being of a joint publication status or showing inter work package collaboration.
The project partners met all deliverables and milestones.
The collaboration between the HEADS Network partners and their ESRs proved productive and successful. The team’s positive dynamic resulted in cooperative and positive teamwork and partnership across a variety of research environments. There is great enthusiasm for what the HEADS Network research yielded and for the impact that the research will have on society.
It has been recognised that there is an absence of a structured research programme that will improve helmet standards within the EU. The HEADS ITN aimed to overcome the challenges of fragmented or duplicated research and to address this deficit. Through its collaborative approach, training workshops, and outreach and secondment opportunities, the Network was effective in transferring and sharing the expert subject knowledge.
Finally, all industry partners were engaged in the research being carried out by the HEADS team. Integrating the research results into their helmet products continues to be a work in progress.
