Designing cars for expectant mothers

04.09.2009
UK researchers have developed a new computer model - Expecting - that can be used as a design tool for automotive designers to help ensure that vehicle designs can accommodate the safety needs of pregnant occupants. They report details in the latest issue of the International Journal of Vehicle Design.

Serpil Acar of the Department of Computer Science, at Loughborough University, Alix Weekes (now at Thatcham MIRRC), and David van Lopik (now at Atkins Aviation and Defence Systems), have worked within a comprehensive research program at Loughborough University to improve pregnant occupant safety.

The overall aim is to produce a pregnant occupant model capable of simulating the dynamic response to impact and predict the risk of injury in automobile crashes.

There are almost three quarters of a million pregnancies in the UK each year and it is fairly certain that a large number of those expectant mothers will at some point during their pregnancy drive, or be a passenger in a vehicle. Thousands are involved in accidents each year and while a relatively small proportion will die, many more will suffer injuries.

The researchers explain that the safety of pregnant women is often compromised because of the changes in their body size and shape that occur during pregnancy. These changes are not limited to the abdominal region, but affect the chest and thigh areas, all of which can affect sitting and driving posture and seat belt use.

Inappropriate seat belt is a significant problem for pregnant women. It is often difficult and sometimes impossible for a pregnant user to get her seat belt into a comfortable position. As such many women take unsafe actions, either hold the belt away from their bodies while the vehicle is moving or do not use a seat belt at all.

Another problem is pressure on the abdomen from the steering wheel in the event of a crash. Researchers have found that more than one in ten pregnant women find the gap between their abdomen and the steering wheel is less than 2.5 cm and for some there is no gap at all. This proximity to the steering wheel may put the placenta at increased risk of abruption from direct impact with the steering wheel.

Acar and Weekes have taken 48 different measurements from 100 pregnant women in different postures and at different terms in their pregnancy to help Acar and van Lopik to create their computer model. The measurements show that even the designers that take into account the measurements of larger men, may still exclude majority of women at the late stages of pregnancy.

‘Expecting’, has been further developed to be the world’s first computational model of a 38-week pregnant car occupant, complete with a detailed representation of a foetus within uterus and it is now used in further research, together with MADYMO, in the simulation of crash scenarios.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
