Lupker, H. (author), Lemmen, P. (author), Ploeg, J. (author), TNO Wegtransportmiddelen (author)Pre-Crash Systems (PCS) use environment sensors and electronic control functions to improve the effectiveness of passive safety devices by activating them before a collision occurs. In view of the autonomous character and high demands on reliability, dedicated design tools and methodologies are required. PreScan, MADYMO and VEHIL and their...conference paper 2006

Boucher, H. (author), Waagmeester, C.D. (author), TNO Wegtransportmiddelen (author)To improve survivability and to minimize the risk of injury to occupants in helicopter crash events, a complete Cabin Safety System concept including safety features and an enhanced FAA-Hybrid III dummy were developed within the HeliSafe project. A numerical tool was also created and validated to allow simulations of various crash scenarios. The...conference paper 2003

Verver, M.M. (author), van Hoof, J.F.A.M. (author), TNO Automotive (author)The importance of comfort for the automotive industry is increasing. Car manufacturers use comfort to distinguish their products from their competitors. However, the development and design of a new car seat or interior is very time consuming and expensive. The introduction of computer models of human and seat could accelerate this process. This...article 2002

Verver, M.M. (author), van Hoof, J.F.A.M. (author), Society of Automotive Engineers (author)The importance of automotive comfort is increasing, both socially and economically. Especially professional drivers often have comfort-related physical complaints, such as lower back pain. In addition, car manufacturers can use comfort to distinguish their cars from their competitors. However, the development and design of a new, more...conference paper 2002

Rekveldt, M.G.C. (author), Swartjes, F.H.M. (author), Steenbrink, A.C. (author), TNO Wegtransportmiddelen (author)There is an increasing pressure to reduce injuries and fatalities by effectively using airbags for side impact and out-of-position impact loading conditions. Numerical simulation, as an essential design tool for airbags, requires accuate models applicable to the various OOP loading cases. In this paper a strategy for defining such models...conference paper 2002
