Schwingungsgestuetztes Nutzfahrzeug-Fahrerhaus durch aktive Federung. T. 1 Bewertung der mechanischen Schwingungseinwirkung auf den Menschen im Kraftfahrzeug. Literaturrecherche. Schlussbericht

Frequently the cab of a commercial vehicle is for the driver and codriver the permanent place of work. The exposure to vibration when driving is characterized by the amplitude and frequency on one hand and the long exposure time on the other. Measures to improve the vibrator isolation have to take into account the biomechanical behaviour of the human body. At the beginning of this research project the knowledge about the human exposure to vibration has been compiled in a literature review. The main result is that apart from the frequency dependence for harmonic oscillations, stochastic and multiaxial excitations are of major importanceSIGLEAvailable from TIB Hannover: F93B1063+a / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Forschung und Technologie (BMFT), Bonn (Germany)DEGerman

Hochleistungsverbundwerkstoffe mit einer hochreaktiven Epoxidharz/Haerter-Matrix und dreidimensionalen Fasergeruesten fuer Serienbauteile (S-RIM)

Series production of high-performance composite materials consisting of reinforced epoxy resin can be realized by structural reaction injection molding (S-RIM) using preformed fibre structures and injecting the epoxy resin/hardener mixture. The new epoxy resin/hardener system developed for the S-RIM process is characterized by high reactivity, low viscosity at process temperature (100 mPas at 95 C), good fibre wetting power, glass transition at >120 C and a hardening velocity of about 1 min per 1 mm wall thickness. Prototyping has been demonstrated with a frame carrier component for cargo trucks.

From Attractio and Impulsus to Motion of Liberty : Rarefaction and Condensation, Nature and Violence, in Cardano, Francis Bacon, Glisson and Hale

There was a particular way of understanding and explaining changes in matter's quantity whose first exposition can be traced back to the Renaissance in Girolamo Cardano's classification of the natural motions of the universe, particu- larly in the motions of impulsus (impenetrability) and attractio (abhorrence of a vacuum). Cardano's exposition was read attentively by Francis Bacon, whose idea of "motion of liberty" both modified and retained elements of the Cardanian view. The Baconian treatment of the motion of liberty made its way well into the seven- teenth century in the works of Francis Glisson and Matthew Hale, who draw heavily on it to provide their own account of rarefaction and condensation. The aim of this essay is to reconstruct the history of the accounts of the processes of rarefaction and condensation held by these authors in order to examine the ramifications of the Cardanian approach in the seventeenth century. This history will not only provide us with new instruments for understanding the intellectual relationship between the Renaissance and the early modern period but also improve our understanding of the transformation of the world picture across the emergence of early modern science.Fil: Manzo, Silvia.
