3. 2. Berechnung der Zahnfußspannungen von Beveloidverzahnungen

   Författare :Jannik Henser; Christian Brecher; Christian Brecher; Peter W. Gold; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Beveloid gears are conical gears which are derived from cylindrical involute gears to transmit torque and rotation for parallel, intersecting or skew axes. While defined by the same data as cylindrical involute gears, the addendum modification factor, however, changes linearly to the tooth width. LÄS MER

4. 3. Behaviour of Piles with Enlarged Tip in Non-Cohesive Soil. Model Tests and Numerical Simulations

   Författare :Torbjörn Edstam; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical simulations; plasticity; model tests; enlarged tip; piles; large strains; sand;

   Sammanfattning : Slender piles reduce detrimental vibrations during installation. In order to preserve a high bearing capacity, the pile tip can be enlarged after installation. This study consists of model tests of conventional piles (unexpanded piles) and piles with enlarged tip (expanded piles). LÄS MER

5. 4. Footing with Settlement-Reducing Piles in Non-Cohesive Soil

   Författare :Duc Long Phung; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Although the design concept based on the idea of limiting the settlement of footings by settlement-reducing piles is gaining more and more support, there have been very few experimental studies of the behaviour of piled footings in non-cohesive soil. The influences of the contact between the pile cap and the soil on the capacity and the load-settlement behaviour of a piled footing are considerable but this has not been well understood. LÄS MER

7. 5. Thermohydrodynamics of sliding contacts with textured surfaces

   Författare :Samuel Cupillard; Paul Allaire; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : Hydrodynamic sliding contacts like those found in journal or thrust bearings are frequently encountered in various types of machinery from computers to large turbines. These contacts, involving a variation in film thickness, are used to generate pressure in the lubricant film and separate the surfaces in relative motion. LÄS MER
