   Sammanfattning : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. LÄS MER

3. 2. Design and construction of a contactless excitation and response measurement system

   Sammanfattning : Manufacturing industry works on Overall Equipment Effectiveness (OEE) to increase the yield and speed of machining. A good knowledge of the machine properties is important to increase the speed while still maintaining stable cutting with low tool usage. LÄS MER

4. 3. Skarven : – Produktutveckling av en oljedimavskiljare

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Sammanfattning : This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. LÄS MER
