Wedge Damper Modeling and Forced Response Prediction of Frictionally Constrained Blades

Friction analysis in cold forging Cora, Ömer Necati; Akkök, Metin; Department of Mechanical Engineering (2004) Friction is one of the important parameters in metal forming processes since it affects metal flow in the die, forming load, strain distribution, tool and die life, surface quality of the product etc. The range of coefficient of friction in different metal forming applications is not well known and the factors affecting variation are ambiguous. Commercially available FEA packages input the coefficient of friction as constant among the whole process which is not a realistic approach. In this study, utility o...
Torque and drag field applications in horizontal wells EREN, TUNA; Caglayan, Burak Kagan; Kök, Mustafa Verşan (2017-01-01) The industry of drilling for oil, gas geothermal, and storage purposes necessitates construction of challenging wells in recent applications. Challenging wells are required to be designed prior to the drilling to selection of the equipment to be utilised while drilling. A poor engineering planning may result in losing time and effort to remediate torque and drag related troubles which might be encountered. Adequate planning is significantly important which is going to reveal possible drawbacks in planned we...
Shear Capacity N-M Interaction Envelope for RC Beam-Column Joints with Transverse Reinforcement: A Concept Derived from Strength Hierarchy Tasligedik, Ali Sahin (Informa UK Limited, 2020-06-01) Strength hierarchy assessment method is a capacity analysis procedure that can be used to identify the sequence of failures likely to occur within reinforced concrete (RC) frame buildings under lateral actions such as earthquakes or wind loads. Previous publication on this method mainly focused on the application of this method to (a) the vulnerable RC beam-column joints without any joint shear reinforcement where principal tensile stresses were considered critical,(b) modern RC beam-column joints with join...
Friction identification and compensation of its effects in stabilized platforms Sincar, Eyyüp; Balkan, Raif Tuna; Platin, Bülent Emre; Department of Mechanical Engineering (2013) A frequent problem encountered in the stabilization of a dynamic system supported by a moving base is the disturbance rejection associated with moving components. Due to relative motion of adjacent components, the friction induces a destabilizing force from base motion to the stabilized object, which degrades the motion accuracy. Therefore, the compensation of frictional effects is necessary in order to obtain a highly precise stabilization performance, especially, when the stabilized system undergoes low-v...
