Torsional Natural Frequency Analysis Of Torsional Vibration Damper Using Numerical And Modal Test Approaches

SEZGEN, Haşmet Çağrı

This work presents to obtain the torsional natural frequencies and mode shapes of the torsional vibration damper. The torsional vibration damper is mounted on the end of the crankshaft in the opposite direction of the flywheel to dampen the torsional vibrations, especially high-torque diesel engines. The torsional vibration damper used in the study consists of thirteen elements include rubber, silicone and other materials. Therefore, in this study, the Holzer, matrix, finite element methods and modal test are realized to determine the torsional natural frequencies and mode shapes of the propos ...Daha fazlası

Static analysis of laminated composite beams based on higher-order shear deformation theory by using mixed-type finite element method

ÖZÜTOK, Atilla | MADENCİ, Emrah

In this paper, mixed finite element (MFEM) equations which are based on a functional are obtained by using the Gâteaux differential (GD) for laminated composite beams. Higher-order shear deformation theory (HOBT) including non-linear distribution of shear stress through thickness of laminated beam is presented. Differential field equations of composite beams are derived from virtual displacement principle. These equations were trans- formed into the operator form and using the mathematical advantages of the proposed the variational method, a functional with geometric and dynamic boundary condi ...Daha fazlası

Torsional Natural Frequency Analysis Of A Cranktrain System Using Holzer And Finite Element Method

SEZGEN, Haşmet Çağrı

This study aims to obtain the torsional natural frequencies and mode shapes of the twelve degrees of freedom cranktrain system consisting of a flywheel, crankshaft, and torsional vibration damper elements using Holzer and finite element methods. An equivalent lumped mass model of the proposed cranktrain system is created by considering twelve masses connected with spring and damping elements. In equivalent modeling approach, eight elements of the lumped mass model are connected in series, the rest four masses are connected by three parallel branchings. Also, these four masses express the torsi ...Daha fazlası

Variational approximate for high order bending analysis of laminated composite plates

MADENCİ, Emrah | ÖZÜTOK, Atilla

This study presents a 4 node, 11 DOF/node plate element based on higher order shear deformation theory for lamina composite plates. The theory accounts for parabolic distribution of the transverse shear strain through the thickness of the plate. Differential field equations of composite plates are obtained from energy methods using virtual work principle. Differential field equations of composite plates are obtained from energy methods using virtual work principle. These equations were transformed into the operator form and then transformed into functions with geometric and dynamic boundary co ...Daha fazlası

Variational Approximate and Mixed-Finite Element Solution for Static Analysis of Laminated Composite Plates

MADENCİ, Emrah | ÖZÜTOK, Atilla

The main objective of the present study is to give a systematic way for the derivation of laminated composite plates by using the mixed type finite element formulation with a functional. The fırst order shear deformation plate theory is used. Differential field equations of composite plates are derived from virtual displacement principle. These equations were written in operator form then by using the Gateaux differential method, a new functional which including the dynamic and geometric boundary conditions is obtained after provide potential conditions. Applying mixed­type finite element base ...Daha fazlası
