In this study, a nonlinear mathematical model for drum-type washing machines is developed considering rotating unbalance type excitation. Nonlinear differential equations of motion are converted into a set of nonlinear algebraic equations by using harmonic balance method (HBM). The resulting nonlinear algebraic equations are solved by using Newton’s method with arc-length continuation. Several case studies are performed in order to observe the effects of orientation angles of springs and dampers supporting the drum. In order to reduce the steady-state vibration amplitude of the drum and transmitted force through springs and dampers, suitable spring and damper orientation angles are identified. Moreover, in order to further reduce the vibration amplitude of the drum, dry friction dampers are introduced to the system. It is clearly observed that dry friction dampers are solving the walking problem of washing machines.

Nonlinear modeling and vibration analysis of horizontal drum type washing machines
Baykal, Cem; Yazıcıoğlu, Yiğit; Department of Mechanical Engineering (2019)
Nonlinear two and three-dimensional dynamical models for horizontal drum type washing machines are developed considering rotating unbalance type excitation. Nonlinear differential equations of motion are converted into a set of nonlinear algebraic equations by using the Harmonic Balance Method (HBM). The resulting nonlinear algebraic equations are solved by using Newton’s method with arc-length continuation.

Nonlinear vibration analysis of functionally graded beams
Dedeköy, Demir; Ciğeroğlu, Ender; Bediz, Bekir; Department of Mechanical Engineering (2022-8)
In this thesis, nonlinear forced vibrations of functionally graded (FG) Euler-Bernoulli Beams are studied. Two types of nonlinearities, large deformation nonlinearity and nonlinearities resulting from rotating beam dynamics, are considered. The Spectral Chebyshev Technique (SCT) is employed for solving governing equations of the spectral-temporal boundary value problems of beam vibrations, which do not always have closed-form analytical solutions. The SCT is combined with Galerkin’s method to obtain spatial...
Nonlinear Vibrations of a Beam with a Breathing Edge Crack
Batihan, Ali C.; Ciğeroğlu, Ender (2015-02-05)
In this paper, nonlinear transverse vibration analysis of a beam with a single edge crack is studied. In literature, edge cracks are generally modeled as open cracks, in which the beam is separated into two pieces at the crack location and these pieces are connected to each other with a rotational spring to represent the effect of crack. The open edge crack model is a widely used assumption; however, it does not consider the nonlinear behavior due to opening and closing of the crack region. In this paper, a...
Adaptive Harmonic Balance Methods, A Comparison
Sert, Onur; Ciğeroğlu, Ender (2016-01-28)
Harmonic balance method (HBM) is one of the most popular and powerful methods, which is used to obtain response of nonlinear vibratory systems in frequency domain. The main idea of the method is to express the response of the system in Fourier series and converting the nonlinear differential equations of motion into a set of nonlinear algebraic equations. System response can be obtained by solving this nonlinear equation set in terms of the unknown Fourier coefficients. The accuracy of the solution is great...
