Formulation and implementation of parametric optimisation of a washing machine suspension system

Towards a durability test for washing-machines

“…The system kinematics of WMs has been studied by scientists ( Bae et al, 2002 , Chen et al, 2015 , Conrad and Soedel, 1995 , Nygårds and Berbyuk, 2012 , Türkay et al, 1995 ) and even more by industry to find the ideal compromise between the imbalance occurring during the spinning of the load, spring dimensioning, damper characteristics and the gravimetric weight of the whole oscillating system. The lower the maximum imbalanced mass expected, the less the gravity mass of the whole ‘swinging’ system needs to be or the lower the space between tub and housing must be.…”

Dynamical Behaviour of the Planar Non-Linear Mechanical System — Part I: Theoretical Modelling

“…Thus, only the bicoherence values greater than equation (13) and lower than equation (14) are considered for QPC detection. The power spectra were calculated by using 4096 FFT points per segment.…”

“…The washing machine's suspension optimization was conducted [14] on the washing complex modelled as a rigid body with 6 d.o.f. The aims were orientated towards several directions.…”

Dynamic Analysis of an Automatic Washing Machine With a Hydraulic Balancer

“…They carried out theoretical and experimental dynamic analyses for transient and steady state conditions. Later, the validated model was used to optimize the spring sti!ness of suspension and the two dry-friction coe$cients of shock absorber and lateral damper [4,5]. They used an optimization routine that minimizes the maximum displacements for transient and steady state conditions subjected to the constraint of inequality of stepping forces.…”
