Universidad de Zaragoza (orcid)0000-0003-3909-5599 Washing machine dynamic model to prevent tub collision during transient state 2020 Access copy available to the general public Unrestricted In horizontal-axis washing machines, the front gasket as well as the damping system are crucial owing to the possible collision of the tub with the housing during the transient period. However, most dynamic models for predicting tub motion focus on the steady state and consider only the suspension system without including the gasket. We conducted an experimental study to analyze the effect of the gasket on the transient motion of the tub. The results obtained indicate the necessity of implementing the gasket in the multibody model of a washing machine to accurately predict the tub behavior during this period. The gasket model is formed by a combination of Voigt elements. Stiffness parameters are determined using a load cell, and damping factors are estimated using a process that integrates Adams/View, Matlab optimization algorithms, and displacement measurements that are taken using accelerometers. A D-optimal design used to predict the effect of the gasket parameters reveals that the tub displacement is most sensitive to the changes in linear stiffness in the transversal direction. Finally, the model of the gasket provides a better approach for predicting the tub movement during resonance that can be used in the design phase to avoid tub collision. info:eu-repo/grantAgreement/ES/DGA/E41-20R info:eu-repo/grantAgreement/ES/DGA/T19-20R info:eu-repo/grantAgreement/ES/MCIU/PID2019-104263RB-C43 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.576 2020 INSTRUMENTS & INSTRUMENTATION 14 / 64 = 0.219 2020 Q1 T1 CHEMISTRY, ANALYTICAL 26 / 83 = 0.313 2020 Q2 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 82 / 273 = 0.3 2020 Q2 T1 0.636 2020 Analytical Chemistry 2020 Q2 Atomic and Molecular Physics, and Optics 2020 Q2 Biochemistry 2020 Q2 Medicine (miscellaneous) 2020 Q2 Information Systems 2020 Q2 Instrumentation 2020 Q2 Electrical and Electronic Engineering 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Galé, C.
