Analysis of the Temperature Influence on a Shift of Natural Frequencies of Washing Machine Pulley

The temperature influence on a shift the natural frequencies of washing machine pulley is investigated in this paper. The numerical analysis for the four different temperatures was performed. The experimental modal analysis at the temperature 20°C for the control of natural frequencies and the mode shapes obtained from the numerical analysis at the temperature 20°C, was performed. The numerical modal analysis agrees well with experimental modal analysis and it can be used for prediction the natural frequencies and the mode shapes.
