Dynamic modeling and analysis of drum-type washing machine 总被引:1,自引:0,他引:1
Hee-Tae Lim Weui-Bong Jeong Keun-Joo Kim 《International Journal of Precision Engineering and Manufacturing》2010,11(3):407-417
In this study, dynamic analysis of a drum-type washing machine has been conducted using a simplified dynamic model considering
gyroscopic effects. Its mathematical model has 6-degree of freedom in the complex coordinate space into which is transformed
real coordinate space to understand the whirling motion easily. Dynamic analysis is performed using MATLAB. For the purpose
of numerical verification, the results for unbalance response are presented and compared with the experimental vibration test.
The mathematical model proves quite good accuracy in predicting dynamic characteristics which could be changed by the parameters
of design variable and can reduce design cycle shortly. Dynamic characteristics of a washing machine are shown through shape
and directivity index (SDI), whirling orbits, rigid and flexible mode of a drum type washing machine during drum run-up. In
designing drum type of washing machine, it is efficient than finite element method to analyze behaviors of drum and tub. 相似文献

In this article, a new magneto rheological (MR) sponge damper is proposed for suppression of vibrations in a washing machine. The article presents design optimization of geometric parameters of MR sponge damper (MRSD) using the finite element analysis (FEA) and first order derivative techniques for a washing machine. The article explains the hysteresis behavior and the relationship of damping force with input current for the proposed MRSD. Moreover, the characteristics of the MRSD such as energy dissipation and equivalent damping coefficient are investigated experimentally in terms of input current and excitation amplitude. The passive dampers installed in washing machine are ineffective in reducing unwanted vibrations at resonant frequencies due to real time unbalanced mass. For this purpose, a test setup is established in order to compare the performance of passive dampers with the proposed MRSDs in a washing machine. It is noticed that MRSDs reduce average vibrations of 75.61 % in a low frequency band, whereas in a high frequency band, the MRSDs lessen average vibrations of 30.57 % in a washing machine. In order to determine the performance of proposed design MRSD, a detailed comparison of the performance parameters, such as total damping force, passive force, maximum average vibrations after suppression by MR dampers, maximum current and power ratings is provided with the existing designs of MR damper for washing machine from the literature. 相似文献
