Modeling And Simulation Of Horizontal Axis Washing Machine

In this paper, a rigid-flexible multi-body virtual prototype model built with ADAMS for a horizontal axis washing machine was presented. Based on the horizontal axis washing machine virtual prototype modeling and analysis, understood the dynamics properties of the washing machine, and prepared the condition for a new type of horizontal axis washing machine virtual platform for further research and development. This research method provided practical engineering value for the washing machine industry.In this paper, a virtual prototype model was performed for a horizontal axis washing machine with CAD and CAE software, such as Pro/E, MSC.Adams, MSC.Nastran and MSC.Patran. In this process, the following was the major work.(1) In order to build a precision model of the damper, which is most important in the virtual prototype, a series of experiments were designed for obtaining the damper's dynamic characteristics.(2) In this model the cabinet was treated by the finite element method as a flexible body, and other parts was rigid. To ensure coherence between the FEM model and the actual physical model, the Normal Modes Testing was performed on the cabinet.(3) While recognizing the correctness of the rigid-flexible multi-body virtual prototype model, lots of simulations were performed, including the vibration analysis in frequency domain and time domain analysis of the washing and spin. Finally, with the simulation results, some recommendations were given for horizontal axis washing machine design.
