摘要: 考虑上配重对洗衣机悬挂系统振动的影响,基于拉格朗日方程,对该系统进行动力学建模。进行了多工况下的洗衣机筒体振动测量实验,以实验得到的筒体振幅随转速变化的关系曲线为目标,对数学模型进行了参数修正。通过数值仿真与实验结果的对比分析,验证了动力学模型的正确性。

Abstract: Considering the effects of top balancing weights of washing machine suspension system, a dynamics model of this system was set up with Lagrange equations. Experiments were designed to measure vibrations of washing machine drum under multiple working conditions. An modification for parameters of dynamics model was performed based on the relation curves between the vibration amplitudes and speeds of the drum. The results calculated by dynamics model were compared with those obtained by experiments. The validity of dynamics model was verified. 

Key words: washing machine, horizontal-axis, suspension system, top balancing weight, dynamics model, vibration measurement
