Study On Optimization Of Dynamic Characteristics Of Dehydrator Based On Response Surface Methodology

As a kind of common white household appliances,the sound and vibration performance of washing machine not only deeply affects the life experience of users,but also determines its future development direction.In order to find out the superiority of sound and vibration performance of washing machine.In this paper,a wave-wheel dehydrator is taken as the research object,and the ultimate goal is to get better parameters combination of suspension system.Based on theoretical research,experimental research and simulation research,the dynamic optimization of stiffness and damping values of suspension components in multi-degree-of-freedom direction is studied.Based on vector analysis method and Lagrange equation,the dynamic model of the research object is established.Modal test,cylinder amplitude test and parameter test are carried out around the solid prototype model of the dehydrator.The reliability of the model and the standardization of the test are verified by comparison.In this paper,the virtual prototype model of the research object is established by using ADAMS software,and the reliability of the virtual prototype model is verified by data.Based on the theory of response surface methodology and virtual prototype model,the response surface model of the cylinder amplitude and key parameters of the dehydrator is fitted,and the reliability of the response surface model is verified.Reasonable selection and improvement of optimization algorithm are carried out to optimize the parameters of the response surface model.The final results are obtained and validated by substituting the optimized parameters into the virtual prototype model.The validation results show that the vibration suppression performance of the wave-wheel dehydrator has been significantly improved.
