Structural Optimization Design and Experimental Verification of Elastic Support Bearing Outer Ring Based on Response Surface Method
In order to improve the accuracy of the outer ring stiffness design of the elastic support bearing,ANSYS Workbench was used to simulate and analyze the static stiffness of the outer ring of three different parameter structures,and the maximum deformation of the outer ring under different loads was obtained.The least squares method was used to analyze the linear relationship between load and deformation,the stiffness value of the outer ring was determined,the finite element model of the outer ring that met the actual stiffness requirements was obtained,and response surface optimization analysis was made.Taking the stiffness value as the optimization goal and the width,length and number of the outer ring elastic support beam as the design variables,the outer ring of the elastic support bearing was analyzed through the response surface optimization to obtain the optimal design parameters.In order to ensure the accuracy of the optimization results,theoptimal model was re-analyzed for finite element analysis and experimental verification.By comparing the de-sign scheme of the optimal solution with the initial design scheme,the results show that the stiffness optimization result of the optimal design solution and the target error value is less than 1％under the premise of satisfying the constraint range of the design variables.It can be seen that the response surface optimization improves the processing efficiency,shortens the design cycle,and further improves the accuracy of the supporting stiffness.
