Abstract
In a device for recovering metallic sodium from sodium slag, the bearing support structure that supports and drives the rotation of the distillation furnace is one of the key components that cause the failure of the device, and its failure form is insufficient strength. In this paper, under the condition of certain material parameters, the bearing mechanism's loadbearing capacity is analyzed by finite element analysis, and the design and optimization of the bearing mechanism based on the response surface method are carried out to guide the fit between the parts in the device. Then establishing a reliability model, the design results were evaluated for their reliability based on the Six Sigma module, which improves the overall reliability of the device. The results show that the maximum equivalent force of the bearing support structure is about 15.066 MPa, which is much smaller than the default structural steel material yield strength of 235 MPa. The maximum deformation after optimization is about 0.02 mm higher than before, which has little impact on the device. This method has a little guiding meaning for similar assembly reliability analysis.
