Abstract：Themain failuremodeof balancedarmaturerelays during operationiscontact ablation in the contact system，which iscaused bylarge dispersionin the pull-inspeedduring therelay’spullin process. Excessively highpull-inspeed canlead tocontactbounce，while excessivelylow pull-inspeed can result in poor pullin.Taking a certain type of productas the research object，a method for consistent parameter design and tolerancedesign basedondigital models isproposed.Byestablishingan electromagnetic-mechanical co-simulation model of the entire machine，the influence laws of key parameters suchas contact gapand initial pressre on the pull-in speed are analyzed.After optimization，the average pull-in speed is reduced to 0.3224ms ，and the standard deviation isdecreased by 17.9% .Through tolerance design，the standard deviationis further reduced by （204号 34.3% ．The tests show that the proposed method can effectively suppress contact bounce and arcing phenomena， and improve the product quality consistency.
