【Abstract】Toaddresstheissuesofdeformationandcrackingintheinnerringof thepistonseatboreon electric forklift brakeendcoverscaused byexcessivebrakingloadsduring parking，thisstudyemploysANSYS finiteelementanalysis （FEA） softwaretoconduct static structuralanalysisunderboth fullyloadedandunloaded conditions.Thestaticanalysis resultsre veal thatunderunloadedconditions，themaximum stressandstrainonthe innerringofthepistonseatboreremain withinthe allwablelimits，metingoperationalrequirements，andunderfullloadedconditions，themaximumstressandstrainexceed permissiblevalues，leading toyielddeformationand，inseverecases，crackingof theinnerring.Consideringtheconomic andlightweightrequirementsofelectricforklifts，anoptimizationstrategyinvolvingmoderatethickeningoftheinneringis proposed.Post-optimization staticanalysis demonstrates thatasignificantreductioninboth maximum stressand strainon the pistonseatboreinnerringandallmechanicalperformance indicators nowfallbelowallowablelimits，ensuringreliable brakingperformance.Thestudyconcludesthatstaticanalysisandoptimizationof thebrakeendcoverduring instantaneous parking braking effectivelymitigates deformationandcracking inthepistonseatbore.Thisapproachprevents braking failures and reduces unintended vehicle movement accidents，enhancing operational safety.
