Abstract：Inorder torealizethelightweightofautobody，the traditional one-pieceBIWdashboardpanel is designed intotwoparts （theupperone andthelowerone）with differentthickness.According to the typical featuresof the front dashboard panel，namely thearch shape of theevacuation area of the wheel cover，this paper proposes shallow drawing plusreshaping tosimplify stamping processand greatly improve materialutilization rate.Inorder to address theisuesofcorrugationof dashboardupperpanel，insufficient stiffnessof singlepartandpoorwelding of evacuation area of the wheel cover，the paper verifies the feasibility of shallow drawing plus reshaping through stamping CAEanalysis，stamping physical production and welding quality verification.The cost saving advantage of split-type front dashboardpanel isconfirmed bythe cost accounting of the whole processchain （stamping，welding， coating）.Finally the low-cost front dashboard panel is put into mass production withshallow drawing plus reshaping process.
