As an application of this fem preprocessing system, the simulation on the welding process of missile ’ s oil box was performed, in which the effects of the welding sequences of four web plates and welds on each web plate are primarily analyzed. the simulation results show that the deformations under varied welding sequences are almost the same. downward deflection deformation is obtained along the weld longitudinal direction in the structure as well as upward deflection deformation along the weld traverse direction
對于某型號導彈油箱結構焊接過程的數值模擬計算，主要考察了每塊立板上各段焊縫焊接順序的調整、四塊立板之間不同的焊接順序以及焊接起始端的選擇對結構焊后變形的影響規律，模擬結果表明:壁板在各種焊接順序下的整體變形規律基本相似，即焊後壁板沿焊縫縱向發生了向下的撓曲變形，中部向下變形量最大;沿焊縫橫向發生了向上的撓曲變形，壁板兩端部變形量較大，且壁板前端變形大於壁板後端。 -
The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased
本文利用數值模擬手段對轉輪的焊接工藝從分段焊和局部加熱兩個方面進行了優化，結果表明:採用普通工藝焊接時，葉片焊后殘余拉應力出現在焊縫及其附近區域，並且在葉片出水邊的熔合線附近（危險區域）出現了峰值;在採用優化的分段焊時，先焊兩端后焊中間的方法可以降低葉片危險區域的焊接殘余拉應力峰值，降低效果與葉片出水邊焊段長度、焊縫各段的焊接方向有關;局部加熱法降低轉輪危險區域殘余應力的效果主要與加熱時間、加熱溫度以及加熱面積成正比，與冷卻面積成反比，並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。 -
