| 本文利用ANSYS有限元分析軟件對FCB法三絲埋弧焊的溫度場進(jìn)行數(shù)值模擬,在考慮焊絲偏轉(zhuǎn)的情況下,通過對雙橢球形熱源進(jìn)行疊加,建立了三絲埋弧焊的焊接熱源模型。采用不同的網(wǎng)格劃分方式,節(jié)省了模擬計算的時間及計算機(jī)所占用的資源,并利用ANSYS參數(shù)化設(shè)計語言,實現(xiàn)了三絲埋弧焊熱源熱流密度的計算和移動加載。通過不斷調(diào)整雙橢球熱源模型的形狀參數(shù),最終使模擬計算的結(jié)果與實際焊接得到的結(jié)果相符,并確定最佳的模擬方案。 |

Considering the deflection of welding wire, the heat source model of three wires submerged arc welding was established by overlaying the double ellipsoidal heat source. Through adopting different meshing ways, we saved time in analog computation and saved computer resource occupation, and with the application of parametric design language of ANSYS, we realized the computation of heat source flux density as well as the moving heat source load of three wires submerged arc welding. By repeatedly adjusting the shape parameter of double ellipsoidal heat source model, the analog computation results were eventually matched with the results obtained by practical welding process, and thus the optimal simulation scheme was determined. |
