章節(jié)摘錄

插圖：2.5差分方程的確定在實(shí)際計(jì)算中，選用有限差分方程，對(duì)于邊界點(diǎn)采用中心差商的方法處理，時(shí)間步距選取0.0002s。具體過(guò)程從略。3計(jì)算結(jié)果分析利用上述的計(jì)算結(jié)果，分別做出0.3s，0.6s，0.7s時(shí)刻的橫截面、縱橫面的溫度分布圖。當(dāng)焊接時(shí)間小于0.3s時(shí)，由于接頭發(fā)熱量不足，在焊件的各個(gè)截面上，其溫度均不能達(dá)到使聚乙烯軟化的程度，從理論上講是不能完成焊接的.實(shí)際上在所完成的試驗(yàn)中，也可以看到，在焊接時(shí)間小于0.3s時(shí)，無(wú)論怎樣調(diào)整各個(gè)相關(guān)參數(shù)，都不能完成焊接。在這0.3s中，其溫升率基本不超過(guò)100℃／s，這說(shuō)明決定焊件能否順利完成焊接，其產(chǎn)熱過(guò)程在前0.3s內(nèi)的作用相對(duì)弱一些。如圖4為0.8s的各個(gè)截面的溫度圖，此時(shí)被焊兩工件的接觸面上的溫度已有少數(shù)點(diǎn)達(dá)到了甚至超過(guò)熔點(diǎn)溫度，從理論講這種情況有利于形成良好的接頭。由于整個(gè)接觸面上有足夠的熱量作用，不僅使得接觸面表層出現(xiàn)軟化，同時(shí)也使得表面內(nèi)的分子鏈排列方式由于熱的作用更易于改變。這時(shí)只需較低的外部壓力作用，即可使得已充分軟化甚至部分熔融的表層連接在一起。當(dāng)然這種連接的可靠程度，主要依靠軟化的程度，也就是說(shuō)取決于溫度的高低。
