摘要: 采用彈塑性大變形熱力耦合有限元法研究了鋁板溫軋過程，側重計算軋件厚向溫度分布，并分析了接觸熱傳導系數、軋件熱物性參數（導熱系數、比熱、密度）對計算結果的影響，計算結果與實驗結果比較吻合Abstract: The warm rolling of aluminum plate was studied with the aid of elastic-plastic and thermal-mechanical coupled FEM, particular attention was paid to predict the temperature distribution through the backness of rolled plate.The influences of contact heat transfer, coefficient heat material data (thermal conductivity, heat capability, density) on calculated result were analyzed. Comparison of the calculated results with those from experiment show good agreement.
