    三輥連軋管機剛度分析研究

    Analysis of Rigidity of 3-roll Mandrel Pipe Mill

    • 摘要: 利用接觸力學、材料力學等相關知識，對三輥連軋管機的剛度進行理論解析計算，得出各部件的剛度計算解析公式；使用有限元軟件，對某一規(guī)格連軋管機的各子部件進行剛度驗算，逐一驗證各子部件的剛度計算公式；利用解析計算匯總得出某一規(guī)格連軋管機的綜合剛度，并在現(xiàn)場對該連軋管機的剛度進行測試。分析結果表明：子部件剛度計算解析公式的準確性較高；現(xiàn)場實測綜合結果與解析公式計算結果較為接近，誤差在5%以內。有限元分析及現(xiàn)場實測兩種方法驗證了解析公式具有可靠性。

       

      Abstract: Analytical calculation of the rigidity of the 3-roll mandrel pipe mill is theoretically conducted with related knowledge concerning contact mechanics and material mechanics to deduce the calculation formulas for rigidities of different components of the mill.The rigidity of each individual component of a certain type mandrel mill is verified with relevant FEA software，and in this way the rigidity calculation formula for each component is verified，too.Based on the summary of the rigidity calculations，the overall rigidity of the mill is found out，and then the rigidity of the mill is tested on the site.The analysis result shows that the said analytical calculation formula for the component rigidity of the mill can bring about rather high accuracy；the overall rigidity as obtained via the on-the-site testing is close to the calculation result via the analytical formula，and the error is just within 5%.The results from the verifications with both the FEA software and the on-the-site testing method have proven the reliability of the above mentioned analytical formulas.
