摘要
针对50 t双柱液压机拉杆磨损的问题,建立了液压机机身的有限元模型,通过有限元分析确定了拉杆弯曲变形和拉杆磨损的主要原因。依据机身变形特点,对上横梁结构进行了加强,并对优化后的机身进行了有限元分析与验证试验。结果表明:经过结构优化,中心加载条件下拉杆最大变形量减小至0.222 mm,偏载条件下拉杆最大变形量减小至0.526 mm,液压机运行平稳,有效解决了拉杆的磨损问题。
To avoid columns wear,finite element model of the 50 t double-column hydraulic press frame was established.Through the finite element analysis,it is determined the main reason for the columns bending and wearing.According to deformation analysis,the upper beam was strengthened and optimized.Numerical simulations and experiments were carried out to verify the rigidity of the hydraulic press frame.The results show that under the condition of central load and partial load,the maximum deformation of columns are reduced to 0.222 mm and 0.526 mm,respectively.The press runs well and no wear on the columns.
