摘要
对螺旋压力机打击力测量不准的原因进行了研究，得出了一些初步性的结论，建立了打击力测量的力学模型，并用实验作了定性验证．最后对打击力测量中存在的问题做了探讨．
Studies the reason of unaccountable measuring blow force in screw press.The primary conclusion was made.A kind of dynamic model of measuring blow force was established.The qualitative conclusion was approved by experiments.At last,some problems on measuring blow force was put forwards.
