摘　　要：搅拌系统是卧式搅拌磨机的主要组成部分,其性能优劣直接影响着卧式搅拌磨机的性能。通过建立搅拌系统的有限元模型,对其进行模态和不平衡响应分析,根据模态分析结果,计算出搅拌系统的临界转速,验证了搅拌系统结构的合理性。采用试验法对搅拌系统进行了不平衡响应分析,预测了其不平衡振动特性,为调节其动平衡,提高卧式搅拌磨机的稳定性,提供了参考依据。Mixing system is the main part of the horizontal stirring mill,whose performance can directly affect the per-formance of mill.Modal analysis and unbalance response analysis were carried out by establishing the finite element model of mixing system.The critical rotating speed of stirring system was achieved based on the modal analysis results and the stir-ring system structure was verified.It provided the basis for adj usting the mixing system and improved the stability of the mill by using the test method for unbalance response analysis to predict the unbalance vibration characteristics.
