摘　　要：综合运用刚度等效原理、质量等效原理等思想将水平杆处理成等效连续介质模型。在该模型的基础上运用有限段离散时间传递矩阵法对水平杆进行动力学计算,计算结果与试验结果基本吻合,验证了等效模型的实用性和有限段离散时间传递矩阵法在水平杆动力学分析中的可行性。Continuum method based on rigidity equivalent principle, mass equivalent principle and concentrated parameter principle was used to transform the horizontal bar to a continuous medium model. The dynamic characteristics of pendulum system of some launching tower were calculated by using finite-segment transfer-matrix-method（FS-DT-TMM）.The results from calculation tally with the test well. It is proved that the equivalent model to be valid and the calculation by FS-DT-TMM be feasible.
