【摘要】 通过对链式结构模型与多段特别是三段集总参数模型的精细比较，从模型的理论精度、仿真结果及计算量等方面对链式结构模型的优、缺点作了系统的分析。链式结构模型的计算量与三段集总模型一样，但是，链式结构模型的理论精度比三段集总模型要高出两阶，从仿真结果也可以看出链式结构的优越性。该文理论分析与仿真结果为链式结构模型在工程上的推广提供了有力的理论与实践依据更多还原

【Abstract】 Through the comparison between the chain structure model and the multi segment model based on lumped parameter, the advantages and disadvantages of the chain structure model were analyzed in this paper in terms of the theoretical precision, simulation results, and computation time. Although the computational time of both chain structure model and three segment model is same, the precision of chain structure model is two orders higher than that of the three segment model. In addition, it is easy to find from the simulation results that chain structure model has more advantages. Also, the comparison provides the theoretical and practical basis for the engineering application of the chain structure model.更多还原
