【摘要】 该文提出了一种用于动态过程集总参数模型的新的快速求解法,并将其应用于锅炉中单相工质汽温动态过程的集总参数模型。该方法首先对模型进行变量分析与综合,并寻求微分方程的精确解与各个变量之间的函数关系;然后求解该模型时不再直接求解微分方程(组),而是通过前面得到模型精确解与各变量之间的函数关系进行计算。实例计算表明,该方法的计算结果与隐式算法误差小,且计算速度有较大提高。更多还原

【Abstract】 A new fast solution method for lumped parameter dynamic model is put forward, and is applied to lumped parameter dynamic model for single-phase temperature in boiler. In this method, variables of the model are analyzed and synthesized firstly, and relations between the precise solution and variables of the model are found. Then the model is calculated by the relations, not be solved directly any longer. An example indicates that error between results of the new method and precision solution is little and calculation speed is improved obviously.更多还原
