摘　　要：考虑船舶核动力装置冷凝器结构特点和工作原理 ,建立了一个新型合理完善的船舶核动力装置冷凝器动态特性分析数学模型 ,并运用Runge-Kutta法对此模型求解 .研制了用于船舶核动力装置冷凝器稳定运行及扰动和事故工况下动态数值模拟的分析程序 .在几种扰动工况下对冷凝器动态特性进行了计算与分析 ,计算结果与理论分析相符 .A new reasonably perfect numerical model has been established with necessary consideration accorded the structural features and operating principle of the condenser for shipborne nuclear power unit for analysis of dynamic characteristics of a condenser for shipborne nuclear power unit,and this model has been solved by the Runge_Kutta method.Analysis programs have been developed for dynamic numerical simulation under the conditions of steady operation,disturbance,and accident.The dynamic characteristics of condenser has been calculated and analysed under several disturbances,and the results of calculation are in good agreement with the theoretical analysis.
