| 摘要: |
| 舰船热力系统因使用、故障、维修和保障的复杂性，通过建立数学模型的解析方法不能满足其RMS论证的需要，而基于最小设备清单的Monte Carlo仿真法也因组成设备存在性能退化而不适合作为系统的故障判据。文章利用基于热力模型确定的可行使用方案替代基于逻辑关系确定的最小设备清单，按照系统在部分设备故障后是否还具有可行使用方案来判别系统是否故障，设计了基于可行使用方案的舰船热力系统RMS仿真流程，在仿真流程改进的基础上编制了舰船热力系统RMS论证软件。算例验证表明，改进的流程能够在保证仿真精度的同时，具有较高的计算效率。 |

| Abstract: |
| Because of complexity related to operation, maintenance, support and malfunction of ship steam power system, establishing math analytical model cannot satisfy the RMS argumentation demand. Based on the minimal equipment listing, Monte Carlo simulation method is not fit for system failure criterion either. The current research utilized feasible using schemes based on thermal model instead of minimal equipment listing based on logic relation. According to whether there were feasible using schemes when system partial equipment faulted, the research designed ship thermal system RMS simulation flow based on feasible using schemes. The ship thermal system RMS software was programmed based on improved simulation flow. Calculation examples demonstrated that the improved flow can satisfy the simulation precision, and the calculation efficiency is also improved. |
