摘要：为研究某型燃气轮机驱动压缩机组动力涡轮机匣是否满足强度储备要求，基于局部分析方法，考虑了温度载荷和气动载荷等特征因素，建立了动力涡轮的热固耦合模型，分析了动力涡轮机匣的变形、应力分布情况。研究结果表明：动力涡轮机匣最大应力379.6MPa，满足设计强度储备要求；而温度是影响动力涡轮机匣形变与应力的主要因素。 To study whether the power turbine casing of Gas-Engine Driven Compressor Set meets the requirements of strength reserve, based on the local analysis method,characteristic factors such as temperature load and pneumatic load are considered. A thermo-mechanical coupling model of the power turbine is established，and the deformation and stress distribution of the casing are analyzed.The research shows that the the maximum stress of the power turbine casing is 379.6 MPa and meets the requirements of design strength reserve. Temperature is the main factor affecting the deformation and stress of power turbine casing. |

To study whether the power turbine casing of Gas-Engine Driven Compressor Set meets the requirements of strength reserve, we establish a thermo-mechanical coupling model of the power turbine based on the local analysis method considering characteristic factors such as temperature and pneumatic load. The deformation and stress distribution of the casing are analyzed. The research result shows that the maximum stress of the power turbine casing is 379.6 MPa, meeting the requirements of design strength reserve. In addition, temperature is found to be the main factor affecting the deformation and stress of power turbine casing. 供参考 |
