| 中文摘要: |
| 针对上海同步辐射装置(SSRF)光束线前端挡光元件需要承受高热负载的要求，对挡光元件所使用的纳米Al\-2O\-3颗粒增强Cu基复合材料Glidcop，采用一维稳态纵向热流法测量其在不同应变状态下的热传导系数。用有限元模拟了试件的温度场分布，并对试验结果进行了误差分析，揭示了试验误差的主要来源。试验测量结果表明，经历半寿命低周疲劳循环所产生的应变损伤累积对Glidcop导热系数的影响可以忽略。 |
| 英文摘要: |
| The components on the front end of synchrotron radiation beam line are usually used for absorbing high power density of synchrotron radiation. Shanghai Synchrotron Radiation Facility (SSRF), a third-generation synchrotron radiation light source，uses Al2O3-Cu composite material Glidcop to manufacture components on the front end. One-dimensional steady longitudinal heat flow method was used to study the thermal conductivity of Glidcop in different strain states. Test error was analyzed and a FEM simulation of specimen's temperature distribution was performed to reveal the error source. Test results show that the strain damage accumulation produced by half-life low-cycle fatigue loading does not have obvious effect on the thermal conductivity of Glidcop. |
