| 摘 要： | 采用高热负荷实验并结合有限元计算考察和分析了热流密度对钨铜合金工作应力分布的影响。结果表明：钨铜材料作为过渡层可以降低工作应力,当热流密度为1 MW/m2时,在钨板与铜块间焊接W60Cu合金作为过渡层,可使最大应力值比没有过渡层降低36%左右;工作时最大应力出现在两侧焊接层附近,并随热流密度增大而增大;钨铜合金（W60Cu）作为过渡层的试样在两焊缝处的应力,上部焊缝应力较大,下部焊缝应力较小。

| Abstract: | The effect of heat flux density on thermal stress distribution of W/Cu material was investigated and analyzed via cyclic high heat load experiment and finite element analysis, It was found that working stress could be reduced under the condition of W/Cu material as the transition layer. The maximal stress in the sample with W60Cu as the transition layer was about 36% lower than one without transition layer under heat flux of 1 MW/m2. In addition, the maximal stress was nearby the two welding layer, and it increased with increase of heat flux. For the stress of W/Cu alloy （W60Cu） as the transition layer at two welded joints, upper was larger than lower. |
