摘要
基于激光高能快速加热和多点温度计算机自动采集技术 ,以一维不稳定导热模型为核心 ,设计了金属材料导热系数的实验测量方案 ,并实测了 3 0 4不锈钢的导热系数 ,测试结果具有较高的工程精度。
Based on the laser high-energy and rapid heating,and the technology of multicast temperature computer dada acquisition,the experimental procedure for measuring metal material heat conductivity was designed based on the one-dimensional unstable heat transfer model. The heat conductivity of 304 stainless steel was obtained,and then compared with the theoretical value. Results show that the experimental value agree well with the theoretical value. The above procedure is feasible and the results are quite accurate to meet the engineering requirment.
