摘要
采用Ansys有限元分析软件运用非线性分析的方法对Ag-Cu-Ti钎焊金刚石膜后的残余应力进行了数值模拟。在模拟中考虑了温度对材料性能的影响,计算了钎料对金刚石的热应力,并给出了钎料不同厚度情况下的残余应力。而后采用激光拉曼光谱对应力进行测量表明,有限元模拟结果与试验测试数据相吻合,相对误差不超过10%。
The thermal stress after the brazing of diamond film with Ag-Cu-Ti filler alloy is simulated by the nonlinear finite element analysis of ANSYS software. Considering the effect of temperature, the thermal stress from filler is calculated, and the thermal stress in different thickness of filler is given. Then the stress is tested with Laser Raman, and the results proved that the calculated stress in brazing is reasonable and the relative error between them was less than 10%.
