PDC刀具高频感应钎焊温度计算与试验
|
摘要
基于磁–热双向耦合理论,采用COMSOL Multi-physics建立三维非线性聚晶金刚石复合片(PDC)刀具高频感应钎焊温度场模型,计算高频感应钎焊时PDC钎焊处的温度场分布情况,设计所建模型的高频感应钎焊试验进行验证,分析钎焊处的温度变化规律。计算结果表明:在钎焊处温度达700℃之前,其升温变化规律近似线性,加热升温12 s左右即可达到钎焊有效温度;在钎焊有效温度区间内,试验中测得的钎焊处实际温度值与计算值的误差小于5%,可以此模型为基础确定钎焊参数。
Based on the theory of magnetic-thermal bidirectional coupling, the 3 D nonlinear high-frequency induction brazing temperature field model of the polycrystalline diamond compact(PDC) tool is established with COMSOL Multi-physics software. The PDC temperature field of high-frequency induction brazing is calculated and then verified by experiment designed in accordance with the model to analyze the law of temperature change at brazing position. The results show that the variation of PDC brazing temperature is approximately linear before it reaches 700 ℃. The effective temperature of the brazing can be reached when the PDC is heated for about 12 s. Within the effective temperature range of brazing, the error between the actual temperature value of brazing position measured in the experiment and the caculated is less than 5%. The brazing parameters can be determined on the basis of this model.
