摘要
成功的利用参数辨识的灵敏度法对防热涂层材料的热导率进行了参数估计。利用不同状态试验结果辨识的材料热导率对同类涂层材料是相同的或者接近相同,表明辨识的结果是可信的。把辨识的结果用于涂层材料热防护性能预测,与试验结果相符。
In this paper,the parameter identification of thermal conductivity coefficient for coating material is successfully completed using sensitivity method.The estimated results for different tests conditions are almost the same,indicating that the esti-mated results are rational.Using identification results of the thermal conductivity coefficient,the prediction results of thermal protection performance for coating material corresponds to the test results.
