热电偶动态响应特性对导热反问题辨识结果的影响

Effect of Thermocouple Dynamical Responsibility on Results Predicated by IHCP

通过引入一个简单的热电偶物理模型,研究了其动态响应特性对导热反问题辨识结果的影响.研究结果表明,由于动态响应误差的存在,使得表面温度和热流的辨识结果在大小上产生衰减,时间上产生滞后.热电偶时间常数越大,影响也越显著.

The effect of the dynamical Responsibility of a thermocouple on the predications ob- tained by inverse heat conduction analysis is studied in this paper.A simple thermocouple model is used to generate simulating data with dynamical error.It is demonstrated that the effect of the thermocouple's dynamical error is to diminish the magnitude of the predicated temperature and heat flux history and displace their distribution in time.
