高温界面接触热阻试验
Interface contact resistance test under high temperature environment
摘要
Abstract
Thermal contact resistance between aircraft components is unavoidably.It is very important to acquire thermal contact resistance accurately for detailed design of thermal structure.To overcome the measurement difficulty under high temperature and high pressure,a measuring device was indepen-dently developed based on static heat flow method.The device can effectively obtain the thermal con-tact resistance between solid structures under given interface pressure and hot surface temperature up to 1 500℃.By using this device,three kinds of thermal contact resistance tests were carried out successfully.The influence law of pressure,temperature and interface roughness on the thermal contact resistance were figured out.Experimental results show that the measurement device is stable and reliable with uncompli-cated operation,while the simulation accuracy for temperature and pressure load is satisfied.This device can provide supports for the development and engineering application of aircraft thermal structures.关键词
