中文摘要:
      采用摩擦试验方法在模拟压气机环境下对TC4钛合金起燃温度和扩散燃烧条件进行了研究,采用有限元方法计算静子件摩擦生热引发燃烧过程温度及分布特征。结果表明,转子件碰磨环首先发生燃烧,但静子件热量累积是扩散燃烧的必要条件;首次获得TC4钛合金在模拟压气机环境下起燃温度为1266.47℃,与有限元模拟计算起燃温度1210℃误差为3.6%;当TC4钛合金静子件截面总加温面积达到25%,932℃~1210℃高温区域面积达到3.06%,静子件发生扩散燃烧。
The Ignition Temperature and Diffusion Combustion Conditions of Titanium Alloy under the Simulated Environment

英文摘要:
      The ignition temperature and the diffusion combustion conditions of TC4 titanium alloy were studied under the simulated compressor environment by the friction tests. The temperature and distribution characteristics of the combustion process were calculated by the finite element method. It was shown that rubbing rings of rotors were first burned, which dependedSon the heat accumulation of stators. For the first time, the ignition temperature(1266.47℃) of TC4 titanium alloy under the simulated compressor environment was obtained, and the error between the measured temperature and the ignition temperature(1210℃) calculated by the finite element method was just 3.6%. The stator began to burn when its total heating areas of cross section reached 25% and its areas of high temperature between 932℃ and 1210℃ were 3.06%.
