| 摘 要： | 针对低散热发动机存在的热负荷状况,分析了非稳态导热有限元计算的特点:运用经验公式求出了发动机燃烧室部件燃气侧的传热边界条件;运用有限元法对隔热部件进行了热强度分析。计算结果表明:热负荷和热应力增大是造成隔热件可靠性降低的主要因素之一。

| Abstract: | This article analyses the character of the finite element method in unstable heat transmission. The heat transmission boundary conditions of the firebox' combustion gas are computed by experience formula. The hot intensity of the heat insulation parts is analysed by the finite element method. The results indicate that the accretion of the hot burden and the hot intensity is one of the main reasons to lower the security of the hot insulate parts. |
