摘　　要：利用UG软件建立航空发动机高压涡轮盘有限元模型,并用ANSYS软件进行了网格划分。对构件各状态下的应力、温度场进行计算分析,从而确定危险部位。根据热强参数方程,计算高压涡轮盘在不同工作状态下的蠕变寿命,从而得到其蠕变寿命载荷谱。对高压涡轮盘蠕变寿命载荷谱进行提取,并以蠕变寿命消耗线性叠加原理为基础,对高压涡轮盘的蠕变寿命进行等效计算。研究结论为高压涡轮盘蠕变寿命预测提供了依据。The finite element model of higpressure turbine disc of aeroengine was established by using UG software,and it was plotted into grid with ANSYS software.The stress and temperature fields of the components in each state were calculated and analyzed,the most dangerous position was determined.On the basis of heat intensity parameter equation,the creep lives of highpressure turbine disc under different working conditions were calculated,and the load spectrum of its creep life was obtained.The creep life load spectrum of highpressure turbine disc was extracted,and the creep life of highpressure turbine disc was equivalent calculated based on the linear superposition principle of creep life consumption.The research results provide a basis for predicting the creep life of highpressure turbine disc.
