摘要
通过分析第一级高压涡轮转子(HPT-1)叶片现场故障数据,综合考虑影响HPT-1叶片寿命的因素、故障模式、维修情况等,建立三维数学模型,通过降维处理得出HPT-1叶片寿命分布柱状图,使用最小二乘法减少所拟合的威布尔寿命分布曲线与柱状图之间的误差。为处理现场数据提供一种切实可行的方法,且为航空公司维修管理部门安排HPT-1叶片维修操作提供依据,对减少飞机停机时间、提高航空公司运作效益有着重要的意义。
By analyzing HPT-1 blades field failure data, 3D mathematical model is built considering the factors affect blade life, such as failure mode and maintenance condition. HPT-1 blades life distribution histogram is obtained by dimensional reduction. The error is assumed between the histogram and the Weibull distribution curve assumed with least square method, which provides an available method for field data management and a proof for HPT-1 maintenance arrangement of aviation enterprise. It is of importance for reducing downtime, and improving operation efficiency for aviation enterprise.
