摘要

对计量活门的磨损量进行建模

进行了探索研究

考虑了3种计算磨损量的方法.基于某型航空发动机燃油控制装置的计量活门试验数据的计算

结果表明:采用灰色理论的基于时间序列的一阶微分方程模型可以较准确地计算出计量活门的磨损量

相对误差小于5%.对于燃油控制装置计量活门磨损寿命的预测具有实用意义

可以为燃油控制装置整体使用寿命的提供一定的依据.

Abstract

Given the complicated traditional abrasion computing process

the opposite direction to model the abrasion loss of the metering valve was studied. Three ways to compute the abrasion loss were found. The result of some model of the aero-engine fuel control unit's metering valve test data shows that

the model of the differential equation of first order based on the time series can accurately calculate the abrasion loss of the metering valve

with the relative error less than 5%. This had the practical meanings to the life prediction of abrasion in the fuel control unit metering valve

providing a basis for the useful life of the fuel control unit.
