Abstract

Purpose Hydraulic slide valve failure often results from competing failure modes, termed competitive failure. To enhance prediction accuracy for hydraulic slide valve remaining useful life, the authors propose a method incorporating competitive failure and Monte Carlo simulation. This method allows for more accurate prediction of hydraulic slide valve remaining useful life. Design/methodology/approach In this paper, the competitive failure mode of the hydraulic slide valve is analyzed by studying the two failure modes of the hydraulic slide valve, and the prediction of the remaining useful life of the hydraulic slide valve is studied by using the sample set generated by Monte Carlo simulation and the competitive failure joint model. Findings The results show that the proposed prediction method based on competitive failure and Monte Carlo simulation is more accurate than the traditional Bayesian joint model prediction method when dealing with the failure mode competition phenomenon of hydraulic slide valve. Originality/value In this paper, the remaining useful life prediction of hydraulic slide valve with competitive failure characteristics is studied, which provides a new idea for the remaining useful life prediction method.

基于退化-竞争失效共享随机效应识别的液压滑阀剩余使用寿命预测方法研究

目的液压滑阀故障通常是由相互竞争的故障模式造成的，称为竞争性故障。为了提高液压滑阀剩余使用寿命的预测精度，作者提出了一种结合竞争性故障和蒙特卡罗模拟的方法。本文通过研究液压滑阀的两种失效模式，分析了液压滑阀的竞争失效模式，并利用蒙特卡罗模拟生成的样本集和竞争失效联合模型，研究了液压滑阀剩余使用寿命的预测。结果表明，在处理液压滑阀的失效模式竞争现象时，所提出的基于竞争失效和蒙特卡罗仿真的预测方法比传统的贝叶斯联合模型预测方法更准确。原创性/价值本文研究了具有竞争失效特征的液压滑阀的剩余使用寿命预测，为剩余使用寿命预测方法提供了一种新思路。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-11-2023-0361/。
