Abstract

The invention discloses a prediction method for residual life of a spinning frame, which comprises the following steps of: extracting key parameters influencing equipment degradation by analyzing real-time monitoring data of the spinning frame, and constructing a degradation indication quantity of the spinning frame by utilizing a weighted principal component analysis method; and then establishinga degradation model based on the Wiener process by utilizing the constructed degradation indication quantity, and predicting the remaining service life of the spinning frame. The service life of thespinning frame is predicted, and a new method is provided for better managing the service life and health of the spinning frame.

Description

technical field [0001] The invention relates to the field of mechanical equipment reliability, in particular to a method and system for predicting the remaining operating life of a spinning frame. Background technique [0002] As a key large-scale equipment in the spinning process, the spinning frame directly determines the quality of the yarn, fabric, and even the quality of the textile. Among them, the roller is an important part of the drafting and twisting mechanism of the spinning frame. have a great impact. Because the whole spinning process is in a working environment of high temperature, high humidity and strong electricity, the spinning frame is susceptible to the influence of temperature, humidity and electromagnetism, coupled with objective factors such as wear, vibration and fatigue of the spinning frame itself, resulting in roller failure. Deformation, resulting in performance degradation and failure of the spinning frame, and high frequency of yarn breakage, s...
