Embodiment Construction

[0089] Below the embodiment procedure of the present invention is described in detail, as Figure 5 As shown, the routine of this embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following routine of embodiment. The implementation is mainly divided into the following steps:

[0090] Step 1: Life cycle determination of equipment components

[0091] Step 1.1: Life cycle division of equipment components

[0092] The life cycle index model is used to divide the life cycle of equipment components, and the life cycle index H is used to represent the life cycle division of equipment. When it is in the interval [1,0.9), [0.9,0.7), [0.7,0.5), [0.5,0.3), [0.3,0], it means that the life cycle of the device is "youth", "adulthood", "Middle age", "old age", "failure", and denoted as h 1 、h 2 、h 3 ...

Abstract

The invention discloses a calculation method for reliability of welding equipment based on dynamic fault correlation, and uses historical data of equipment to perform dynamic analysis on fault correlation of equipment components. The present invention considers the introduction of the concept of life cycle, first measures the life cycle of equipment components, and obtains the life cycle index of equipment components; then analyzes the correlation between the various components of equipment, and introduces the life cycle index into the correlation analysis of equipment component failures In , the dynamic fault correlation of the equipment components is obtained; finally, the comprehensive reliability of the equipment components is measured based on the dynamic fault correlation, and the overall reliability of the entire equipment is further obtained. The present invention obtains the dynamic fault correlation of the equipment components by introducing the life cycle index of the equipment components, so that the equipment reliability measurement scheme based on the dynamic fault correlation can more accurately evaluate the overall reliability of the welding equipment.

Description

technical field [0001] The patent of the present invention relates to a dynamic analysis of the fault correlation of equipment components by using historical data of equipment, and then measures the life cycle index of equipment components, and finally introduces the life cycle index of equipment components into the fault correlation analysis between equipment components , and finally a method to measure the overall reliability of the equipment on this basis. Background technique [0002] With the development of technology and the expansion of enterprises, the manufacturing site is gradually moving towards the direction of assembly line, and more and more enterprises adopt efficient assembly line for production activities. The excellent design, assembly process and processing method of the production line and its equipment are important guarantees for its own reliability. Various abnormalities may occur in the equipment of the production line during production activities, an...
