Embodiment Construction

[0045] The present invention is described further now.

[0046] Step 1. Step 1, sensor deployment, initialization and information recording;

[0047] Deploy pressure and flow sensors in the hydraulic circuit of the radar lifting system, and deploy ultrasonic sensors at the end of the lifting system to measure the lifting height; when the radar is lifted every time, monitor the real-time pressure and real-time flow data of the radar during the lifting process, The real-time pressure and real-time flow data are averaged as the pressure value and flow value during the lift; when the radar lifts to the target position, record the radar lift height information and lift time;

[0048] The above data are all transmitted to the computer for storage and waiting for the next step of processing.

[0049] The basic structure of the radar hydraulic lifting system includes: fuel tank, motor, pump, pipeline, control valve, control system, lifting cylinder, locking cylinder, lifting mechanis...

Abstract

The invention discloses a dynamic identification method of a weak link of a radar lifting system based on an inverse analysis technology. The method comprises the steps of sensor allocation, initialization and information recording, SADT (Self Accelerating Decomposition Temperature) analysis of the radar lifting system, FMEA (Failure Mode and Effects Analysis) of the radar lifting system, DBN (Dynamic Bayesian Network) modeling of the radar lifting system, data analysis and weak link identification. The method provides guidance for daily maintenance of the radar lifting system, avoids blind maintenance and lowers the maintenance cost. The method has the prominent advantages that the reliable modeling realizes structural topology mapping from a complicated electromechanical hydraulic system to a Bayesian network; and the weak link identification realizes logical relation mapping from running state monitoring information to spare part reliability. The method can be popularized and used in the fields of reliability assessment and intelligent maintenance of engineering machinery.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a method for dynamically identifying weak links of a radar lifting system based on an inversion analysis technology. Background technique [0002] The radar lifting system is one of the important subsystems of the whole radar system. It is a typical electromechanical-hydraulic coupling system. Its reliability runs through the whole process of radar equipment development, production and use. Life cycle costs etc. have an important impact. If the reliability of the radar lifting system is not high, high-tech performance such as radar early warning and detection cannot be fully utilized, and repeated maintenance will inevitably increase costs, and may even delay fighters and endanger the completion of combat missions. Therefore, dynamically identifying the weak links of the radar lifting system and formulating a reasonable maintenance strategy are the keys to ensuring its...
