Research on Maintenance of Large-scale Equipment Based on Reliability
The large-scale equipment manufacturing enterprise has rigorous compartmentalization, forcible command, and its production organizing trait usually is high burst, multiple breeds, small batch, and high precision. Combined with dynamic and uncertainty of manufacture environment, workshop production management process takes on complexity and uniqueness.
Focus on the objectivity of risk existed in the large-scale equipment,the paper analyses the reason that risk produce,and expounds the superiority that disperse risk management organization apply to risk management of large-scale equipment.
Aiming at the request of timely fault diagnosis, the complexity and security in the course of maintaining large-scale equipment, the author researches application of multi-agent technology in field of remote fault diagnosis. This article introduces collectivity structure of diagnosis system of multi-agent, composition and cooperation of diagnosis agent, and founds model of multi-agent fault diagnosis of complicated equipments.
The maintaining of large-scale equipment is complicated,has high requirement in safety and timely fault diagnosis. To meet the requirements,we studied the application of multi-agent technology in the field of remote fault diagnosis. In this paper,the structure of multi-agent diagnosis system,composition and cooperation among diagnosis agents are presented,and models of multi-agent fault diagnosis for complex equipments are built.
HIGH END MANAGEMENT MODE OF LARGE EQUIPMENT MANUFACTURE ENTERPRISES
On the basis of RCM theory, the text brings forward a new flow of selecting maintenance mode to large equipment according to system reliability. the way consider equipment malfunction and system reliability factor to confirm maintenance programmer and mode.
Of all sophisticated manufacturing technologies,special attention should be given to green manufacturing,precision manufacturing,microelectronic manufacturing,bio-manufacturing,micro/nano-manufacturing,energy equipment manufacturing,heavy and large-sized equipment manufacturing,manufacturing automation,digital manufacturing and intelligent manufacturing.
Additional tests are often required from the technology support center of manufacturing companies to diagnose faults for large-scale equipment, although these tests are often expensive and involve some risks to equipment.
Several examples are given on the interpretation and application of ARC data to environments ranging from lab to plant-scale conditions including discussions concerning the similarities and dissimilarities between the ARC and large-scale equipment.
However, one concern is that the big projects with large-scale equipment investment may risk causing contamination in the Sea of Okhotsk.
The alloy is recommended for manufacturing large-size equipment to operate at up to 950°C for prolonged periods.
With the expansion of mechanical design models in CAD, the Model Base Management system(MBMS)bas become the key problem to CAD system. the cbjects and tasks of MBMS in CAD, the functions and structures and some critical technology of MBMS are introduced. The development prospects are mentioned.
This paper introduced the implementation of the Analytical Hierarchy proress for selecting X CT. The course can be analyzed quantitatively. It seems that the process has opened up fine prospects in valuable equipment of hospitals.
The photoelectric orientation system of large scale equipment is a complex integrative optic electromechanical system. In order to get a good simulation effect, the semi physical simulation scenario is adopted. The system scenario, high precision stepper motor subdivision control system, simulation system performance auto detecting and the multimedia technique used in the training and teaching are mainly introduced in this paper.
