Abstract

The invention discloses an evaluation method for robustness for a natural gas pipeline valve, pertaining to the field of reliability tests and data analyses of mechanical equipment. The evaluation method for robustness for the natural gas pipeline valve has the following steps: (1) obtaining environmental factors affecting fault frequency of the natural gas pipeline valve and the change range corresponding to the environmental factors based on operation data of the natural gas pipeline valve; (2) normalizing values of different environmental factors based on the change range corresponding to the environmental factors to obtain the normalized data range of different environmental factors; (3) testing values of different environmental factors based on the normalized data range of environmental factors and obtaining robustness of the natural gas pipeline valve under the effect of single environment factor; (4) obtaining weight of the different environmental factors in robustness for the natural gas pipeline valve; (5) obtaining robustness for the natural gas pipeline valve through robustness for the natural gas pipeline valve and weight of different environmental factors based on effect of the different environmental factors.

Description

technical field [0001] The invention relates to the field of mechanical equipment reliability test and data analysis, in particular to a robustness evaluation method for natural gas pipeline valves. Background technique [0002] Robustness refers to the ability of the system to maintain its function or property under the condition of external disturbance. At present, most researches on robustness focus on network systems. For example, Qiao Jinsuo et al. (Qiao Jinsuo, Wang Xifu, Shen Xisheng, etc. Coal transportation network structure robustness evaluation and application research [J]. Transportation System Engineering and Information, 2013, 13(4): 126-133) used the coal transportation network The robustness of the coal transportation network is studied by the variation of the transportation distance after the disturbance. Cheng Ling (Cheng Ling. Robust Supply Chain Network Design Considering Facility Damage [D]. Xi'an: Chang'an University, 2013.) Researched the robustness ...
