【摘要】：設備在使用現(xiàn)場能否安全可靠運行，不僅關(guān)系到用戶的經(jīng)濟利益，同時也是設備質(zhì)量的最終體現(xiàn)。設備的現(xiàn)場可靠性反映了設備從設計、制造、運輸?shù)绞褂萌^程的信息，因此改進設備的現(xiàn)場可靠性，是全面提升設備可靠性的重要途徑。本文主要對改進設備現(xiàn)場可靠性的問題進行初步的研究。 目前在改進現(xiàn)場可靠性研究方面，主要是解決設備局部的改進問題，缺少改進設備現(xiàn)場可靠性完整且系統(tǒng)的方法。本文在先進可靠性分析技術(shù)的基礎上，總結(jié)了一套改進現(xiàn)場可靠性的分析方法和技術(shù)路線。隨后結(jié)合某國產(chǎn)抱罐車與某進口抱罐車的現(xiàn)場使用數(shù)據(jù)，按照所提出的技術(shù)路線進行如下分析： 1)根據(jù)設備的性質(zhì)及數(shù)據(jù)的完整性，選取合適的評價指標，對抱罐車現(xiàn)場可 靠性進行定量的分析。 2)采用故障模式、影響和危害性分析（FMECA）技術(shù)，找出各自現(xiàn)場可 靠性的薄弱環(huán)節(jié)。 3)利用非參估計方法計算失效發(fā)生率，明確抱罐車及各子系統(tǒng)的失效型式。 4)分析氣候因素對抱罐車現(xiàn)場可靠性的影響，并給出對現(xiàn)場可靠性影響的最優(yōu)點。 5)根據(jù)以上的對比分析，從制造商與用戶的角度出發(fā)，給出國產(chǎn)抱罐車的現(xiàn)場可靠性改進建議。 通過對抱罐車實際的案例分析，，驗證了現(xiàn)場可靠性改進技術(shù)路線的可行性。
[Abstract]:Whether the equipment can run safely and reliably on the site is not only related to the economic benefit of the user, but also the ultimate embodiment of the equipment quality. The field reliability of the equipment reflects the information from the design, manufacture, transportation to the use of the whole process. Therefore, improving the field reliability of the equipment is an important way to improve the reliability of the equipment. In this paper, the problem of improving the reliability of equipment on the spot is studied. At present, in the research of improving the field reliability, it is mainly to solve the problem of local improvement of equipment, but there is no method to improve the integrity and system of the field reliability of the equipment. On the basis of advanced reliability analysis technology, this paper summarizes a set of analysis methods and technical route to improve field reliability. Then combined with the field usage data of a domestic tank truck and an imported tank truck, the following analysis is carried out according to the proposed technical route: 1) according to the nature of the equipment and the integrity of the data, the appropriate evaluation index is selected. Quantitative analysis of locale availability of tank truck is carried out. 2) adopt the fault mode, influence and harmfulness analysis (FMECA) technology, find out the weak link of their respective locale dependability. 3) the failure rate is calculated by non-parametric estimation method, and the failure types of tank truck and subsystems are determined. 4) the influence of climate factors on the field reliability of tank truck is analyzed, and the most advantages of the effect on the field reliability are given. 5) according to the above comparative analysis and from the point of view of the manufacturer and the user, the suggestions for improving the field reliability of the domestic truck are given. The feasibility of improving technical route of field reliability is verified by analyzing actual cases of tank truck.
