【摘要】：氣壓傳動技術(shù)具有安全、可靠、無污染、成本低等特點，所以廣泛應(yīng)用于工業(yè)自動化生產(chǎn)中。而作為氣動系統(tǒng)最基本的執(zhí)行元件，氣缸同樣應(yīng)用場合廣泛，所以對氣缸的疲勞破壞、疲勞壽命等研究意義重大。本文選用日本SMC公司的MBF/L32-250系列標準氣缸作為研究對象，以該氣缸的疲勞破壞試驗為研究課題，從疲勞破壞理論和試驗系統(tǒng)設(shè)計兩個方面入手，對氣缸疲勞破壞模式、原因和特點進行研究，并由此進行氣缸疲勞破壞試驗系統(tǒng)設(shè)計研究。 本文首先從疲勞破壞特征和疲勞破壞機制兩方面論述了疲勞破壞理論，其中包括一些基本概念以及相關(guān)領(lǐng)域國內(nèi)外情況和發(fā)展水平。接著以課題所用試驗氣缸為例學習認識氣缸的構(gòu)造、分類和特性，并通過疲勞破壞理論的學習結(jié)合對試驗氣缸的認識，研究分析氣缸的疲勞破壞特點和原因，并確定氣缸疲勞破壞模式，為制定試驗方案做理論鋪墊。 根據(jù)氣缸疲勞破壞理論分析和具體試驗要求，本文確定是疲勞破壞試驗方法，并據(jù)此開展試驗設(shè)計，在確定疲勞破壞試驗方案時對頻率、負載、速度等重點試驗因素進行了特性分析，并使用相關(guān)仿真軟件對試驗因素特性進行仿真說明。然后，本文以氣動試驗國際標準ISO19973-3為指導進行試驗系統(tǒng)設(shè)計，，具體包括從安裝、減震、固定角度考慮設(shè)計的組裝式氣缸試驗平臺、能為氣缸提供穩(wěn)定、潔凈壓縮空氣的氣動系統(tǒng)設(shè)計以及可安全、方便、可靠控制氣缸運行和測試的電氣控制系統(tǒng)設(shè)計等三方面，旨在為氣缸疲勞破壞試驗提供安全、準確的運行環(huán)境和測試條件。 完成試驗系統(tǒng)設(shè)計后，本文選用相應(yīng)的儀器儀表并通過設(shè)計的試驗數(shù)據(jù)采集方法實現(xiàn)對相關(guān)氣缸試驗數(shù)據(jù)的準確采集，從而可以掌握整個氣缸壽命過程的數(shù)據(jù)變化情況，為后續(xù)試驗處理提供數(shù)據(jù)支持。最后，對試驗數(shù)據(jù)進行分類說明，并提出了一種可行的數(shù)據(jù)處理方法，可以簡單有效的分析氣缸疲勞破壞試驗數(shù)據(jù)。
[Abstract]:Pneumatic transmission technology has the characteristics of safety, reliability, no pollution, low cost and so on, so it is widely used in industrial automation production. As the most basic actuator of pneumatic system, cylinder is also widely used. Therefore, it is of great significance to study the fatigue failure and fatigue life of cylinder. In this paper, the MBF/L32-250 series standard cylinder of SMC Company of Japan is chosen as the research object. Taking the fatigue failure test of the cylinder as the research subject, the fatigue failure mode, causes and characteristics of the cylinder are studied from the two aspects of fatigue failure theory and test system design. The fatigue failure test system of cylinder is designed and studied. This paper first discusses the fatigue failure theory from the fatigue failure characteristics and fatigue failure mechanism. It includes some basic concepts as well as the domestic and foreign situation and the level of development in the related fields. Then take the experimental cylinder used in the subject as an example to learn about the construction classification and characteristics of the cylinder. Through the study of fatigue failure theory and the understanding of test cylinder, the characteristics and causes of cylinder fatigue failure are studied and analyzed, and the fatigue failure mode of cylinder is determined. According to the theoretical analysis of cylinder fatigue failure and the specific test requirements, this paper determines the fatigue failure test method, and carries out the test design accordingly, when determining the fatigue failure test plan, the frequency, load. The characteristics of the key test factors such as speed are analyzed and the simulation software is used to illustrate the characteristics of the test factors. In this paper, the design of the test system is conducted under the guidance of the international standard ISO19973-3 for pneumatic test, including the design of the assembled cylinder test platform from the angle of installation, shock absorption and fixation. It can provide stable, clean compressed air pneumatic system design and the design of electrical control system which can safely, conveniently and reliably control the cylinder operation and test. The purpose is to provide safe and accurate operating environment and test conditions for cylinder fatigue failure test. After the design of the test system, this paper selects the corresponding instruments and instruments, and through the design of the test data acquisition method to achieve the accurate collection of relevant cylinder test data. Thus we can master the data change of the whole cylinder life process, and provide data support for the subsequent test processing. Finally, the test data are classified and explained, and a feasible data processing method is proposed. The test data of cylinder fatigue failure can be analyzed simply and effectively.
