【摘要】：氣動(dòng)技術(shù)具有高速高效、低成本、清潔安全、易維護(hù)等優(yōu)點(diǎn)，廣泛應(yīng)用于工業(yè)生產(chǎn)中，是生產(chǎn)過程機(jī)械化和自動(dòng)化的有效手段之一。隨著傳感技術(shù)、通信技術(shù)的不斷發(fā)展，對(duì)氣動(dòng)系統(tǒng)低速運(yùn)行時(shí)的特性有了更高的要求。計(jì)算機(jī)仿真技術(shù)在科學(xué)研究、軍事、教育、工業(yè)、交通等領(lǐng)域已得到大量應(yīng)用，對(duì)氣動(dòng)系統(tǒng)仿真模型的建立及氣缸低速摩擦力特性的研究具有十分重要的意義。 利用氣體狀態(tài)方程和熱力學(xué)方程等推導(dǎo)出通用的氣體流量、溫度壓力的一階微分方程。從摩擦學(xué)的角度分析摩擦力和爬行機(jī)理，結(jié)合Stribeck效應(yīng)和Karnopp分段模型推導(dǎo)出氣缸摩擦力的數(shù)學(xué)模型，為建立氣動(dòng)元件和系統(tǒng)仿真模型奠定理論基礎(chǔ)。 以SMC的CEP1系列單桿雙作用氣缸和SMC的VQ100系列通直動(dòng)式開關(guān)閥為物理模型，在AMESim環(huán)境下建立相應(yīng)的元件仿真模型，并對(duì)氣動(dòng)仿真元件加以驗(yàn)證。充分利用AMESim在系統(tǒng)仿真建模簡(jiǎn)單、方便的長處，以及Matlab/Simulink數(shù)據(jù)處理能力方面的優(yōu)勢(shì)，將兩款軟件接口建立氣動(dòng)系統(tǒng)聯(lián)合仿真模型。通過對(duì)仿真結(jié)的對(duì)比分析，檢驗(yàn)Simulink中控制部分設(shè)計(jì)的合理性和可行性。 利用聯(lián)合仿真模型研究氣動(dòng)系統(tǒng)低速運(yùn)行時(shí)摩擦力特性，，觀察不同工作壓力、負(fù)載、缸徑的條件下氣缸速度波動(dòng)情況和響應(yīng)速度，來判斷氣缸爬行程度，總結(jié)氣缸摩擦力特性在工作壓力、負(fù)載和缸徑因素影響下的變化規(guī)律。
[Abstract]:Pneumatic technology has the advantages of high speed, high efficiency, low cost, clean and safe, easy to maintain and so on. It is widely used in industrial production and is one of the effective means of mechanization and automation of production process. With the continuous development of communication technology, the characteristics of pneumatic system running at low speed have higher requirements. Computer simulation technology has been widely used in scientific research, military, education, industry, transportation and other fields. It is of great significance to establish the simulation model of pneumatic system and to study the friction characteristics of cylinder at low speed. The general first order differential equations of gas flow rate and temperature and pressure are derived by using the gas state equation and thermodynamic equation. The friction force and creeping mechanism are analyzed from the angle of tribology. The mathematical model of cylinder friction is derived by combining the Stribeck effect and the Karnopp segment model, which lays a theoretical foundation for the establishment of pneumatic components and system simulation models. Based on the physical model of SMC CEP1 series single rod double acting cylinder and SMC VQ100 series straight-acting switch valve, the corresponding element simulation model is established in AMESim environment. And the pneumatic simulation components are verified. The advantages of AMESim in the system simulation modeling is simple and convenient, as well as the advantages of Matlab/Simulink data processing ability. The joint simulation model of pneumatic system is established by the two software interfaces, and the rationality and feasibility of the design of the control part in Simulink are verified by the comparison and analysis of the simulation results. The friction characteristics of pneumatic system at low speed are studied by using the combined simulation model, and the fluctuation and response speed of cylinder velocity under different working pressure, load and cylinder diameter are observed to judge the crawling degree of the cylinder. The variation law of cylinder friction characteristics under the influence of working pressure, load and cylinder diameter is summarized.
