【摘要】：充氣袋包裝特指通用氣墊基于特定產(chǎn)品進(jìn)行熱封成型的特殊緩沖包裝形式，課題探討了包裝的基本構(gòu)成與特性，并分析了影響其緩沖性能的各方面因素；通過對(duì)影響包裝效果的各方面因素分析，找出其影響規(guī)律，并以瓶裝產(chǎn)品的充氣袋包裝為基礎(chǔ)，為其包裝設(shè)計(jì)提供理論基礎(chǔ)與指導(dǎo)，使充氣袋緩沖包裝設(shè)計(jì)更合理、可靠。 首先考慮到在包裝系統(tǒng)的評(píng)估試驗(yàn)中，跌落造成的沖擊最為劇烈，課題通過跌落沖擊試驗(yàn)與力學(xué)模型分析的方法評(píng)估氣墊的緩沖效果；通過跌落試驗(yàn)結(jié)果與力學(xué)模型分析來了解氣墊在跌落過程中的行為，從而評(píng)估不同規(guī)格氣墊對(duì)跌落沖擊過程的影響，得到不同充氣壓力、不同氣室寬度與不同跌落高度所帶來的緩沖效果。將沖擊過程中的能量損失考慮到包裝系統(tǒng)中簡化數(shù)值分析。研究表明跌落過程能量損失對(duì)分析結(jié)果有很大影響。 其次，通過對(duì)充氣袋基本單元、不同規(guī)格的氣墊進(jìn)行相關(guān)力學(xué)性能的試驗(yàn)測試，即對(duì)空氣墊進(jìn)行了靜態(tài)壓縮試驗(yàn)，得到不同規(guī)格氣墊的應(yīng)力-應(yīng)變曲線，并從中得到不同薄膜厚度、初始?xì)鈮号c氣室寬度對(duì)其壓縮特性與緩沖特性的影響；針對(duì)不同規(guī)格氣墊，在一定包覆面積下，選用不同重塊質(zhì)量，進(jìn)行模擬跌落試驗(yàn)，從而了解不同薄膜厚度、初始?xì)鈮�、氣室寬度等因素�?duì)緩沖性能的影響。在以上試驗(yàn)的基礎(chǔ)上，利用靜態(tài)壓縮試驗(yàn)得到的應(yīng)力-應(yīng)變曲線，，采用能量法，對(duì)跌落沖擊試驗(yàn)過程進(jìn)行力學(xué)模型分析，加入能量損失的探討，利用試驗(yàn)結(jié)果與數(shù)值模擬的值歸納出不同靜應(yīng)力下，不同氣室寬氣墊的能量損失選用標(biāo)準(zhǔn)；由此預(yù)測跌落沖擊試驗(yàn)過程中的最大加速度值，結(jié)果顯示與試驗(yàn)值相近，因而可以利用數(shù)值模擬方法代替跌落沖擊試驗(yàn)預(yù)測最大加速度值。 通過上述力學(xué)模型分析的方法，對(duì)充氣袋的氣墊規(guī)格參數(shù)設(shè)計(jì)提供了理論依據(jù)；再根據(jù)傳統(tǒng)設(shè)計(jì)六步法，擬定瓶裝產(chǎn)品的充氣袋包裝設(shè)計(jì)方法，并提出了氣墊規(guī)格參數(shù)的設(shè)計(jì)流程圖。進(jìn)一步根據(jù)各因素對(duì)氣墊特性的影響規(guī)律，對(duì)葡萄酒瓶裝產(chǎn)品進(jìn)行充氣袋包裝設(shè)計(jì)與尺寸參數(shù)確定，并通過跌落試驗(yàn)驗(yàn)證了其設(shè)計(jì)的可行。
[Abstract]:The inflatable bag packaging refers to the special cushioning packaging form in which the general air cushion is formed by heat sealing based on specific products. The basic structure and characteristics of the packaging are discussed, and the factors affecting its cushioning performance are analyzed. Through the analysis of various factors affecting the packaging effect, the influence law is found out, and based on the inflatable bag packaging of bottled products, the theoretical basis and guidance are provided for the packaging design, so that the cushion packaging design of the inflatable bag is more reasonable and reliable. Firstly, considering that the impact caused by drop is the most severe in the evaluation test of packaging system, the cushioning effect of air cushion is evaluated by drop impact test and mechanical model analysis. The behavior of air cushion in the process of falling is understood by the result of drop test and the analysis of mechanical model, and the influence of air cushion of different specifications on the process of falling impact is evaluated, and the different inflatable pressure is obtained. The buffer effect of different air chamber width and different drop height. The energy loss during impact is taken into account in simplified numerical analysis in packaging system. The results show that the energy loss of the drop process has a great influence on the analysis results. Secondly, the stress-strain curves of air cushion with different specifications are obtained by testing the mechanical properties of the basic unit and different specifications of the air cushion, that is, the static compression test of the air cushion. The effects of different film thickness, initial pressure and chamber width on its compression and buffer characteristics were obtained. According to different specifications of air cushion, under a certain covering area, different weight mass was selected to carry out simulated drop test, so as to understand the effects of different film thickness, initial air pressure and air chamber width on the buffer performance. On the basis of the above tests, the stress-strain curve obtained from static compression test is used to analyze the mechanical model of drop impact test process by energy method, and the energy loss is discussed. According to the experimental results and numerical simulation values, the energy loss criteria of different chamber wide gaskets under different static stresses are concluded. The results show that the maximum acceleration value in drop impact test can be predicted by numerical simulation instead of drop impact test. The theoretical basis for the design of the air cushion specification parameters of the inflatable bag is provided by the above method of mechanical model analysis. According to the traditional six-step design method, the packaging design method of air-filled bag for bottled products is worked out, and the design flow chart of air cushion specification parameters is put forward. Furthermore, according to the influence of various factors on the air cushion characteristics, the packaging design and dimension parameters of the wine bottle were determined, and the feasibility of the design was verified by drop test.
