【摘要】：進入新世紀后,各式各樣的,國內(nèi)國外的商品隨著物流運輸?shù)绞澜绺鞯?物流的集散地各式各樣的包裹也是紛繁復雜,刺激了經(jīng)濟的發(fā)展,增加了物流的發(fā)展。選擇某品牌智能座便器的包裝系統(tǒng)為研究載體,通過Creo2.0、ANSYS workbench等軟件對外包裝和襯墊進行分析,對跌落結果進行分析,判斷包裝設計是否合理可靠。主要研究過程首先對緩沖包裝動力學理論研究進行整合,將一品牌智能座便器化為二自由度三次非線性系統(tǒng)。將陶瓷部分和易損的電子元件蓋部作為一個振動系統(tǒng),坐便器整體與與緩沖枕墊為一振動系統(tǒng),兩個單自由系統(tǒng)構成了二自由度系統(tǒng)。其次利用Creo2.0建立三維模型,導入ANSYS workbench中進行顯示動力學分析。設定跌落工況為二層堆碼處,進行面跌落,棱跌落,角跌落三種姿態(tài)的自由跌落仿真,從而分析包裝系統(tǒng)對坐便器的緩沖保護是否可靠。再次對材料屬性為EPE的下襯墊進行厚度上的參數(shù)優(yōu)化,實現(xiàn)厚度的尺寸減少,從而減少緩沖材料的使用。在角跌落過程中對于緩沖墊失效的問題進行了襯墊厚度增加的合理化建議。并重新建模仿真對結果進行了驗證。
[Abstract]:After entering the new century, various kinds of goods, domestic and foreign goods are transported to various parts of the world with the logistics, and the distribution center of logistics is also complicated, which stimulates the development of economy and increases the development of logistics. The packaging system of a brand of smart seat toilet is selected as the research carrier. The package design is analyzed by Creo2.0,ANSYS workbench and other software, and the drop result is analyzed to judge whether the package design is reasonable and reliable. In the main research process, the theory of cushioning packaging dynamics is integrated, and a brand of smart seat toilet is transformed into a two-degree-of-freedom cubic nonlinear system. The ceramic part and the vulnerable electronic component cover are regarded as a vibration system, the toilet and cushioning cushion are used as a vibration system, and two single free systems constitute a two-degree-of-freedom system. Secondly, the three-dimensional model is built by Creo2.0, and the display dynamics is analyzed by importing it into ANSYS workbench. The free drop simulation of surface drop, edge drop and angle drop is carried out to analyze whether the packaging system is reliable for the buffer protection of the toilet. Thirdly, the thickness parameters of the lower gasket with EPE property are optimized to reduce the size of the thickness and reduce the use of buffer material. In the process of angle drop, the reasonable suggestion of increasing the thickness of cushion is put forward for the failure of cushion. The results are verified by re-modeling and simulation.
