摘要
目的基于正交试验的方法,探究枕型空气衬垫的规格、初始充气压强、温度、压缩速率在准静态压缩试验下对其缓冲性能影响的主次关系,得到一组使衬垫缓冲性能优良稳定的试验变量和一种枕型空气衬垫的优选方法。方法采用正交试验的方法设计L9=(34)的正交试验,以枕型空气衬垫为研究对象进行准静态压缩试验,将试验结果归纳整理并进行极差分析和综合优选,判断所研究因素对枕型空气衬垫缓冲性能影响的主次关系,综合优选缓冲性能最优的枕型空气衬垫。结果通过极差分析,得到了影响枕型空气衬垫缓冲性能的主次因素,由主到次依次为枕型空气衬垫规格、初始充气压强、温度、压缩速率,继而结合试验的易操作性综合优选了枕型空气衬垫的规格为100 mm×150 mm,初始充气压强为5 kPa,温度为30℃,压缩速率为100 mm/min,确定了一组使衬垫缓冲性能优良稳定的试验因素。结论采用正交试验方法综合优选缓冲性能最优的枕型空气衬垫这一方法是可行的,结果也明确了4个试验变量对枕型空气衬垫缓冲性能影响的主次关系,这种思路能够为后续类似缓冲包装试验研究设计提供参考。
Static compression test is carried out on the basis of orthogonal test to study the influence of the specifica-tion,initial air pressure,temperature and compression rate of pillow-shaped air cushion on its cushioning performance,to explore the primary and secondary factors influencing its cushioning performance under static compression test.A set of test variables are obtained to make the cushioning performance of pillow-shaped air cushion good and stable,and an op-timal selection method for pillow-shaped air cushion is proposed.An orthogonal test table of L9=(34)is designed by means of orthogonal test,and then static compression test is carried out with pillow-shaped air cushion as the research object.The experimental results are summarized and sorted out,and range analysis is carried out on the basis of which synthetic optimization selection is carried out.The order of the influence of several factors to be studied on cushioning performance of pillow-shaped air cushion is arranged by this method,so as to select a pillow-shaped air cushion with sta-ble and excellent cushioning performance.Through the range analysis,the order of the factors that affect the cushioning performance of the pillow-shaped air cushion is obtained,from the main to the next,namely the specification of the pil-low-shaped air cushion,the initial gas pressure,the temperature and the compression rate.Then combined with the ease of operation of the test,the pillow-shaped air cushion has a specification of 100 mm×150 mm,an initial inflation pressure of 5 kPa,a temperature of 30℃,and a compression rate of 100 mm/min.Therefore,a set of test factors which make the pil-low-shaped air cushion good and stable are determined.The study shows that it is feasible to select the pillow-shaped air cushion with the best cushioning performance synthetically by orthogonal test method,the results also clarify the se-quence of the four test variables'influence on the cushioning performance of pillow-shaped air cushion,which can also provide reference for the subsequent similar cushioning packaging test and design.
