| 目的 针对市面上不同薄膜厚度的充气垫进行跌落试验和仿真分析，得出薄膜厚度对充气垫的缓冲性能影响规律，为充气垫缓冲材料的选择与使用提供理论依据。方法 应用柱状充气垫做玻璃保温杯的缓冲包装，测试跌落试验过程加速度变化情况，并将跌落测试结果与仿真分析结果做对比分析。 结果 当跌落高度为40 cm时，采用薄膜厚度分别为55，60，65 μm的充气垫，玻璃杯最大响应加速度依次为246，283，322 m/s2;当跌落高度为60 cm时，玻璃杯最大响应加速度依次为357，419，452 m/s2;当跌落高度为80 cm时，玻璃杯最大响应加速度依次为569，693，751 m/s2。以薄膜厚度为55 μm的充气垫为例，模拟跌落高度为40，60，80 cm时，玻璃杯最大响应加速度依次为268，399，631 m/s2。结论 薄膜厚度在一定程度上影响着充气垫的缓冲性能，在一定范围内，充气垫的薄膜厚度越小缓冲性能越佳。同时仿真试验所得结论符合误差要求，可为充气垫缓冲材料的进一步研究提供理论支撑。 |

| According to the drop test and simulation analysis of inflatable cushion with different film thicknesses in the market, the influence law of film thickness on cushioning performance of inflatable cushion is obtained to provide a theoretical basis for the selection and use of cushioning materials of inflatable cushion. Cylindrical inflatable cushions have been used as buffer packaging for glass thermos cups to test the acceleration changes during the drop test. The drop test results have been compared with the simulation analysis results. When the drop height is 40 cm, the inflatable cushions with film thicknesses of 55, 60, and 65 μm are used, and the maximum response acceleration of the glass is 246, 283, and 322 m/s2respectively; when the drop height is 60 cm, the maximum response acceleration of the glass is 357, 419, and 452 m/s2respectively; when the drop height is 80 cm, the maximum response acceleration of the glass is 569, 69, and 751 m/s2respectively. Taking the inflatable cushion with a film thickness of 55 μm as an example, when the simulated drop height is 40, 60, and 80 cm respectively, the maximum response acceleration of the glass is 268, 399, and 631 m/s2respectively. The film thickness affects the cushioning performance of inflatable cushion to a certain extent. In a certain range, the smaller the film thickness of inflatable cushion, the better the cushioning performance. At the same time, the simulation results meet the error requirements, which can provide theoretical support for further research of inflatable cushion cushioning materials. |
