包装件缓冲特性的有限元仿真可靠性分析

目的研究计算机有限元仿真在缓冲包装研发环节的可靠性。方法利用计算机仿真进行缓冲包装研发,能够较全面地提供所需参数,缩短开发周期,但计算机仿真的可靠性有待进一步验证。通过Ansys Workbench对智能灯泡包装件的缓冲特性进行仿真分析,主要分析包装衬垫的加速度响应,并结合传统的振动与跌落试验进行对比。结果振动、跌落的仿真结果与真实试验的结果误差分别为9%和15.91%,排除客观存在的误差,两者差异在可接受范围内。结论验证了有限元仿真方法在缓冲包装研发环节的可靠性,可为传统的包装研发环节提供新方法。

Finite Element Simulation Reliability of Package Cushioning Characteristics

The work aims to study the reliability of computer finite element simulation in the research and development of cushioning packaging. Computer simulation could be used for cushioning packaging R&D, which could comprehensively provide the required parameters and shorten the development cycle. However, the reliability of computer simulation should be further verified. The cushioning characteristics of intelligent bulb packages were simulated by Ansys Workbench, mainly analyzing the acceleration response of the packaging liner and making comparison combined with the traditional vibration and drop test. The errors of the simulation result of vibration and drop test and the real test result were respectively 9% and 15.91%. Except the objective errors, the difference of the both was within the acceptable range. The study verifies the reliability of finite element simulation method during cushioning packaging research and development. The study can provide a new method for traditional packaging R&D.
