Cladding Layer Heat-seal Parameters Optimization of Aircraft Sound Insulation Cotton

目的研究飞机隔音棉制造过程中包覆层的最佳热封参数。方法分析不同的热封工艺参数(热封温度、热封压力、热封时间)对隔音棉包覆层热封强度的影响,建立主要热封参数与热封强度的数学模型。在此基础上,利用LabVIEW对材料进行热封强度仿真计算和热封参数优化设计,并对数学模型得出的最佳热封工艺参数进行实验验证。结果模型的理论计算值与实验结果基本一致,验证了模型的正确性。结论实现了隔音棉材料热封参数的优化,为某飞机制造公司在隔音棉热封中热封参数的设定提供了参考。

Objective To study the optimal heat-seal parameters of the cladding layer in the manufacturing process of the aircraft sound insulation cotton. Methods The effects of different heat-seal processing parameters （heat-seal temperature, time and pressure） on the cladding layer heat-seal intensity of sound insulation cotton were analyzed, and mathematical models were established for main heat-seal parameters and heat-seal intensity. Based on this, heat-seal intensity was simulated and heat-seal parameters were optimized by LabVIEW software, in order to verify the mathematical models. Results The model calculated data was essentially identical to the experimental data, and the accuracy of the model was verified. Conclusion The optimization of heat-seal parameters was realized, which provides reference for setting the seal-heat parameters in the sound insulation cotton heat-seal processing of an aircraft manufacturing company.
