In recent trends, membrane structure has increased its applications in space missions due to its significant advantages, such as light in weight, higher folding and packaging efficiency, ease of deployment, and low on-Board volume requirement. The wrinkling and low natural frequency of vibration are the major problems with the membrane structure. This research presents a novel methodology of Kapton-Kevlar material combination for a planar membrane reflector to enhance anti-vibration and anti-wrinkling capabilities of the membrane structure. The comparative study is made for the wrinkle area, RMS error, and natural frequency of vibration with the employed approach. This study provides new insights into a material combination technique to increase performance characteristics of the space-borne membrane reflectors. The outcome of the wrinkling analysis is compared and found to be consistent with the method available in the literature. From the simulation results, it is observed that wrinkles are reduced, and the natural frequency of vibration is also increased significantly with the proposed method.

增强平面膜反射器抗皱,抗振特性的材料组合技术研究

在最近的趋势中,膜结构由于其显着的优点而增加了其在太空任务中的应用,例如重量轻,折叠和包装效率更高,易于部署以及对机载体积的要求较低。起皱和振动的固有频率低是膜结构的主要问题。这项研究提出了一种用于平面膜反射器的Kapton-Kevlar材料组合的新方法,以增强膜结构的抗振动和抗皱能力。使用所采用的方法对皱纹区域,RMS误差和固有振动频率进行了比较研究。这项研究为增加空间传播的膜反射器的性能特征的材料组合技术提供了新的见识。比较起皱分析的结果,发现与文献中可用的方法一致。从仿真结果可以看出,所提出的方法减少了皱纹,并且振动的固有频率也显着增加。
