One of the important forms of smart structure available for various applications in engineering fields is Sandwich beams, for the reason that of variable applications, the capability to withstand at variable loading conditions, significant elastic retaining properties when in comparison to conventional structures. The basic of the present study is to investigate natural frequency ranges for a type of sandwich beam that has been manufactured using natural rubber (NR) that is indigenously available in Tripura, India, in combination to skin material of aluminium alloy 1050 grade. The present article deals with the study of free vibrational characteristics of cantilever sandwich panels (SwPs) with various skin thicknesses. A mathematical approach had been carried out using a standard platform for validating the results obtained from the analytical method. Also, experimentation had been conducted on sample of sandwich panels using Hammer test process and the natural frequencies of the same were obtained. It was found that the results obtained from the analytical method using a standard platform have been in good agreement with the other approach.

三明治梁是可用于工程领域各种应用的智能结构的重要形式之一，原因是可变应用，与常规结构相比具有可变载荷条件下的承受能力，显着的弹性保持性能。本研究的基础是研究使用天然橡胶（NR）制造的夹心梁类型的固有频率范围，该材料可在印度Tripura本地购买，并与1050级铝合金表皮材料结合使用。本文涉及具有各种表皮厚度的悬臂夹心板（SwPs）的自由振动特性的研究。已经使用标准平台执行了数学方法，以验证从分析方法获得的结果。另外，已经使用锤测试方法对夹心板的样品进行了实验，并且获得了其固有频率。发现使用标准平台的分析方法获得的结果与其他方法非常吻合。
