The transverse free vibration model of the rubber conveyor belt with the steel rope core is established based the small deflection theory of the orthogonal anisotropy sheet model. By using the classical solution method. the analytical solutions of the SFSF boundary model of the lower branch conveyor belt. the SCSC boundary model of the upper branch slot shape bottom. https://cosmeticssquadets.shop/product-category/lip-balm/
