Resumen
Neumáticos no neumáticos, o neumáticos sin aire, son neumáticos portadores de carga que no requieren presión de aire; para ese propósito emplean radios flexibles de poliuretano termoplástico. Estos NPTs se caracterizan por sus radios elásticos, durabilidad y resistencia al desgaste, lo que los hace bastante preferibles en aplicaciones militares, de defensa, industriales y de vehículos espaciales. Sin embargo, presentan limitaciones en su capacidad de absorber impactos y proporcionar confort, lo que restringe su aplicación en vehículos civiles. Los neumáticos híbridos ofrecen una solución que combina los méritos de los NPTs y de los neumáticos neumáticos convencionales. Están compuestos por radios flexibles junto con aire presurizado, lo que les otorga propiedades de ambos lados: la durabilidad de los NPTs y la comodidad de un neumático convencional. Este estudio está altamente enfocado y presenta una comparación entre los NPTs y los neumáticos híbridos. El análisis por elementos finitos (FEA) de ambos modelos indica que, con respecto a la resistencia y durabilidad, los neumáticos híbridos funcionan muy bien para vehículos civiles, aunque su resistencia pueda ser ligeramente menor que la de los NPTs.
