The study consisted of estimating the amount of energy dissipated by varying the number of spring leaves and preloads, through the use of clamps, both numerically and experimentally. Through compression tests, the behavior of the spring was observed through a force-displacement relationship. The strain energy and total frictional dissipation were obtained by integrating the hysteresis curve. Numerical modeling was performed with the commercial finite element package Abaqus in a quasi-static state. The results obtained show that the preloads influence the energy dissipation of the spring, increasing mainly when these are implemented with a greater number of leaves, up to 189%. With these results, it is possible to propose a configuration that allows the greatest amount of energy to be dissipated passively and, consequently, to improve the damping of the vehicle in reference to the commercial spring. En este trabajo se presenta la evaluación de la influencia de las precargas de ensamble y de la cantidad de hojas en el fenómeno de disipación de energía de un muelle a través de un estudio paramétrico. El estudio consistió en estimar la cantidad de energía disipada al variar el número de hojas del muelle y la precarga, a través del uso de abrazaderas, tanto de forma numérica como experimental. Mediante ensayos de compresión se observó el comportamiento del muelle mediante una relación fuerza-desplazamiento. Se obtuvo la energía de deformación y la disipación por fricción total mediante la integración de la curva de histéresis. Se realizó un modelado numérico con el paquete comercial de elementos finitos Abaqus en estado cuasi estático. Los resultados obtenidos demuestran que las precargas influyen en la disipación de energía del muelle, incrementándose mayormente cuando éstas se implementan con un mayor número de hojas, hasta 189%. Con estos resultados es posible proponer una configuración que permite disipar la mayor cantidad de energía de forma pasiva y, en consecuencia, mejorar el amortiguamiento del vehículo en referencia al muelle comercial.
