This study examines the impact of resonant elements on the vibration absorption capability of car door constructions. Utilizing vibration theory, ascertain the open and closed intervals of the absorption spectrum (bandgap) to enhance vibration attenuation efficacy. Simulation results indicate that resonant elements can provide a broad bandgap, are readily produced using 3D printing technology with steel materials, and can be simply integrated into door frames. The use of resonant elements into doors markedly improves vibration absorption capabilities while maintaining the structural integrity due to their small dimensions. The augmentation in volume resulting from the incorporation of these items is minimal, therefore the impact of weight can be disregarded in the comprehensive study. This outcome illustrates the method's superiority over conventional approaches that frequently necessitate material alterations or an augmentation of the total system volume. The study validates that the implementation of resonant elements constitutes an efficient, lightweight, and viable method for mitigating vibrations in door structures, with potential for extensive application in engineering systems necessitating vibration control without modification of the original structure.
