【 摘 要 】
Excessive natural frequency (ωn) in a system is very undesirable because it will damage the system. This study used Single Dynamic Vibration Absorber (SDVA) to reduce translational and rotational vibrations to changes in the position of excitation sources. Prototype was built with a 2-DOF translation-rotation vibration system and with the addition of SDVA to 3 DOF. The prototype was modeled mathematically and simulated to determine the vibration response to changes in vibration characteristics that occured. Simulation was done by varying the change in SDVA excitation distance to the main system mass center, and change in moment arm distance. The result of the translation and rotation direction attenuation was able to reduce vibration. The main system was not coupled if dva is in the center of the massso it does not affect rotational motion. The largest percentage reduction occurs in the natural frequency area of the system 12.9 Hz on DVA the ratio of negative moment arm rl = -0.5 for the translation direction of 94.81%, and the rotation direction of 79.48% with an excitation distance of 0.148 m.【 预 览 】
