Parkinson’s disease is a central nervous system disorder, whose effects and symptoms are evident in the physical movement and appearance of the patient. The frequency range of 2–10 Hz is mostly where the balanced muscles movement of the patients happens. This paper seeks to create a wearable device that is capable of suppressing these tremors within a specific frequency range by examining the system with and without dynamic vibration absorber (DVA) is done for three main positions, normal, short, and long positions; so that the stiffness and the natural frequency changes. The dynamic vibration absorber, tremor suppression will be achieved. The dynamic vibration absorber is set to be a spring-mass system. From the findings of the experimental studies realizing such a device is possible and that varying the absorber parameters of the device can achieve different levels and degrees of tremor suppression. The proposed DVA showed more than 60% of the vibration suppression. The proposed method is reliable for vibrations suppression for tremors of Parkinson’s disease and it is simple without using multiple devices so that it is more comfortable for patients. |
