Abstract

Backpacks are our commonly used tools to transport materials. However, when people are walking, the center of gravity of the human body will vibrate up and down with a certain amplitude and frequency. The traditional backpack vibrates vertically at the same amplitude and frequency as the human’s COM movement, which will have a huge impact on the human body and increase energy consumption. In this paper, the model of human-backpack is analyzed and an active and passive mixing suspended backpack is designed, which had the ideal effect of reducing acceleration force, amplitude and improving energy efficiency. Through the prototype experiment and the walking test, it is verified that low damping and low stiffness can improve the damping performance of the backpack, and the effect of decreasing amplitude and acceleration force reduction of the backpack under the optimal parameters are obtained.
