This paper describes the impact absorption characteristics of a human arm when catching an object. The impact force acting on the human arm is measured, and the time trajectory of the force is analyzed. Experimental results show that the palm of the hand absorbs the impact by reducing the peak value of the force time trajectory and the wrist and the elbow do it by reducing the force acting time. These characteristics are explained by the simulation of a catching motion model constructed of a spring-mass-damper system with the Hertz force model, by which the impact phenomenon can be simulated. It is shown that the mass effect decreases in the absorption by the palm of the hand compared with impact to a rigid object, and the damping effect decreases in the absorption by the wrist and the elbow compared with only the palm.
