Abstract

Abstract

The process of head impacting with elastic plane was modeled as a response of vibrant system, and the method of mechanical network figure and mechanical impedance was used to resolve this problem.Based on its structure, head was viewed as a vibrant model, which concludes the masses of scalp and bone in the impact area, the masses in the other part of the head and the brain, the stiffness of the head, and the damper of the scalp and brain.Also the elastic plane was simplified as a vibrant model including mass, stiffness and damper.The models were transformed into mechanical girding figure at violent vibration poin.When the initial impact speed is known, the impact force of the system,the impact acceleration of the head, the elastic deformation of the plane and the fixed frequency of the system can be worked out by calculating the velocity impedance at the violent vibration point, the results fit the test data well, which proves that this method is available for the analysis of the dynamic response of the system under impact.
