Analysis of the Dynamic Characteristics of Seat Headrest During Impact

摘要

A energy-absorber device with gravity pendulum of car seat headrest is introduced in this paper, and has a analysis at the dynamic characteristics of headrest by use the method of three component-force detection. A force measuring system from the three component-force detection is brought up to research the model error in impact model, and obtained the point, which the model has a minimum error. Finally, the impact model was simulated with MATLAB by computer, as a results show that the simulation curves are similar to the real response curves very much.
