Model Creation and Parameter Identification of Gun-Shoulder System
Abstract:
This paper analyzed mechanical admittance for contacting point between gun and shoulder; identified inherent characteristic parameters, established model of gun-shoulder system base on plentiful experiments. The results that can not only reflect mechanical impedance property of the shoulder, but also embody the equivalent dynamic response property of man-gun system. Then, making statistics analyses for different shooter, confirming receiving-shoulder’s model parameter of man-gun, providing academic base for building mechanics model of man-gun.
