The characteristics of human muscles are determined human muscles are determined by the sensitivity analysis method. [1-4] In this study, the behavior analysis of human right behavior analysis of human right arm under impact condition was performed by was performed by creating the human model of Korean young men and Table 1. Physical condition of Physical condition of Korean young men both the impact force and the applied load of the both the impact force and the applied load of the specific joint through a simulation of occurred joint through a simulation of occurred Stature Stature Weight Forearm Model condition with hammering impact was obtained was obtained. The (cm) (kg) (cm) right arm was modeled by muscle-skeleton elements skeleton elements Analytical 174 70 32 to obtain the behavior of right arm of human under avior of right arm of human under impact condition, where physical and geometrical physical and geometrical Experimental 174 70 32 properties of human body such as Young's modulus, properties of human body such as Young's modulus, Size Korea [5] 174 69 33 shear modulus, cross sectional area, length, density, shear modulus, cross sectional area, length, density, moment of inertia and position were defined. Based moment of inertia and position were defined. Based In this study, physical condition of condition of basic model of on the numerical model of the right arm, the impact odel of the right arm, the impact 50 percentile Korean young m young men is referred to the response of the right arm was obtained. By the response of the right arm was obtained. By the report of Size Korea 2005 [5] as Table 1. In case of comparison with the experimental results, the model comparison with the experimental results, the model human modeling for operating the maintenance tool human modeling for operat of the right arm was verified. and shooting the small arms, and shooting the small arms, perpendicular posture of forearm and upper arm is modeled basically [6]. of forearm and upper arm is The behavior of human right arm under impact human right arm under impact Forearm is horizontal and upper arm is vertical Forearm is horizontal and upper arm is vertical as condition is affected by the characteristic of the condition is affected by the characteristic of the Fig. 1. human muscle-skeleton model. The behavior of he behavior of human right arm affects the further research activity the further research activity in biomechanics and survivability study. study. The impact by hammering is transferred to the segment of the to the segment of the human right arm. The finite element model and the human right arm. The finite element model and the analysis method were needed to analyze and to analyze and compare with experimental results. 2 Characteristics of Analytical Model Model 2.1 Biomechanical Model of Human Right Arm Biomechanical Model of Human Right Arm The biomechanical model is based on the is based on the finite element method to the different aspects of to the different aspects of biomechanical human body movement, which is human body movement, which is kinematical and dynamical analysis of spatial kinematical and dynamical analysis of spatial Fig. 1.
