摘      要：In this paper we develop an elasto-dynamic model of the human arm that includes effects of neuro-muscular control upon elastic deformation in the *** elasto-dynamic model of the arm is based on hybrid parameter multiple body system variational projection principles presented in the companion *** the technique is suitable for detailed bone and joint modeling,we present simulations for simplified geometry of the bones,discretized as Rayleigh beams with elongation,while allowing for large *** of the upper extremity is simulated by incorporating muscle forces derived from a Hill-type model of musculotendon *** effects of muscle force are modeled in two *** one approach,an effective joint torque is calculated by multiplying the muscle force by a joint moment ann.A second approach models the muscle as acting along a straight line between the origin and insertion sites of the *** arm motion is simulated by utilizing neural feedback and feedforward *** illustrate the combined effects of neural control strategies, models of muscle force inclusion,and elastic assumptions on joint trajectories and stress and strain development in the bone and tendon.
