A Distributed Parameter Dynamic Model of the Human Forearm.
NIOSH 1977 Apr:142-145
The human hand-arm system had been modeled previously as a lumped parameter system. To provide better anatomical representation, a distributed parameter model has been developed. This model is composed of dual homogeneous Euler-Bernoulli beam elements representing the bones of the forearm; a simple discrete parameter system is used to represent the properties of the hand local to a vibrating handle. Validity of the model was verified by experiment; above 700 hertz there was considerable divergence of the model and experimental results, probably due to inadequacies of the model of the hand.
