Mathematical Modelling and Computer Simu

0.0

The text presents a scientific approach to the problem of biomechanical systems description. This approach is based on development of a universal anthropomorphic model and employment of methodology of limitational dynamic modelling (IDM). The novelty of this approach is that there appears a possibility to operate with a whole class of models, derived from the universal model on the basis of motion separation principle. This is followed by utilization of iterational procedures realizing the method of successive approximations and resulting in description of the real motion with the pre-set accuracy level. Use of the IDM has ascertained certain laws governing human locomotions: presence of so called controlling and stabilizing interlink moments, wavelike speeding of forces extremums along the kinematic chain, adaptation of control functions for astronauts motion coordination preservation. The principal reason for the deterioration of functional state of skeletal-muscular apparatus of astronauts was also determined. The book has 5 chapters which contain a review of problems arising in motion modelling; a description of the universal anthropomorphic model; fundamentals of IDM; examples of motion analysis; and synthesis and optimization.
