Abstract:
The state of the art in biomechanical modelling is reviewed with specific reference being made to physical and mathematical idealizations of the human body and its segments. Scale models and anthropomorphic dummies which fall within the physical category are discussed briefly. Mathematical models which are much more prevalent and virtually synonymous with computer simulation models are then considered in two major classifications: deformable element and rigid body representations. The former include lumped parameter, discrete parameter, finite element and continuum models and are commonly used to represent the vertebral column. Examples of rigid body models of the total body response and inertial parameter variety are outlined. Finally, topics relating directly to the construction of sport and locomotion models are discussed. These include considerations for developing a static or dynamic model, utilizing Newtonian or Lagrangian equations of motion, and dealing with indeterminate systems.
