Abstract

|
|
|
MADYMO(R) (Mathematical Dynamic Models) is a computer software with a multibody dynamics solver, which can be employed to reconstruct and interpret dynamic motions of the human body in impacts. The human model of the software is composed of many ellipsoidal structures, which makes it possible to interpret dynamic whole-body motions and calculate applied forces to human body parts. However, this model has some disadvantage to interpret injuries of the smaller body parts such as ribs, vertebral bodies or intervertebral discs. After achieving the finite element bone model produced by CT and software BIONIX BODYBUILDER(R) (finite element modeller), we tried to import this model into the MADYMO(R) and parts of the human bone model were successfully imported to it. Importing of the whole bone model was, however, impossible because of the numerous elements. The coming experiments need to reduce the number of elements in the whole human bone model and incorporate ligaments, tendons and muscles into each separated part of bone models.
