Abstract

The invention provides a method for constructing the arch rod structure based on the main axis of inertia of the living arch of the foot bone. Based on the center of mass of the living arch of the foot bone, the main axis of inertia of the living bone is solved according to a specific rotation sequence; Three-dimensional rectangular coordinate system; select six maximum and minimum marked points along the three coordinate axes in the established three-dimensional rectangular coordinate system; reverse the six marked points in the reverse order of specific rotation; connect the six points to form a living arch The rod structure of the bone; the rod structure connecting 7 tarsal bones and 5 metatarsals constitutes the arch rod system; a new method for foot statics, dynamics analysis and optimal calculation of the foot wear structure is formed, with the rod structure With a sufficient mechanical model, mechanical analysis can be carried out as needed.

Description

technical field

[0001] The invention relates to the technical field of biomedical engineering, in particular to a method for constructing a foot arch rod system structure based on the main axis of the living bone inertia of the arch of the foot. Background technique

[0002] Many bones in the human body appear in pairs, and the symmetrical tarsal bones and metatarsal bones of the left and right feet form a symmetrical arch. Is there a difference in the symmetry of the arch structure between our left and right feet? If so, how does this difference affect our basic behavior? Does it still follow the principle of "structure and function are unified"? In order to ascertain these problems, it is necessary to establish a mechanical model of the arch structure for mechanical analysis.

[0003] For the law analysis of the force and force transmission of the structure, the finite element method not only has high calculation accuracy, but also can adapt to various complex shapes. T...
