Abstract

The invention belongs to the field of biomechanics, and particularly relates to an experimental device for performing multi-type, angle and force collision on human skull and maxillofacial bone. The experimental device comprises a pendulum impact device, a replaceable rammer, an impact force and acceleration measuring system and a multi-angle height adjusting model mounting platform. The inventionaims to realize an impact test of human skull and maxillofacial bone under different conditions. According to the experimental device, a scale spherical hinge and a height adjusting chute are additionally arranged on the model mounting platform, so that multidirectional accurate adjustment of a model is realized; the detachable rammer is adopted, so that the collision conditions of different sizes, shapes and materials are realized; and an impact force sensor and an acceleration sensor are additionally arranged, so that the acceleration and the impact force are obtained in an experiment. Theexperimental device provides more accurate and comprehensive experimental conditions for researching the damage form, tolerance limit, function damage degree and protective measures of the human skulland maxillofacial bone. Meanwhile, an experimental system can be applied to more fields not limited to biomechanics.

Description

technical field [0001] The invention belongs to the field of biomechanics, and in particular relates to an experimental device for simulating various angles and force impact tests of various types of impact objects on human skull and maxillofacial bones. Background technique [0002] In various sports or traffic collision accidents, head and maxillofacial injuries are the most common types of serious injuries, and head injuries are one of the main causes of serious injuries or deaths, while maxillofacial injuries are not as life, but often lead to disfigurement, loss of function and sequelae, causing serious physical and psychological trauma. Therefore, it is of great practical significance to carry out research on the injury forms, injury degrees, tolerance limits and protective measures of the human skull and maxillofacial bones. [0003] At present, the mechanical analysis of maxillofacial impact injury is mainly carried out by combining numerical simulation or simulatio...
