Abstract

A bio-mechanical impact test table comprises a control system, a transverse impact system and a longitudinal impact system. The transverse impact system comprises a transverse motor, a transverse ball screw, a transverse compression spring, a front slide table, a rear slide table, a transverse impact head, a transverse guide rail and a lifting worktable; the longitudinal impact system comprises a longitudinal motor, a longitudinal ball screw, a longitudinal electromagnetic hasp, a longitudinal compression spring, an upper slide table, a lower slide table and a longitudinal impact head. During test, an impacted object is fixed on the worktable according to different impact parts, and the front slide table or the lower slide table can impact horizontally or vertically under the action of elasticity of the springs after controllable connection is disconnected. The bio-mechanical impact test table can complete impact test of different body parts, motion parameters can be captured being combined with a kinematic measuring device during impact, and original kinematic and dynamic data can be comprehensively, completely and effectively acquired during impact.

Description

technical field [0001] The invention relates to a device in the technical field of electromechanical systems, in particular to a biomechanical impact test bench. Background technique [0002] Research on the damage mechanism of fractures caused by high-energy impacts such as car accidents and falls from heights is currently the focus and hotspot of research in the field of human biomedicine. Patients often die due to delays in treatment or failure to obtain timely assistance due to internal bleeding. According to statistics, the mortality rate due to impacts such as car accidents is as high as 40%, occupying a large amount of medical resources and causing huge losses to individuals and society. The impact direction and other parameters can quickly judge the patient's injury, and take effective treatment measures in time has become an important topic to save lives. Due to the complexity of the human body structure and the different types of trauma caused by the impact direct...
