Problems solved by technology

[0003] Through the search of the prior art, it is found that the existing pelvic impact test platform is only suitable for the pelvis with bone structure. Although it can complete the impact on the pelvis, it is not suitable for the pelvis containing soft tissue, and cannot be used to study the impact caused by the pelvic impact. Associated injuries
Also, impacting a pelvis lacking soft tissue does not reflect the real impact response

Abstract

The invention provides a pelvis impact test device which comprises a framework, an impact system, a linear guide rail, a pelvis pre-loading system and a control system, wherein the framework is mounted horizontally; the linear guide rail is connected with the framework; the impact system is connected with the framework and the linear guide rail; the pelvis pre-loading system is connected with the framework; and the control system is connected with the impact system. The pelvis impact test device can impact pelvis containing soft tissues so as to reflect impact responses in the real situation, is applicable to researches on associated injuries brought by pelvis impact, and has the advantages of high universality, easiness in controlling of impact rate and quality, and low manufacturing cost.

Description

technical field [0001] The invention relates to a test device, in particular to a pelvic impact test device. Background technique [0002] Pelvic impact injuries mostly occur in traffic accidents, industrial injuries and falls, and often damage tissues such as soft tissues, arteries, nerves, urinary system and digestive system, forming combined injuries. Finite element models of the human body are becoming an effective tool for studying pelvic-related injuries, but these models must be validated both locally and globally in order for the models to be considered accurate. Relying on the pelvic impact test platform, the force and deformation information of each tissue during pelvic impact can be quantified. [0003] Through the search of the prior art, it is found that the existing pelvic impact test platform is only suitable for the pelvis with bone structure. Although it can complete the impact on the pelvis, it is not suitable for the pelvis containing soft tissue, and can...
