Engineers have for the first time created a simulator that mimics the mechanical behavior of the human torso, which could lead to innovations in the design of medical back supports.
It allows researchers to test different corset designs and configurations without having to test them on people, eliminating significant logistical and ethical issues.
The simulator includes a male torso mechanical test bench and computer simulation models. It includes an artificially additive (also called 3D Printed) chest and thoracic chest, created using modified CAD models derived from CT scans of a human vertebral column, as well as a torso having geometries and other properties closely resembling human tissue and behaving similarly.
The platform can also model and test different configurations and deformities of the spine, such as scoliosis, with different back braces without causing discomfort to human testers.
Researchers can use the platform to collect data on the reduction of flexion, extension, lateral flexion and torsion provided by each back reinforcement.
Although trials on back orthoses may be necessary, the design process will continue to optimize comfort and muscle commitment.
Dr. David Cheneler, a member of Lancaster University's engineering team who created the simulator, said, "Backbends are used both as medical products and for commerce in detail, but existing designs often prove to be heavy, too rigid, indiscreet and uncomfortable.
"Our simulator allows the development of new back braces optimized to limit particular movements but allowing other movements.It could also help in the design of braces and brackets with a targeted restriction of movements, which would be beneficial under certain conditions and would help reduce the risk of muscle loss. "
The researchers tested the platform with two new models of corset, a medical corset and a weightlifting belt.
Jon Harvey, a recent graduate in mechanical engineering from Lancaster University and working on the corset project, said, "This is a great example of the tremendous impact of engineering research, not just in the industry but the quality of life of a population.It also shows how research is used to enhance engineering education at Lancaster University.
