Mining Contract: Development of Biomechanical Model of Knee to Reduce Injuries in Mining
This contract will develop and validate a finite element model of a knee. Experimental inputs will be used to drive the model such that the forces and stresses of the internal structures (e.g., cartilage, ligaments, meniscus) may be evaluated for postures associated with low-seam mining.
Contract Status & Impact
The contract is complete. To receive a copy of the final report, send a request to OMSHR@cdc.gov.
Large motion of the meniscal tissue and complex contact stresses resulted in the contractor being unable to run and validate the finite element model. The contractor refocused the model on the ligaments which could be modeled as simple spring elements. Using experimental techniques and robotic technology, the contractor was able to validate the predicted ligament forces in the spring model. This model may be used to evaluate the forces in the ligaments—but not the cartilage and meniscus as originally intended—while in postures associated with low-seam mining.
