METHODS AND SYSTEMS FOR NUMERICALLY SIMULATING MUSCLE MOVEMENTS ALONG BONES AND AROUND JOINTS

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for numerically simulating muscle movements along bones and around joints.SOLUTION: A computerized model containing a plurality of truss elements along with one or more rollers is used. The truss elements are configured for modeling muscle fibers while each roller is configured for a joint. Each truss element includes two end nodes and is configured with or in association with a muscle bio-mechanical property model. Each roller is fixed at the location of a corresponding joint. To simulate muscle fiber movements around the joint, each pair of truss elements straddling a roller is adjusted dynamically in a time-marching simulation (e.g., computer simulation of an impact event of an automobile and one or more occupants). The adjustments are performed at each solution cycle of the time-marching simulation. The adjustments include two types, namely, "slipping" and "swapping".
