Human intra-abdominal pressure testing method based on musculoskeletal biodynamics

The invention relates to a human intra-abdominal pressure testing method based on musculoskeletal biodynamics. The human intra-abdominal pressure testing method comprises the steps of acquiring a human whole body musculoskeletal model customized according to a human body; establishing musculus trasversus abdominis to surround a contact rigid body, representing a musculus trasversus abdominis group and a diaphragm muscle group through a muscle-tendon model, and further creating a muscle group model of musculus trasversus abdominis and diaphragm muscle of the human body; enabling intra-abdominal pressure to be equivalent to equivalent intra-abdominal pressure in the horizontal direction and the vertical direction so as to create a human intra-abdominal pressure equivalent force model; and capturing each posture joint angle of a certain standing posture of a tester, and inputting each posture joint angle into a human musculoskeletal biodynamics model formed by combination of the established models; and calculating the intra-abdominal pressure value under the posture. The method can be used for solving the problems that under different postures or actions, the intra-abdominal pressure is unknown, and is difficult to directly measure, the measuring cost is high, and the like.
