Abstract
A separated prosthetic foot with a transverse arch belongs to the technical field of manufacturing of artificial limbs. The characteristics of the transverse arch of the human foot are combined into the previous transverse-straight carbon fiber foot design to improve the stiffness of the prosthetic foot and reduce the weight of the prosthetic foot. A forefoot part employs a separated curved plate design, and two simple curved plates with different curvatures are used for simulating a complex curved surface of the transverse arch of the human, such that the manufacturing cost is reduced, and the various parts of the sole are non-uniform in stiffness distribution: the outer side of the foot is a single-layer forefoot plate with a smaller curvature and minor stiffness; and the inner side of the foot is a double-layer stacked forefoot plate, and the lower layer plate has a large radius in curvature and stiffness.
