Active Human Body Model

Muscle tensing produces larger axial forces, stress redistribution within bones, increase in effective mass and stiffness, altered kinematics, and less excursion and smaller joint rotations. Voluntary and reflexive muscle activation of vehicle driver is modeled by active joint element at each anatomical joint position (e.g., shoulder, knee, spine, and etc.). There are two basic elements at each joint, i.e., passive kinematic joint element and torque actuator. In this study, both experimental and numerical investigations were performed to identify co‐contraction of human articulated joint and reflexive response upon an external perturbation. The elbow joint with simple 1DOF is selected. Upper body and upper arm of test subject are restrained and the elbow joint angle is asked to maintain its initial position, i.e., keeping the forearm levelled before and after the jerk loading. The same modeling scheme of active response at elbow joint is extensively applied to the whole body model. The version of multi body model (compare with deformable body model) consists of 25 rigid body segments and 24 articulated joints. The SISO (Single‐Input Single Output) problem with 1D active elbow joint model becomes MIMO (Multiple‐Input Multiple Output) problem with whole body model. Human driver’s muscle recruitment strategy of active response to brace against external perturbations belong to the quite complicated behavioral kinesiology involved.
