Human Body Inertia Properties

WithRonald L. Huston

Consider a representation or model of the human body as in Figure 9.8, and as shown again in Figure 10.1. As noted earlier, this is a finite-segment (or lumped-mass) model with the segments representing the major limbs of the human frame. Consider a typical segment or body, B k of the model as in Figure 10.2. In our analysis in Chapter 9 we discovered that the inertia forces on B k are equivalent to a single force F k * passing through the mass center G k of B k together with a couple with torque T k * where (Equations 9.24 and 9.27) () F k ∗   =   − M k   R a G k
