The project is to create a simple MATLAB program to calculate the Mass Moment of Inertia (I) of a Body Segment. The Mass Moment of Inertia is given by the following equation:
= 2
Where the mass of segment is given by the table below for a segment and ks are given in the other table below. The ks tables have k1, k2, and k3 per segment. K1 is used for the Anterior-Posterior Axis (typically used for abduction/adduction movement of the segment), k2 is given for the transverse axis (typically used for flexion/extension), and k3 in the axis longitudinal to the segment (typically used for internal/external rotation). So, you need to create a MATLAB program that for a given segment and direction (antero-posterior axis, transverse axis, or axis longitudinal to the segment), it should calculate the Mass Moment of Inertia.
Mass of segments as a percentage of the bodyweight:
Link | Male | Female | ||||
5% | 50% | 95% | 5% | 50% | 95% | |
Hand | 0.4 | 0.4 | 0.6 | 0.3 | 0.4 | 0.5 |
Forearm | 0.9 | 1.2 | 1.6 | 0.7 | 1.0 | 1.4 |
Ks Values: The mean values of mass and inertia characteristics of the human body segments (n =100)
Segment | K1 (%) | K2 (%) | K3 (%) |
Foot | 25.7 (0.95) | 24.500 (0.80) | 12.4 (1.21) |
Shank | 28.1 (0.63) | 27.5 (0.61) | 11.4 (1.96) |
