This study was carried out to evaluate the shock-proof of a large scale motor for the naval vessel using full transient dynamic analysis. Finite element models for main assemblies (motor frame, rotor and stator assembly) were consisted of the tetrahedral solid elements and the equipments which installed in the upper side of the motor were substituted the mass elements. And we also modelled resilient mounts of a motor using the beam elements with appropriate directional stiffness. The analysis was conducted applying directional triple half triangle shock wave to the motor using ANSYS 11. As a result, we could find the motor to satisfy the design criteria of the maximum stress and deformation.

This paper examine developments of intelligent prosthesis system by analysising founction of New C-Leg is made by Otto Bock in Germany. At first, it will describe gait pattern of normal people, and that will describe methode of appling in New C-Leg. Second, it will introduce C-soft that is finely changing movement with matching users habit. At least, it will describe mode change about exercise.
