Abstract
A simulation system is designed and made for research on dynamical behavior of the clothes, especially on swinging motion of the skirt, covering a human body on walk. The system is composed of two separate functional parts which mimics respectively the buttock and the leg motions of a young woman on walking. This paper describes the make and the performance of the former part (the buttock simulator).
The hip of a manikin (a nude) is installed on a motor-driven mechanism with plate cams of special design so as to rotate over certain angular ranges around two perpendicular axes. The period of the combined rotational motion can be varied from 0.3 to 3.0 sec. The behavior of this simulator is compared with that of the buttock of a woman on walk, the result of which suggests those are well alike.
