The numerical analyze of the human behavior in a vibrational medium

摘要: The vibration environment is a common man-made artificial surrounding with which humans have limited tolerance to cope due their body dynamics. This paper studies the dynamic characteristics of standing human system in environment. main result multi degrees freedom lumped parameter model that synthesizes two basic First consists global dynamics, apparent mass phenomenon, including systematic set parameters for simulating various conditions like posture, backrest, footrest, muscle tension, and directions second local represented by pelvis/vibrating seat contact, using cushioning interface. provided an analytical tool dynamics research. It also enabled primary design. Combining geometry mechanical structure under large deformation into enables successful analysis human/seat interface provides practical results protection focuses on our contributions numerical experimental models this area.
