The Research Of Human Body Dynamics Modeling And Simulation Based On ADAMS

Human body dynamics takes aim at the modeling methods of human body and the analysis of the kinematics and dynamics characteristics of the result model. Human body dynamics is one of the foundation subjects of the research of apery mechanism and has been widely used in the areas such as aero and automobile. The research of human body dynamics is of real significance in the design of mechatronic products and exercise healing mechanism.At first the structure/function/movement of human skeleton, articulation and muscles are presented, then the human body model is simplified based on multi-body dynamics, and the human dynamics model is built up in ADAMS. At last the walking process is simulated and the dynamics parameters are recorded and compared with factual data.The research results of this paper are:1. The thinking of specified-movement-oriented human body modeling is broken through. The model built in this paper is fit for most free movement.2. It is brought forward that regarding forearm as a rigid body is reasonless. The thinking of dividing forearm into two rigid-bodies is affirmed.3. Walking pace and balance control are involved in the walking process. Walking pace and support phase are analyzed and articulation movement parameters are designed by STEP mathematics functions, and fuzzy rule container is constructed to adjust articulation angle for body balance.4.The dynamics simulation of walking process is completed successfully. The factual data of human walking is used for verifying the simulation data. At last the modeling thinking is proved to be accordant with anatomy and multi-body dynamics.
