Abstract To study the walking gait period of an assistant leg, the method using virtual dynamics software to simulate walking process was proposed. With combination of human body structure and gait planning, research on the work principle and the function implementation of an assistant leg was carried out. Design of the mechanical structure of an assistant leg was made and its 3D model combining with its corresponding human body model was established and ADAMS was used to simulate its walking gait. The result proves that the assistant leg meets the requirements of human walking, and it is technically feasible. The proposed method provides reference for physical prototype machine and is of great significance for research on control algorithm for an assistant leg.
