Dynamic Response Characteristics Analysis of Biomimetic Foot during Ground Contact Instant

Abstract In this paper, the dynamic substructure method is applied to analyze the touch instant response characteristics of commonly used materials for foot mechanism, and the touch instant of quadrupedal mechanism is taken as an example for corresponding analysis. This paper firstly takes a walking mechanism as the research object, simplifies the contact model, and introduces the dynamic substructure solving method to construct the corresponding numerical model; then the dynamic substructure method is used to solve the transient corresponding characteristics of the leg components under different materials and different loading conditions, and obtain the corresponding transient corresponding characteristics of the collision force, etc. At the same time, the material characteristics are synthesized to analyze the transient response characteristics of different materials for the bionic mechanism, so as to provide a comprehensive analysis for the transient response characteristics of different materials for the bionic mechanism. At the same time, in order to analyze the transient response characteristics of different materials, the material characteristics are synthesized, so as to provide a basis for the study of transient mechanical properties of different materials of the bionic mechanism. Finally, the transient characteristics of foot-ground contact are experimentally verified by a high-speed camera system. Finally, this paper provides some theoretical support and methodological reference for the mitigation of transient response of foot-ground contact.
