【 摘 要 】

The transient dynamic response exists between the lower limb and the ground at the moment of a quadruped's paw-strike movement. In order to analyze the property of the transient dynamics, which is a highly nonlinear problem, firstly, the tibia bone of the hind limb was selected as the study material in this paper, and the elastic modulus was precisely determined by the nano-indentation experiment; then the contact-impact process between the tibia and the ground was simplified for the numerically solution; finally, the velocity wave, acceleration wave, displacement wave propagating along the length of the simplified model was obtained.
