This paper focuses on the influence of road weight captured by vibration on vibratory vibrator energy excitation and the optimization of vibratory vibrator baseplate when there is road instead of direct contact between baseplate and the ground. For this purpose, based on the vibration attenuation formula of the foundation surface, the variation law of the captured road weight is obtained. The excitation dynamics model considering the captured road weight is constructed and verified. The energy excitation effect of vibration system is analyzed. By using topology optimization method, the baseplate is optimized, and the comparative study of vibratory vibrator excitation effect before and after optimization is carried out. In the process of energy transmission of the vibrator, the reaction mass will consume most of the energy, the actual output vibratory wave energy is only 5.5% of the total energy. The octagonal I-steel baseplate can reduce its weight by 442 kg while ensuring its rigidity, and the energy excitation effect is relatively improved by 18.2%. The research will provide a reference for improving the energy excitation effect of vibratory vibrator considering the weight of the captured road.

“…In order to study the influence of the nonlinear contacts on the performance of the system, Lebedev [15] and Beresnev and Lebedev et al [16] propose a model with nonlinear contact springs. Noorlandt and Drijkoningen [17] and Huang et al [18] established nonlinear theoretical models that consider the effects of the surface topography at the interfaces between the vibrator and ground. In addition, to account for the dynamics of the coupling ground, some researchers introduced dynamic stiffness and dynamic damping into the theoretical model to simulate the performance of the vibrator at the elastic half-space surface [19].…”
