Abstract

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.

考虑被俘路面的振动激振器能量激励效应及结构优化研究

本文重点研究了振动捕获的道路重量对振动振动器能量激励的影响，以及在有道路而不是底板与地面直接接触时振动振动器底板的优化。为此，基于基础表面的振动衰减公式，得出了捕获道路重量的变化规律。建立并验证了考虑捕获道路重量的激励动力学模型。分析了振动系统的能量激励效应。采用拓扑优化方法对底板进行了优化，并对优化前后振动振动器的激励效果进行了对比研究。在振动器的能量传递过程中，反应物质会消耗大部分能量，实际输出的振动波能量仅为总能量的5.5%。八边形工字钢底板可减轻其重量442 kg，在保证刚度的同时，能量激励效果相对提高了18.2%。该研究将为考虑被捕获道路的重量提高振动振动器的能量激励效果提供参考。
