X-Suspended Handles for Heavy-Duty Hand-Held Vibration Machines
摘要
Prolonged exposure to intense vibration from heavy-duty tools such as jackhammers poses serious health risks to construction workers, making effective vibration protection essential. This study introduces a novel passive anti‑vibration exoskeleton designed for jackhammers and road breakers that is portable, cost‑efficient, and highly effective in reducing vibration during drilling and impact operations. Inspired by animal limb structures, the exoskeleton employs a bio‑inspired X‑shaped configuration to exploit beneficial nonlinear dynamic properties, significantly attenuating vibration transmission without sacrificing load‑bearing capability. Theoretical analysis, simulations, and experimental validations demonstrate that the proposed technology markedly improves vibration suppression while maintaining operational efficiency, offering a promising solution to a long‑standing challenge in construction engineering.
