摘要：Road transportation has thrived amidst urbanization, leveraging its advantages, yet concurrently generating detrimental environmental vibrations. This vibration issue becomes particularly crucial in production workshops housing precision instruments, although limited research has been undertaken on this matter. This study conducted a field test to investigate the impact of road traffic-induced vibrations on the micro-vibrations within a workshop equipped with precision instruments. Ground-borne vibrations induced by road vehicles on the transmission route diminish with increasing propagation distance, exhibiting peak responses around 10 Hz. The workshop experiences vibrations originating from both machinery operation and vehicular traffic. Specifically, vibrations from machinery operation are concentrated in the frequency range above 20 Hz, whereas those resulting from vehicular traffic focus on the frequency range below 20 Hz. The passage of heavy trucks induces notable vibration responses both on the ground and within the workshop, with vertical vibrations being particularly pronounced. Within the workshop, the second floor exhibits greater vibrations than the first floor above 20 Hz, attributed to the stimulation of instruments installed there. The micro-vibration of the first and second floors in the workshop far exceeds the VC-C limit . Consequently, it is imperative to consider the effects of road traffic and production machinery on micro-vibrations in the workshop. The gathered data can serve to validate potential numerical models for predicting vibrations caused by road traffic, guiding vibration assessment efforts during the planning and design stages of roads. ? 2023, The Authors.
