Real-time vibration monitoring and analysis of agricultural tractor drivers using an IoT-based system

MAY 25, 2023 | JOURNAL OF FIELD ROBOTICS

 

A recent study conducted by the University of Waterloo, Canada, along with institutes from the UAE, USA, and India, focused on the vibration exposure experienced by agricultural tractor drivers, particularly during soil tillage operations. While previous research mainly examined vertical vibration (z-axis), this study investigated the effects of rotary soil tillage on vibration acceleration, frequency, and power spectral densities (PSDs) along the three translational axes: x, y, and z. To ensure safety during the COVID-19 pandemic, the study utilized an Internet of Things (IoT) module for online data transmission, integrating with existing data loggers. Results revealed that vibration energy was more dominant along the z-axis, exceeding the exposure action value defined by Directive 2002/44/EU. PSDs indicated low-frequency vibrations induced by rotary soil tillage, while the seat-to-head transmissibility (STHT) response demonstrated higher transmissibility along the y and z axes compared to the x-axis. The frequency range of 4-7 Hz was associated with potential cognitive impairment in tractor drivers during rotary soil tillage. This study sheds light on the significant vibration exposure in agricultural settings, emphasizing the need for interventions to ensure the well-being and safety of tractor drivers.
