“…This work concentrates on diagnosing and studying the mechanical vibrations produced in a cargo vehicle while adhering to ISO 2631 [ 1 ]. An additional step is to consider security measures for data protection and end-user safety, such as the drivers of freight vehicles [ 13 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. These works concern the investigation, analysis, and forecasting of the impact of vibration on cargo vehicle drivers.…”

This study presents the design and implementation of an electronic system aimed at capturing vibrations produced during truck operation. The system employs a graphical interface to display vibration levels, ensuring the necessary comfort and offering indicators as a solution to mitigate the damage caused by these vibrations. Additionally, the system alerts the driver when a mechanical vibration that could potentially impact their health is detected. The field of health is rigorously regulated by various international standards and guidelines. The case of mechanical vibrations, particularly those transmitted to the entire body of a seated individual, is no exception. Internationally, ISO 2631-1:1997/Amd 1:2010 oversees this study. The system was designed and implemented using a blend of hardware and software. The hardware components comprise a vibration sensor, a data acquisition card, and a graphical user interface (GUI). The software components consist of a data acquisition and processing library, along with a GUI development framework. The system underwent testing in a controlled environment and demonstrated stability and robustness. The GUI proved to be intuitive and could be integrated into modern vehicles with built-in displays. The findings of this study suggest that the proposed system is a viable and effective method for capturing vibrations in trucks and informing drivers about vibration levels. This system has the potential to enhance the comfort and safety of truck drivers.

“…A high percentage of workers in the European Union are exposed to whole-body vibration (WBV), according to the European Agency for Safety and Health at Work (EU-OSHA) [1]. WBV exposure is an inseparable part of the operations performed by vehicle drivers and equipment operators [2][3][4][5][6]. This exposure is epidemiologically related to the most common work-related health problems in the EU, namely musculoskeletal disorders (MSDs) [7].…”

Musculoskeletal disorders, which are epidemiologically related to exposure to whole-body vibration (WBV), are frequently self-reported by workers in the construction sector. Several activities during building construction and demolition expose workers to this physical agent. Directive 2002/44/CE defined a method of assessing WBV exposure that was limited to an eight-hour working day, and did not consider the cumulative and long-term effects on the health of drivers. This study aims to propose a methodology for generating individualised models for vehicle drivers exposed to WBV that are easy to implement by companies, to ensure that the health of workers is not compromised in the short or long term. A measurement campaign was conducted with a professional driver, and the collected data were used to formulate six artificial neural networks to predict the daily compressive dose on the lumbar spine and to assess the short- and long-term WBV exposure. Accurate results were obtained from the developed artificial neural network models, with R2 values above 0.90 for training, cross-validation, and testing. The approach proposed in this study offers a new tool that can be applied in the assessment of short- and long-term WBV to ensure that workers’ health is not compromised during their working life and subsequent retirement.

The influences of the seat suspension on the comfort level, and stability of the bus driver are analyzed using a three-degree-of-freedom (3DOF) quarter-vehicle model. The influences are analyzed through the effects of seat suspension damping ratio ξ se on driver frequency weighted acceleration a w (m/s2) (comfort level) according to ISO 2631:1-1997 standard, the ratio of driver acceleration and gravitational acceleration a/ g (vertical stability). With random excitation according to ISO 8608, considering the same vehicle speed value v (km/h) (in the region of 10 – 20 (km/h)), the decrease of ξ se increases the a w value, this result leads to the reduction of comfort level; Considering the same ξ se value, a w value decreases as increasing v value. With transient excitation according to IRC 99 – 1988, considering the same v value, the smaller ξ se creates the larger a/ g value; Considering the same ξ se, the value of a/ g increases and reaches the extreme in the vehicle speed range 20 – 30 (km/h), outside this speed range the value of a/ g decrease.
