“…Other simulations in [35] and real applications in [31] confirmed these results. Evaluating the effects of vibrations on the exposure time by simulation, Sekulić et al [32] concluded that passengers at the bus front and rear overhang might be exposed to vibrations for a very short time.…”

“…Occupational health problems for bus drivers can be prevented by repairing bus seats, on which the driver spends most of his time. Improvements or modifications to the design of the driver's seat including the provision of padding, which has been shown to reduce vibration, will reduce driver fatigue (Sekulić et al, 2018;Manohar, Krishnan and Kumar, 2020). The function of the seat in the vehicle plays an important role, contributing to the rider's comfort.…”

Introduction: Environmental factors such as vibration can affect work fatigue. The previous research results showed that there was a relation between vibration and fatigue, with the use of ergonomic seats by bus drivers. Then conducting experimental research on making ergonomic seat padding made from coconut fiber to reduce the level of vibration and driver fatigue was investigated. The purpose of this research was to analyze the differences in seating vibrations and the bus driver fatigue who did not use a padding seat and one who used it. Methods: The research design was experimental. The research subjects were 42 bus drivers. The vibration intensity was measured using a vibrometer and work fatigue was measured using a reaction timer, then the data were analyzed by T-test. Results: Based on research results the vibration of bus drivers who did not use seat padding was greater than those who did (p=0.001). Those who used seat padding had lower mean fatigue than drivers who did not use it (p=0.001). Conclusion: Vibration and work fatigue in bus drivers who did not use a padding seat was greater than those who used it and the difference was statistically significant. The use of ergonomic seating for bus drivers was very useful for reducing vibration.

Buses drivers are group at risk who often suffer from musculoskeletal problems, such as low-back pain, while bus passengers on the last row seats are experiencing accelerations of high-values. In this paper, the contribution of K-seat in decreasing the above is investigated with a detailed simulation study. The K-seat model, a seat with a suspension that functions according to the KDamper concept, which combines a negative stiffness element with passive one, is bench-marked against the conventional passive seat (PS) in terms of comfort when applied to different bus user's seats. More specifically, it is tested in the driver's and two different passenger's seats, one from the rear overhang and one from the middle part. For the benchmark's shake, both are optimized by applying excitations which correspond to real intercity bus floor responses when it drives over a real road profile. Then, a human model is placed to the seats in order to compare their optimum solutions in terms of user's whole-body vibrations, using objective comfort metrics. Based on the results, the K-Seat improves significantly the comfort of the users (~92%) compared to the PS, while it achieves similar decrease in the maximum values of the user's back accelerations (~97%).
