Abstract
The main objective of this paper is to carry out an analysis of whole‐body vibration exposure in drivers and users of bus, taking into account comfort and health for the bus driver and comfort for the passengers, when the bus is subjected to vibrations caused by traveling in irregular road profiles. For this, computational routines are developed in the Matlab software. The Newmark method, which is defined in the time domain, and the spectral analysis method, which is defined in the frequency domain, are adopted. The irregular roads profiles are generated through the procedure proposed by ISO 8608 (1995), and the comfort and health analyses are carried out according to ISO 2631-1 (1997). The results show that the bus driver is exposed to potential damage to his health when he drives in C class roads or above and the passengers of the bus will feel some discomfort even for A class roads, but the situation is worse for a seated person in the rear of the bus.
