Medición y análisis de vibraciones mecánicas en un bus de transporte de pasajeros y sus efectos en la salud y el confort mediante la norma ISO 2631

Abstract

The present project you have as finality of measuring and analyzing mechanical vibration, in a bus of transport of passengers to evaluate the possible effects in the health and comfort. The vehicle, generate vibrations for sources of excitation external (irregulaties surface) and internal (Engine, transmission system, other). The vibrations can generate diversity of harmful effects on the human body; goes from sensations of discomfort or disturbance until effects on soft tissue and into the circulatory system. The control of motion vibrations, using computational program Ansys and Matlab, it is studied the beginning of operation through finite element method. To measure the mechanical vibration is used equipment and instruments on board the transport unit, it is installed accelerometers in the driver's seat and vehicle parts, the data are processed, analyzed and compared, using the method of evaluation located in the norm NTE INEN ISO 2631-1 and Royal Decree RD 1311/2005. This has limits daily exposure to mechanical vibration in jobs over a period of 8 hours A (8).
