The Influence of Tractor-Seat Height above the Ground on Lateral Vibrations Gómez Gil, Jaime Gómez Gil, Francisco Javier Martín de León, Rebeca tractor vibration whole-body vibration comfort shock dose suspension terrain health low-back pain cab agriculture Ingeniería mecánica Mechanical engineering Farmers experience whole-body vibrations when they drive tractors. Among the various factors that influence the vibrations to which the driver is exposed are terrain roughness, tractor speed, tire type and pressure, rear axle width, and tractor seat height above the ground. In this paper the influence of tractor seat height above the ground on the lateral vibrations to which the tractor driver is exposed is studied by means of a geometrical and an experimental analysis. Both analyses show that: (i) lateral vibrations experienced by a tractor driver increase linearly with tractor-seat height above the ground; (ii) lateral vibrations to which the tractor driver is exposed can equal or exceed vertical vibrations; (iii) in medium-size tractors, a feasible 30 cm reduction in the height of the tractor seat, which represents only 15% of its current height, will reduce the lateral vibrations by around 20%; and (iv) vertical vibrations are scarcely influenced by tractor-seat height above the ground. The results suggest that manufacturers could increase the comfort of tractors by lowering tractor-seat height above the ground, which will reduce lateral vibrations. 2017-03-16T12:01:57Z 2017-03-16T12:01:57Z 2014-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1424-8220 http://hdl.handle.net/10259/4372 10.3390/s141019713 eng Sensors, 2014, V. 14, n. 10, p. 19713-19730 http://dx.doi.org/10.3390/s141019713 Attribution 4.0 International http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess application/pdf MDPI
