Abstract
In the work was to design the vehicle Baja cockpit for the ergonomic requirement, taking care of the comfort of 90% of the possible pilots, as well as meeting the SAE standard. Studies were on the ergonomic analysis by the Rapid Upper Limb Assessment (RULA) method using CATIA® / RULA software. In the analysis consisted about position pilot on cockpit. Anthropometric measures were taken from a range of members of the Baja / UFV team in the good maneuverability position for each of them. This position was obtained through the positioning of the pilots in an ergometric device, with adjustable dimensions, being: height and inclination of the steering wheel, inclination and distance of the seat and height of the driver. The positions were recorded by means of image having the angulations of the body members obtained through the software SOLIDWORKS®. The anthropometric measures of the occupants were transformed into respective percentiles of the sample. The mean percentiles of each occupant were used to represent the sample analyzed and to perform comfort simulations in CATIA® / RULA. The results of the comfort condition evaluation scores served as parameters for defining the measures of the cockpit. The best cockpit measurement achieved in the simulation was evaluated with scores of two (Negligible risk, no action required), three and four (Low risk, change may be needed, both tree and four score), respectively, simulated with a relative percentile of 65%, 95% and 5%. The all score were satisfactory, since only above four score is medium risk and need change.
