Abstract


The main functions of a vehicle cabin are to provide a comfortable and relaxing environment for its
operator and to protect them from vibrations, noise, and other adverse influences. Modern
agricultural tractor cabins are complicated, high-efficiency systems, and the goal of their
development is to reduce their negative influence on the environment. Main factors for thermal
comfort are the dry-bulb temperature, relative humidity, surrounding surface temperature, and air
motion. A tractor cabin was created with help of CREO software. Material selected for the cabin is
steel. Software used for meshing and analysis of tractor cabin is STAR CCM+. Parameters
considered for this analysis are 1) Air flowrate, 2) Windshield coating configurations. We created
thermocouple points on different body parts of manikin. Coating used on windshield is tinting.
Location of Ac vents are on above the windshield, On the dashboard and under the dashboard. Main
goals are achieving higher fueleconomy and lower emissions. After the completion of general setting,
pre-processing, and post-processing procedure. We got the average temperature value 26.4°C for
validation and we tried different airflow rates, their average temperatures are following in summer:
22.63°C and in winter: 22.65°C.
