Actual Climatic Solicitation on a Vehicle Vs Test of Thermal Fatigue Carried out in Laboratory

The main objective of this work is to study the influence of temperature and weather conditions on the thermal behavior of the plastic components of a vehicle considering several environmental conditions. It is intended to correlate and validate the solicitations currently reproduced in laboratory tests of thermal fatigue to real solicitations obtained in actual field. The developed methodology includes the evaluation of weather maps from several regions of Brazil to identify the critical conditions. The experimental planning comprehends the evaluation of the ambient temperature, the solar radiation and the temperature of the plastic parts, mounted inside and outside a vehicle.
