Implementação de um modelo de regressão linear da sazonalidade da severidade de uma estrada de terra

Abstract

The present study presents the severity study to evaluate the level of perfillometric irregularity of the soil (roughness, holes, irregularities of the floor, friction, etc.) promoting efforts on vehicle components on a public unpaved road used by a company in experimental testing. These tests consist of tests to assess the durability of the vehicle components, which can be done by comparing the projected service life of each component and the useful life of the experimental tests. Consideration should be given to the seasonality of the track impacting on the process. Track seasonality can be defined as the change in the level of soil severity throughout the year according to seasons and road use. This study comprises the collection of objective signals or data (acceleration) using sensors (accelerometers) in the field (test path), as well as the treatment and analysis of the acquired data. To achieve this objective, a statistical model of multiple linear regression was implemented, which expresses the seasonal variation of the level of severity of the road as a function of variables. The equation obtained must be able to generate an index that varies in a scale from 1 to 10, with 1 being the softest level and 10 being the most critical for the route.
