Abstract
A rollover test bench has been designed, manufactured, and validated for analyzing the all-terrain vehicle (ATV)-Quad overturn of diverse vehicles in different configurations, such as installing a rollover protection system (ROPS), considering drivers of different physical constitutions, the appropriate use of safety belts, or having a full or empty fuel tank. The main purpose of this research is to determine the tilt angle of the vehicle that triggers the ATV-Quad overturn. The scope of the design and development of the newly conceived bench include the mechanical structure, the electronics and the control. It can simulate static and dynamic rollover in different directions. As a main conclusion, it can be stated that the performance of the test bench was successful, since it allowed for the development of several ATV models, equipped with different dummies, in a variety of configurations. In particular, it was possible to assess the effectivity of the AD-ROPS system (automatically deployed ROPS), regarding the protection of the driver of the vehicle. Moreover, multiple tests, performed with diverse ATV-Quads in the developed bench and in different configurations, have been reported and their results discussed.
Highlights
Agriculture and forestry applications are associated with different tasks, where it is necessary to deploy a significant amount of physical effort to carry them out
In order to achieve this objective, the stages of the design, manufacturing and validation of a test project were carried out. It presented the following main characteristics: The development of the rollover tests reported in this manuscript was carried out using this newly conceived test bench, which was designed and developed for the mentioned research rising of the wheels in the rollover test
The assessment of the choices made in relation with the hydraulic system, which was installed to introduce motion in the test bench, was made from a no-load mechanical test of the bench; that is to say, a test without loading any vehicle onto the bench
Summary
Agriculture and forestry applications are associated with different tasks, where it is necessary to deploy a significant amount of physical effort to carry them out. Very often, these tasks are performed under adverse climatic conditions [1]. One of the higher causes of deceases in the farming sector is the overturn of tractors not equipped with a rollover protection system (ROPS) [3]. The combination of this type of protection systems, in combination with the use of a safety belt can increase, significantly, the safety of an agricultural, forestry, or industrial vehicle, in the event of overturn [5]
