“…Figure 1 (left) shows wheel G3 mounted on a tractor. This wheel was designed and developed based on previous experiences (Cepolina et al, 2011; Naselli et al, 2013; Naselli et al, 2014); its main drawback is that due to the shape of the tread, driving on hard ground (such as asphalt or concrete) results in uncomfortable vibrations for the driver. Although remotely controlled, the vehicle on which wheels were used, can also be driven on-board to facilitate logistics.…”

“…After having tested the wheels mounted on the pendulum, considered to be an approximate representation of real conditions, the response of the wheels to explosion excitations had to be assessed also when mounted on the demining machine, that is, the agricultural tractor adapted for demining operations (Naselli et al, 2014). The machine, shown in Figure 4, is considered a light vehicle since it only weights 3000 kg.…”

This paper presents the results obtained during an experimental campaign on blast resistant wheels designed for a low-cost demining machine, derived from an agricultural tractor. Such wheels must fulfil two requirements: first, they have to be able to retain their mechanical integrity in case of blast and still work after one or more explosions, in order to be able to drive the machine out of the minefield without human intervention; second, they must reduce as much as possible the amount of energy transferred to the vehicle, to protect the on-board equipment from the effect of the detonation of a landmine. One of the goals of the experimental activity was to compare two wheels characterized by different designs. Mechanical performance and capacity of the wheels to reduce the energy transferred to the vehicle have been assessed to verify whether the wheels were suitable for the task and to identify which wheel performs best. Physical integrity of both wheels was assessed by visual inspection after each explosion. To evaluate the energy transferred to the vehicle, a measurement of the potential energy transferred, by means of a ballistic pendulum, equipped with an encoder, was performed together with a triaxial acceleration measurement in correspondence of the wheel hub. The triaxial accelerometer measurement was then also used to assess the behaviour of the wheels mounted on the vehicle after tests on the ballistic pendulum. Wheel performances have been quantified using specific features and frequency domain functions, related to the damage induced by the vibration at the interface between the hub and the demining machine. The obtained results suggest that the heaviest wheel performs better both in terms of mechanical integrity and of shock response.
