“…Polymerization is one of the most common methods to incorporate CNTs into a polymer matrix. The behavior of a burdened tire during its deformation is difficult due to the united contributions of the structural components of tread rubber and the air contained within it (Anifantis, Cutini, and Bietresato 2020) [5] . The safety and durability of tires can be improved by adding appropriate nanoparticles in rubber composites (Alkhazraji 2018) [4] .…”

Agriculture as a source of food is becoming increasingly important in a world of diminishing resources and an ever-increasing global population. It is necessary to utilize future ready solutions like nanotechnology to increase global food production, enhance food quality, and reduce waste for sustainable intensification. The potential uses and benefits of nanotechnology are enormous. Productivity enhancement through nanotechnology-driven precision farming and maximization of output and minimization of inputs through better monitoring and targeted action is desirable. Nanotechnology is the creation of devices and machines on an atomic level which will be a driving force for the next generation. Nano can be technically defined as manipulation of matter with at one dimension sized from 1 to 100 nanometers (0.000000001 m). The nanotechnology revolution had a ground-breaking impact in multidisciplinary fields, and there are likely to be considerable advantages in the field of agricultural engineering in the near future. Nanotechnology is expected to have a massive impact on the world food supply chain. It was found that nanotechnology can impact so many areas of farm machinery, and it has created a more significant impact on the manufacturing and service sectors. The recent advances in nanotechnology-based tools and techniques can address the various problems of conventional agriculture and can revolutionize the industry. In the present scenario, Nanotechnology is used in the manufacturing of agricultural equipment, production of nano-polymer composites, metal nanocomposites, paints, resistivity coatings in machinery, sensors used for precision farming, and lubricants.

“…10), the pressure sensors to measure the instant inflation pressure of the vehicle so as to modify accordingly the rollover safety limits for that vehicle after the execution of some tests at this installation. This phenomenon is very interesting because it has two main effects on the vehicle stability, both complex and dangerous: on the one hand, it surely increases the inclination of the chassis and shifts the CoG down the slope [34], on the other hand, it modifies the width of the support polygon due to the associated lateral lying down of the downstream tyre [35]. Therefore, the maximum guard angle (i.e.…”

“…Consequently, the residual safety margin at rollover in various slope and tyres inflation situations can also be determined. The lower the tyres inflation pressure, the lower the corresponding equivalent elastic constant (thus including both the carcass and the inflation air [34]) and the greater the tyres compliance with load transfers.…”

The stability of a vehicle (especially if operating off-road, such as a farm tractor, possibly with an implement attached) can be statically investigated by means of a test installation such as the one described here. It consists of a platform (dimensions: 6.42 × 4.46 m) having two degrees of freedom (inclination, rotation) and on which the vehicle is positioned motionless. By acting on these degrees of freedom, it is possible to precisely and simultaneously control all the characteristic angles of a vehicle (roll, pitch, yaw), thus discovering, in complete safety, its operational limits (i.e. its incipient rollover conditions). Furthermore, the ability to misalign up to two of the four quadrants composing the platform allows the testing of further critical situations for the vehicle, in which the front-axle pivot joint and the tyres elasticity are involved, potentially up to a scenario in which the vehicle rests on only three of its four supports and its support polygon degenerates into a triangle. The basic test scenarios that can be investigated with this installation allow the study of many aspects of a vehicle, pertaining both to the general chassis performance of the vehicle (therefore related to its balance) and to the load state of some specific components (internal or interfacing the vehicle with the outside, e.g. the wheels). The obtained data, referred to reference test scenarios, allow the experimenters to: (1) interpret sensors readings in real operating situations, thus including also the contribution of the tyres vertical flattening and lateral deflection, (2) complete the safety documentation at the users' disposal with some specific graphs, the vehicle 'equilibrium maps' (or 'stability charts'), possibly referred also to the vehicle with some accessories/implements connected to it. By demonstrating the undeniable usefulness of such an installation, the authors hope to propose new testing paradigms with the ultimate aim of increasing the overall safety of vehicles and, particularly, of agricultural and work machinery.

“…Moreover, the deformability of the tires plays a fundamental role in vehicle stability in terms of side rollover. The behavior of a loaded tire during its deformation is complex, due to the combined contributions of the structure components, the tread rubber and the air contained within it (Anifantis, Cutini, and Bietresato 2020).…”

Agriculture sector is one of the social, economic elements and indicators of sustainable development in any country, investigating the impact of the introduction of new technologies such as nanotechnology into this sector is of particular importance. In recent years, some research has appeared studying the effect of using nanomaterials as an alternative solution in the field of power and farm machinery on improving the performance of agricultural equipment. This review covers the current applications and challenges that are exploring by the researchers in the area of nanotechnology in improving the production of construction materials and agricultural equipment coatings, such as coatings that are resistant to sunlight and wear in machinery, sensors for increased precision and performance, machinery tires, microprocessors, lubricants, Coolants, and soil conditioners , ultimately, the impact of this technology on improving the performance of agricultural equipment. Finally, it can be concluded that nanotechnology is an essential axis in the development of the power and farm machinery sector. Therefore, we recommend more research to study and suggest a solution for challenges facing the use of this technology and to work on transforming research results into productive projects to link research with investors
