“…The experimental test is then performed utilizing the aforementioned POD equipment, and the resulting frictional data are recorded once the initial verification is completed. (2) the greatest deformation occurs at the disc's outer region; and (3) the greatest frictional stress is created by the pin apparatus [30][31][32][33][34][35][36]. These findings are consistent with the overall phenomenon.…”

“…Figures 10 and 11 allow us make the following conclusions: (1) both the pin and the disc undergo linear deformation; (2) the greatest deformation occurs at the disc's outer region; and (3) the greatest frictional stress is created by the pin apparatus[30][31][32][33][34][35][36]. These findings are consistent with the overall phenomenon.…”

“…Figure 5 shows a consolidated model of the pin-on-disc test specimen created with the ANSYS Composite Preprocessor tool. The tiny red solid on top was called a pin, and the blue-grey solid on the bottom was called a disc [1,14,[21][22][23][24][25][26][27][28][29][30]. In the FEA mathematical modeling of boundary value problems, boundary conditions and governing equations play a key role.…”

In recent years, the use of unmanned aerial vehicles (UAVs) has increased significantly. Asymmetrical factors, or frictional studies on the disc brake of UAVs, are one of the safety considerations taken into consideration during the design process because UAVs and their components have been built with the best safety in mind. This study focuses on choosing the optimal material for a UAV’s disc brake by using transient structural and thermal models. In order to compare the asymmetry-based frictional force produced by the two ways; the processes used in the transient simulation are validated using pin-on-disc (POD) testing. The foundation for this validation investigation is a metal matrix composite made of an aluminum alloy, and the basis tool is an ASTM G99-based computational test specimen. Steel-EN24 and carbon ceramic matrix composites testing are expanded using the same POD tests. A range of 3 percent to 8 percent error rates is found. As a result, the calculation techniques are applied to the UAV’s disc brake after they have proven to be trustworthy. This fixed-wing UAV’s extensions have a 5 kg payload capacity. The weight, avionics components, tire dimensions, and disc brake dimensions of the other UAV design parts are calculated using analytical formulas. The final designs are made using CATIA as a result. The grid convergence experiment is organized using a traditional finite element analysis tool. Finally, at its maximum rotational speed, a UAV’s disc brake is put through asymmetrical friction testing based on structural and thermal consequences. The correct materials for critical applications, such as carbon fiber-woven-wet-based reinforced polymer and Kevlar unidirectional-49-based reinforced polymer composites for changing rotating speeds, have now been made possible by fixed-wing UAVs.

“…Acceptable output requires complete capturization. This job is difficult; thus, in order to get accurate results, the ideal mesh must be designed and tested [31][32][33][34][35]. The complete test specimen is discretized with fine structural elements, and the mesh formation on the disc's top is altered by the pin.…”

Finite element analyses (FEA) are flexible and advanced approaches, which are utilized to address difficult problems of aerospace materials that exhibit both structural symmetrical and structural asymmetrical characteristics. Frictional behavior effects are used as a crucial element in this multidisciplinary study, and other structural, thermal properties are computed using FEA. Primary lightweight materials such as glass fiber reinforced polymer (GFRP), carbon fiber reinforced polymer (CFRP), kevlar fiber reinforced polymer (KFRP), titanium alloy, tungsten carbide, steel alloys, and advanced lightweight materials, such as silicon carbide (SiC) mixer, based on aforesaid materials underwent comprehensive investigations on aircraft disc brake, two-wheeler disc brake, and ASTM general rotating test specimen (G-99). Standard boundary conditions, computational sensitivity tests, and theoretical validations were conducted because the working nature of FEA may impair output dependability. First, FEA calculations were performed on a standard rotating disc component with two separate material families at various rotational velocities such as 400 RPM, 500 RPM, 600 RPM, 800 RPM, and 10 N of external frictional force. Via tribological experiments, frictional force and deformation of FEA outcomes were validated; the experimental outcomes serve as important boundary conditions for real-time simulations. Second, verified FEA was extended to complicated real-time applications such as aircraft disc brakes and automobile disc brakes. This work confirms that composite materials possess superior properties to conventional alloys for aircraft and vehicle disc brakes.
