“…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.…”

“…The disc is modeled to rotate in the direction of the "Z" axis, so a remote displacement is applied in that direction. As "3D" structural elements are used to create the grid, each element must be solved using a stiffness-based dynamic approach and 15 governing equations [14,[31][32][33][34][35][36][37][38][39][40][41]. this computational model.…”

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.

“…In order to slow down an in motion system, brakes absorb its kinetic energy, often via friction. It may be applied to a moving vehicle's axle, wheels, etc., to reduce their speed or cause them to stop [1]. Although its operation may seem simple, the braking system is really a complex apparatus with many moving components.…”

“An object remains in its state of rest or in motion until and unless acted upon by an external force” Newton’s first law of motion, Braking systems were made possible by this rule of Sir Isaac Newton, which states that the greater the vehicle’s speed, the greater the brake force needed to slow it down. This idea spawned several studies in the subject of braking, leading to its development, which in turn has given us the luxury of picking the most effective braking system for any given situation. This research analyses the thermomechanical behaviour of dry disc-to-pad contact during braking using Finite Element Analysis (FEA). Air ventilation and friction will be increased by modulating the design for disc heating issue due to long life of brake disc. The modeling of transient disc brake temperature is used to determine the disc’s geometric design for vehicle ventilation. The thermal-structural analysis is coupled to calculate disc deformation, Von Mises stress, as well as pad contact temperature distribution. The findings match the specialist literature.
