The Original Brake pedal weight was 697 grams. Used as a baseline for comparison. Reference models 1-3 achieve savings weight 41, 85, and 51 grams, respectively. Weight has dropped significantly from 119 grams to 212 grams. Additionally, the safety factors of the original and optimized models were evaluated, while optimized models could have safety factors ranging from exceeding to meeting the industry standards. These results explicitly show the criteria of topology optimization for optimizing weight via placing the brake pedal in the right position while ensuring its safety and structural integrity. Successful application of these techniques improves the design and optimization of lightweight and highperformance automotive components
with certain conditions and parameters, so that the most optimal solution can be obtained. Hence, simulation in virtual environments serves AS a platform for the discovery of new and unconventional design developments that may have been excluded by traditional methods. Here we are going forward and presenting a strategy for the creation and mass topology optimization of a brake pedal using the topology optimization technologies. The goal is to create an optimum weighing and strengthening brake pedal design scheme without increasing mass while meeting or overshooting the performance criteria. The proposed methodology harmoniously combines simulation trials involving topology optimization algorithms and experimental studies to conclude that the approach gives positive results and boosts braking pedal efficiency.
Key Words: Topology Optimization, Brake Pedal, Mass Reduction, Safety Factor, Finite Element Analysis.
1.2: Brake pedal innovation in design. The only of the braking system in a car is to slow the speed of moving down by pressing the brake pedal, as the brake pads press/rub against the rotor/friction. The simple task of the brake pedal is to commute the driver's feet power into the braking machine, and this has not been improved for years, contradicting the environment and increasing the cost. This work is made up of the effort to lose the whole weight of the pedals and to achieve a lightweight and beautiful design through Topology Optimization. The pedal ratio, which equals the space from the fulcrum to the pedal’s center to the distance to the master cylinder attachment point, is of the utmost importance.
1. Introduction The automotive component engineering, especially, the safety-focused parts design like the brake pedal, undoubtedly, takes crucial roles in vehicle operation safety and performance. The brake pedal acts as a mechanical linker between the driver and the vehicle braking system, transferring driver input force to the braking system to actuate the brake. To wrap up, the good design of the brake pedal is vital for functionality, efficiency, as well as better vehicle performance. Normally, particular examples of designing car components use the method of iterative and many corrections based on the expertise of engineers. While these methods have succeeded in the production of effective designs, the possibility that their full weight-saving potential or structural efficiency could be attained is still unlikely. Besides, the managers tend to design vehicles with lesser weight so that they can have better fuel efficiency and low emissions as well. Therefore, these innovative design techniques were invented to create light structures with optimal functionality while keeping to the minimal mass at the same time. Topology optimization, the late, computationally wise technique, has allowed designs with material redistribution within a space of a given design to be optimally produced. By approximating the design problem as an optimization task, topology optimization techniques are
