Research on Simulation of Thermal Stability and Optimization of Drum Brakes on Toyota Innova

The brake system in a car is an important system that helps control speed and ensures safety while driving. The main function of the brake system is to slow down and stop the vehicle when necessary, ensuring the safety of the driver and other road users. In particular, the drum brake mechanism is a commonly used braking system for vehicles, in addition to competing with the disc brake mechanism. The kinetic energy of the rotating wheels is converted into frictional heat by the action of the brakes, causing the wheels to stop spinning. In this study, NX Siemens software is used to design brake drum and brake pad models, while the Ansys software is applied for detailed analysis using the finite element method. Initial simulation results provide important parameters such as temperature distribution, total heat flow, heat flow distribution, total strain, pressure, etc. Through these parameters, stress and displacement can be evaluated, forming the basis from which to infer the safety and durability of the components. Based on the obtained results, improvements will be implemented to offer a new design that is more optimal while still ensuring durability.
