High-speed radio-controlled cars often experience a loss of vehicle control due to mechanical wheel failure, which can result in significant material damage and pose safety risks. Therefore, understanding the operational limits of the wheels is essential for reducing cost-related risks and ensuring safety.
For this purpose, a test device was designed as part of the final project to evaluate the burst behavior of model wheels under various combinations of radial and traction loading. During the design process, it was determined that simulating the ground using an external drum configuration is the most suitable approach for model wheels. The radial load was applied via a transmission mechanism using weights, while the traction load was generated by braking the drum based on the friction principle. Maintaining a high level of consistency for the latter proved more challenging. Computational analysis revealed the occurrence of high eccentrically induced loads during wheel burst, which necessitated optimization of the geometry of the designed components.
