Abstract: Aviation inertia test-bed is a kind of comprehensive simulation test equipment for testing and verifying the performance of aviation wheels and tires. During the development of the test-bed, the key design technology of the drum wheel system in the core part is studied. The drum wheel system structure is designed according to the test process and technical parameters. After analyzing the static strength of the drum wheel, the integral structure of the drum wheel is confirmed through analysis and comparison. Finally, the dynamic mechanical properties of the drum wheel are calculated. The actual test shows that the drum wheel system works reliably and stably, and realizes the predetermined test function.
