Design of Multifunctional Electric Wheel Test-Bed

This paper introduces a multifunctional electric wheel test-bed which focuses on vehicle dynamics (especially for testing the relation between tire force and slip ratio with large cornering force) and durability test of the electric wheel. On the basis of the functional requirements we propose some design specifications, with which mechanical structure and control system design as well as finite element analysis of the test-bed are conducted. The finite element analysis results show that the stress of the whole mechanism especially the critical parts is less than the yield stress limit with enough tolerance, suggesting that the test-bed meets the design specifications.
