Abstract
The reconfigurable wheel-track transformation mechanism is characterized by short conversion time and excellent terrain adapability, appropriately resolving the contradiction between trafficability and mobility. Based on a new transmission scheme, this paper focuses on the mechanical properties of its transformation mechanism, so as to provide theoretical support for structure optimization. The mechanical model is established by analyzing the forces of key components during the process of transformation, after which stress and strain of them is analyzed through finite element analysis software, according to previous calculations from the model. The results show that parts with direct contact with ground bear more forces than others. Maximum stress of parts is within the limit strength of materials, but structure of weaker parts should be further improved to reduce stress concentration.
