| Abstract: | According to the fracture phenomenon of the connecting rod in the experiment platform of the crank group
driving mechanism, the stress analysis was carried out and the design scheme of the adjustable rod for the problem was
put forward. The critical stress of the connecting rod was analyzed by using the stability theory of the press bar and the
ANSYS finite element software. The analysis results showed that the structure design of the connecting rod was not
properly designed. Finally, the design scheme was optimized, and the connecting rod was designed as an adjustable
connecting rod which was applied to the test platform. The deformation of the rod was analyzed, and the rationality of the
design was alsoverified. |
