Flexible Modeling and Dynamic Design of the Auto Jack

For evaluating the stress state of the jack more precise, the technology of flexible modeling was applied to structure design of the jack. The simulation model with rigid body of the components were set up by AutoFlex module, and the jack’s dynamic curves in static loads were acquired through flexible simulation, then the dynamic characteristic and stress state of the jack which in working process was understand. Based on that, some basis was offered for improvement and reliability design of the jack.
