The Study of Fail-Safety Mechanism in Cylinder Design

Abstract:

In this study, the hydraulic cylinder with internal non-slip safety locking device was designed and analyzed. From the market demand and fail-safety requirement, the hydraulic cylinder prototype specifications are developed. The dimensions and mechanisms of hydraulic cylinder model were initially designed to make sure parts combination as requirement. The stress and deformation of designed model with material properties were analyzed by Solidwork COSMOS module. The finite element analysis results showed that the clamp clip cutting seams help to uniform rod and clamp clip stress distribution. The bottom end and front end of the clamp clip with 16 cuttings have the best results in terms of stress and deformation. But the bottom end and front end of the clamp clip with 8 cuttings for rod holding effect would be better for reducing machining costs and increase durability. The stress concentration phenomenon of cut clip end can be rounded treatment; in order to reduce stress is too large in clip end.
