The Stability of Hydraulic Cylinder Calculated bythe Second Order Elastic Analysis |
| |
| Abstract: | Hydraulic cylinder is the critical operator in the hydraulic system of various machine. This paper provides the comparison between the traditional methods and the second order elastic analysis with one typical example. The conclusion indicates that the buckling analysis by the second order elastic analysis is more accurate and shall be widely used for future design and stability of cylinder. |
