| Abstract: | Providing a new method for calculating autofrettage pressure of CNG2 type cylinder that is based on buckling strength and buckling ratio of material of the cylinder liner, used the characteristics of FEA that can accurately calculate the tension of every part in CNG2 type cylinder. Opening up a new path that accurately calculate autofrettage pressure and guide the production of CNG2 type cylinder quickly. |
