| Abstract: |
| Under the condition of the same deflection and load at the free end,elastic beam of the rectangle equivalent section used in the pressure hose structure of hose reel irrigation is designed to meet the strength and the ratio of materials used in single beam structure and double beam structure is 11/6. |
| Key words: hose reel irrigation,pressure pipe structure,elastic beam with rectangle equivalent section,single beam,double beam,section parameter, |
