초록
To develop a high pressure main driving hydraulic cylinder for concrete pumping car, it is essential to accurately predict the internal flow structure of the hydraulic cylinder and ensure structural stability. Therefore, in this study structural and buckling analysis were essentially used for safe design. From analysis results, the maximum equivalent stress occurred when the cylinder thickness was 15 mm and the hydraulic cylinder was deemed to be structurally safe. The buckling analysis of the hydraulic cylinder assembly showed that the critical load factor was from 1.3732 to 12.021 and the critical force factor in the entire area was not observed because the critical load factor was greater than 1. The average flow rate of cylinder was uniformly distributed and the flow rate error for the inlet and outlet port could be found to be approximately identical to that of 2 %.
