| Abstract: | The steady thermal transfer and thermal stresses of the structures of a 3800DWT chemical tanker are analyzed based on the software ANSYS.In this paper,3D finite element mode of the chemical tanker is created.The steady temperature field of the full load case is obtained using the computer program by the finite element method,and based on the thermal results,the structural stresses are calculated.Finally,the structural thermal stresses are compared as load different temperature liquid cargo. |

| Keywords: | chemical tanker temperature field thermal stress |
