| Abstract: | The new tank body assembly system is the critical part in special tank car manufacturing field, Its structural design and mechanical properties have direct effect on the assembly quality of tank cylinder and tank head, and consequently the operational safety. This paper carries out numerous FEA calculations on tank cylinder and inner supports, revealing the rules that parameter variations, such as cylinder thickness, diameter, number of inner supports, support offset, contact length, may cause t cylinder deformation, stress and circumferential error during the tank assembly. The paper also sets up guidelines for selecting these important design parameters, aiming at optimizing the assembly operation. |
