Simulated analysis for oil-tank of main transformer on type SS9 electric locomotive |
| |
Abstract: | The new type of lower posited oil-tank of main transformer on type SS 9 electric locomotive is a compli-cated spatial structure with combination of plates and sticks.In this paper,using the finite element method,the main transformer of SS 9 electric locomotive under various load conditions including lifting,test and running process is an a-lyzed.Stress and displacement of oil-tank are obtained,providing a reference to practical improvements on structure. |
