| Abstract: | The theoretical basis and algorithm are introduced for designing and implementing IIW(International Institute of Welding) based fatigue prediction system for railway vehicle weld structures,i.e.Palmgren-Miners' linear rule and the compution method of fatigue damage ratio.On this basis,the main function and implementation strategy of the system are presented aiming at the issues of weld joint classification and stress spectrum calculation.At last,practicability of the system is validated by calculating an en... |
