| Abstract: | On the basis of the actual measurement of the whole stress-time course at the relief grooves of axles for passenger cars,the stress spectrum is obtained after the rain-flow counting;The load calculation is made with the finite element method and the load spectrum is obtained;And the load distribution features and regulations are analyzed with the reliability theory. |
