@Udin how did you apply the load?? And i recommend you to go for a static analysis with maximum load and evaluate the stress under static condition for maximum magnitude of load. You can also evaluate the signed von mises stress and evaluate the mean and alternating stresses.

The load i create myself and i took from the applied load of the centre leaf spring which is 9810N. I should take the von mises stress as my load? ohh i see we need to find the mean stress from signed von mises?

okay thats means i need to change from 1600kg into tonne=1.6 then convert it into Newton=15.696N. is it? if i use this value my vonMises is 7.99E+1 but the fatigue life is still small value which is 0.04.

thts means its starts from solidworks unit scale ? if in solidworks i set to mm , than i need to use the ton,mm,s,N,Mpa, Demsity = 7.83e-9 , Young's = 2.07e+5 , Gravity = 9.806e+3 ?
