RESEARCH ON ACCELERATED LOAD SPECTRUM FOR FATIGUE TEST OF PHEV SUBFRAME WELDS

Aiming at the problem of the weld fatigue test of the new energy vehicle subframe, a program load spectrum compilation method based on the failure dominant load was proposed. Firstly, the finite element model of the rear subframe was established, and the stress distribution under unit load was coupl...
