| Abstract: | Taking the one-piece thin-wall nodular cast iron piston in 16V240ZJ diesel engine as an example,de- termines its thermal boundary conditions with two-segments temperature-fitting,and obtains the three-dimensions steady state temperature field for this piston;taking this temperature field as thermal load, calcualtes its thermal deformation and thermal stress,gives some significance conclusions. |
