| Abstract: | The convection thermal boundary conditions are coupled into the calculation process of solid heat conduction by Abaqus and the temperature field of cylinder head is obtained. Furthermore, two different working conditions, the preload and the gas explosion pressure thermal stress are simulated. The simulation results are helpful to find the stress concentration positions due to various factors, which can provide reference for the structure design and improvement. |
