| Abstract: | The models for temperature field and stress field of tank exhaust-valve insert under working conditions are set up based on the theories of elasto-plasticity and heat transfer, both distributing states and change regulations of its thermal stress and mechanical stress are researched by means of non-linear FEA. Theoretical bases for the studies on its selections of materials and optimizations of structure are given. |
