【 摘 要 】

Finite element technology provides the basis for the complex structural analysis and calculation, which has been widely used in the design and evaluation of large-scale equipment. However, the time and cost of calculations are getting larger and larger due to complexity of the structure. How to improve the economics and rationality of calculations as much as possible under the premise of ensuring accuracy has become the focus of research. In this paper, the simplified high-pressure heater is taken as the research object, and the influence of different grid size on the calculation accuracy is shown. It is shown that the mesh size could be appropriately increased under the premise of the certain calculation accuracy, which could improve the calculation process and shorten the calculation time.
