【Abstract】 Based on the ANSYS Parametric Design Language of Finite Element Method( FEM) theory the parametric model and the modal analysis of the gas cooler are conducted. The results show that the modal analysis of gas cooler can be realized parametrically and automatically. Comparing this simulation results with the experimental results, it shows that the critical frequencies of simulation results are coincident relatively well with those of the experimental results, which making improvement in the pre-design of gas cooler structure regarding its dynamic characteristics.更多还原
