采用Pro/E对散热器进行几何建模，将模型导入Hypermesh进行几何清理、网格划分等，建立有限元模型；将模型导入Nastran中进行模态分析，得到散热器在水压0．28 MPa下前三阶模态振型。将前三阶共振频率与试验值相比较，验证了仿真结果的准确性。针对分析对薄弱部分提出改进措施，对散热器进一步改进提供了重要参考。

The model of the radiator is made with Pro/E and is imported into the Hypermesh.Then the geometric cleaning, meshing , etc are made in the Hypermesh, and the finite element modeling is completed;The model is analyzed with the Nas-tran and the vibration mode of the top 3 order modal analysis under the water pressure of 0.28 MPa is obtained.The frequen-cies are compared to the excitation frequency , the accuracy of the simulation results areverified .Through analysis the im-provement measures are proposed for weak part, which provides an important reference on the radiator for further improvement in theory.
