| Abstract: | To determine the dynamic properties of a MLRS,the three-dimensional CAD model of the system was created in Pro/E and then the former was introduced into ANSYS,in which it created the particular finite element model of the system and the modal natural frequencies and vibration mode were obtained.The results are very useful for optimal design. |
