| Abstract: | The calculation theory and the analysis process of the DDAM are introduced in the paper,with the relative rules of the shock design spectrum of both the British system-based US military standards and the international unit-based military standards used by our army dealt with.Through the investigation of both the calculation theory and process of the ANSYS,the international unit-based input method of the DDAM response spectrum analysis of the ANSYS is put forward in the paper,which breaks through the limitation of the British system of units in analysis and serves as a useful reference to the shock analysis of shipboard equipments in our country. |
