| Current and future period of time, the trend of world peace and development will not change the overall international situation stabilized, but the impact of world peace and development, uncertainties still exist. In this case, how to strengthen China's national defense building and improving the ability of anti-terrorism became a national security priority. Blast the present study engineering structures has become an important engineering issue, this paper developed by a research institute a new aluminum trailer, analyze and discuss the impact load in the explosion of dynamic effects.In this paper, the characteristics of aluminum camping trailer and the use of the operating conditions, the finite element method was composed of houses were on the whole the basic component beams and columns in the ideal state and the initial defect state, the blast load on the housing or components dynamic response analysis. Obtained activity board room of the beams, columns, and the overall framework under blast loading unit in the maximum displacement and maximum stress, and simplified according to the dynamic theory of beams, columns and the skeleton structure of the overall study, draw the beam, column, the overall frame structure, the deflection versus time curve. And has been able to prevent the housing collapse and the destruction of the security required and the equivalent distance of components under blast loading the weak link, while analysis also showed that housing defects in the blast loads on structures, but it can be ignored.In this paper, by the blast load beams, columns and the overall structure of the dynamic response of the theoretical analysis and numerical simulation, some conclusions and results obtained for the structure subjected to explosive loads analysis provides a theoretical basis. |
