【摘要】 用有限元方法对TGN30A型静止逆变器(SIV)在冲击过程中的受力情况进行了分析计算,同时探索了冲击过程中结构本身的动特性因素对应力变化曲线的影响,运用动力学分析方法模拟冲击实验过程中应力值的变化,使仿真分析更接近实际情况,提高了分析的准确性。更多还原

【Abstract】 Finite element method is adopted to analyze the force situation of TGN30A type SIV in impact.Meanwhile,it researches the effect of structure dynamic characteristic to the stress curve in the process of impact.For the purpose of making the simulation analysis close to the reality and improving the accuracy of analysis,dynamics analysis method is used to simulate the change of stress values in shock test.更多还原
