Three-dimensional Modeling and Static Strength Analysis for EMU Based on Solid Works

为了计算动车组车体疲劳寿命,在分析国内外车体相关标准的基础上,提出了利用车体静强度分析和有限元分析法的高速动车组车体强度的分析方法,利用有限元分析法对CRH2型动车组车体进行疲劳强度分析,结果表明会车时车体强度满足要求,最后,利用有限元名义应力方法得出车体的疲劳强度分析图,其结果满足疲劳寿命要求,为动车组的安全运行及维护提供了理论依据。

In order to calculate the life of motor train body, a method which is utilizing the body static strength analysis and fi- nite element nominal stress method to analyze the body strength of high speed motor train unit is put forward based on analyzing domestic and international standards in body. And fatigue strength evaluation of the CRH2 motor train unit body is carried out with the help of the finite element static strength analysis, which results show that the body strength satisfy the requirements under the trains meeting; Finally, fatigue life prediction of the train body is obtained by using the finite element nominal stress method, and the results meet the requirements of the fatigue life for EMU, thus provides theory basis for safe operation and maintenance of motor train unit.
