高速列车车体强度计算方法对比分析

分析国内外高速列车车体强度规范中的计算方法,以国内某型高速列车车体强度计算为例,分别采用日本、欧洲以及我国的高速列车车体强度设计规范中的计算方法,对车体强度进行计算和对比分析,并提出了一套关于车体强度评定的工程方法,为车体结构设计和强度分析提供了可靠的理论依据。结果表明:3种规范下计算得到的车体满足强度要求;欧洲设计规范考虑的载荷较为全面,我国的车体强度计算方法计算出的安全系数较大,更为保守。

Comparison and Analysis of the Calculation Methods for the Car-body Strength of High-speed Train

Based on analyzing the calculation methods of domestic and international standards for high-speed train car-body strength and taking the calculation of the high-speed train car-body strength of domestic as the example,the strength of the car-body is calculated,compared and analyzed by respectively adopting the calculation methods in the design specifications for the car-body strength of high-speed train from Japan and Europe and China.The conclusion can offer the theory guarantee for construction design and strength analysis of the high-speed car-body.The results show that the car-body strength obtained by the above three calculation methods all can meet the safety requirements.The load considered by European design specifications for the car-body strength of high-speed train is rather comprehensive,and the safety factor obtained by China calculation method of the car-body strength is greater and more conservative.
