利用大型通用有限元软件ANSYS对高速电力机车SS8型转向架构架在垂向静载工况、曲线通过牵引工况和曲线通过紧急制动3种工况下的静强度进行了分析,得出了相应各个部位的应力和变形.分析表明:转向架在3种工况下其最大变形仅为0.58 mm,最大应力为62.26 MPa,小于16Mn钢的屈服极限350 MPa和强度极限520 MPa,符合设计要求.这些计算数值为进一步研究转向架的动态特性、设计和优化提供了理论基础.
The static strength of SS8 bogie frame for high speed electric locomotive under vertical static load condition, the curve passing traction condition and the curve passing through emergency braking are analyzed by using the large general finite element software ANSYS. The corresponding parts of the stress and deformation analysis shows that: the bogie under the three conditions of its maximum deformation of only 0.58 mm, the maximum stress of 62.26 MPa, less than the yield strength of 16Mn steel 350 MPa and the strength limit of 520 MPa, in line with the design requirements These calculated values provide the theoretical basis for further research on the dynamic characteristics, design and optimization of bogies.
