Initial Discussion of Feasibility of 35-Year Safe Operation of Zhuan K6 Bogie Bosters

The structural differences between bosters of Zhuan K6 bogies and the original Zhuan 8A bogies are compared.The finite element analysis for the static strength is made.The stress levels are compared.And the fatigue damage of the two types of bogies are analyzed.Furthermore,the feasibility of application of Zhuan K6 bogie bolsters for 35-year is discussed.
