Bogie frame and body bolster are of vital importance to the reliable operation of the rolling stocks. There are two kinds of test methods for bogie frame and body bolster. One is separate test, and the other is joint test. To effectively detect the strength performance of bogie frame and body bolster as well as to improve the test efficiency, we adopted the method of joint test, and designed the test plan according to the standard. The strength test of bogie frame and body bolster is carried out where load analysis is studied and applied. The structural performance of bogie frame and body bolster is evaluated by means of Goodman fatigue limit diagram.
