Abstract In order to speed up the application of composite leaf spring in automobile lightweight process, the performance test of anisotropic composite leaf spring is particularly important, and the dynamic fatigue performance directly reflects the reliability of composite leaf spring in practical use. At present, the fatigue performance test of composite leaf spring basically stays in the vertical fatigue, and there are few reports on the test research of braking and steering dynamic fatigue that often occurs in the actual use process. In this work, the vertical, braking and turning fatigue test methods are designed for the composite leaf spring under different working conditions. The stiffness, maximum bearing capacity, braking condition, steering condition and different dynamic fatigue are studied by finite element analysis method. At the same time, the reliability of the finite element analysis model is verified by the static load stiffness, maximum bearing capacity and vertical dynamic fatigue test of the composite leaf spring. Finally, limiting the fatigue life and the allowable stress value of the composite leaf spring, the vertical fatigue limit load of the leaf spring is 1.5 times of the vertical full load. The braking fatigue limit load is 1.5 times full load in vertical direction and 1.5 times full load in length direction. Steering fatigue limit load is full load in vertical direction and 0.8 times full load in lateral direction.
