In order to study damping characteristic and its influencing factors of E glass fiber/polyurethane composite leaf spring, we use finite element simulation method. Give a detailed research method of it: According to the structure semesters of the spring, building 3D models of composite laminate and spring and carrying out the grid division by the finite element software HYPERMESH and the mechanical property parameters of the material were given to the model; making tests of composite laminate and spring and convert the results into simulation semesters of the model; we make analysis by finite element software ABAQUS and compare the simulation results with the experimental results to find out that the mainly influence factors of composite leaf spring damping characteristic are laying angle and longitudinal tensile modulus of materials. Analysis results show that 0 angel layer damping ratio is 0.0074 belongs to small damping system. Above all, our research provides theoretical basis and research methods for studying composite leaf spring damping characteristic.
