At first, the working principle of shock absorber on energy dissipation characteristics was introduced , and three evaluation indexes on energy dissipation performance of shock absorber were put forward,including total energy of indicator, energy ratio and plumpness.Based on LabVIEW platform, the energy characteristic curve programming of shock absorber was realized . The energy characteristic curve of shock absorber was obtained by applying different incentive speed on shock absorber，and the evaluation indexes on energy dissipation of shock absorber were proposed to analyze the characteristics of energy. The results show that the energy curve gradient of shock absorber is affected by the valve opening and the distortion of shock absorber, and the evaluation index on energy dissipation performance can be used to evaluate the energy characteristics of shock absorber.
