Evaluation of Energy-Regenerative Suspension Structure Based on Fuzzy Comprehensive Judgment (FCJ)

Abstract:

Energy regenerative suspension can transform the shock energy produced in the driving process into electrical or hydraulic energy. This paper proposes a new hydraulic electromagnetic energy regenerative suspension design, and makes a comparison with the other two energy regenerative suspension designs by studying their structures and working principles, and makes an evaluation system by using fuzzy comprehensive judgment. According to the importance of the evaluating indexes, their subjective weights are gotten by using analytical hierarchy process (AHP); according to the performance statistics data, their objective weights are gotten by using entropy method; the general weights can be gotten from the subjective and the objective ones; and the evaluating value of suspension comprehensive performance can be calculated according to the general weights and the performance statistics data of evaluating indexes. The result reveals that the hydraulic electromagnetic energy regenerative suspension design has obvious advantages and is the most feasible design.
