Evaluation on Deceleration Performance of Hydraulic Hybrid Bus

分析影响缓速性能的4个主要系统参数,提出基于缓速性能的综合评价指标,包括缓速性能指标、制动能量回收率指标和系统成本指标,并分别进行科学量化。采用平方加权和理想点法构造综合评价函数,应用AMESim仿真软件对评价函数进行优化求解,获得最佳的参数组合,以达到系统成本低、缓速性能好、节油率高的综合效果。

The purpose of this paper is to evaluate the deceleration performance of hydraulic hybrid bus（HHB） fbr making thll use of tile energy-saving and deceleration fimction. Four main sbrstem parametersare proposed, which influence tile deceleration performance. Meanwhile tile integrated evaluation indexesfbr deceleration pertbrmance of HHB are proposed, which include the index ofdeceleration perlbrmance,braking energy-saving ratio and system cost. Square weighted ideal point method is employed to constructthe comprehensive evaluation function, and then this function is optimized to gain optimal parameters. The optimal results indicate every index reach the integrated effect of low system cost, good deceleration pertbrmance and high braking energy-saving ratio.
