摘要

为了改善蓄能器的动态特性,保证其稳健性,该文利用AMESim软件建立了液压制动系统的模型.运用Optimization工具,以蓄能器在紧急制动工况可保证的制动次数为目标,利用遗传算法对影响蓄能器的主要设计参数进行了优化,得到最佳充气压力为6 MPa,并验证了其稳健性,为蓄能器与整个制动系统匹配设计提供了方法和理论依据.该研究对于蓄能器的优化设计和改进具有参考作用.%For improving the dynamic characteristic of accumulator and ensuring its robustness, the model of hydraulic braking system was developed by using AMESim. The brake number was taken as the optimization target, and the optimization tool was applied. The gas precharge pressure of accumulator was optimized using the genetic algorithms. The best inflation pressure was 6MPa, and the robustness of accumulator was verified. The research results provided the methodological and theoretic basis for match design of accumulator, which offers an important reference for improvement and optimization design of the accumulator.
