    摘要:

    以履帶車輛靜動液輔助制動系統(tǒng)為研究對象,對液壓泵/馬達(dá)的性能進行了理論和數(shù)值分析,獲得了液壓泵/馬達(dá)的效率曲線,在此基礎(chǔ)上,根據(jù)液壓泵/馬達(dá)的效率最優(yōu)原則,提出了基于液壓泵/馬達(dá)效率最優(yōu)的再生制動控制策略。仿真結(jié)果表明,所提出的再生制動控制策略,在保證整車安全制動的前提下,使液壓泵/馬達(dá)工作在高效率區(qū),實現(xiàn)了液壓泵/馬達(dá)的高效率工作,可進一步提高整車制動能量回收率。

    Abstract:

    Based on the hydrostatic and hydraulic auxiliary braking system of tracked vehicle, the hydraulic pump/motor efficiency model according to hydraulic pump/motor performance analysis was set up. The optimal working line in which the hydraulic pump/motor worked at the highest efficiency level was obtained. An energy regenerative braking control strategy was proposed which could lead to the optimal matching of hydraulic coupler, hydraulic pump/motor. The simulation and test results showed that the hydraulic pump/motor could achieve efficient operation, and the energy regeneration efficiency of braking was improved obviously with the regenerative braking control strategy under the safe braking conditions.
