    摘要:

    以履帶車(chē)輛靜動(dòng)液輔助制動(dòng)系統(tǒng)為研究對(duì)象,對(duì)液壓泵/馬達(dá)的性能進(jìn)行了理論和數(shù)值分析,,獲得了液壓泵/馬達(dá)的效率曲線(xiàn),,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(dòng)控制策略,。仿真結(jié)果表明,,所提出的再生制動(dòng)控制策略,,在保證整車(chē)安全制動(dòng)的前提下,使液壓泵/馬達(dá)工作在高效率區(qū),,實(shí)現(xiàn)了液壓泵/馬達(dá)的高效率工作,,可進(jìn)一步提高整車(chē)制動(dòng)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.
