| 摘 要： | 为从理论上揭示插装阀组集成控制液压系统瞬时失效的原因,以混凝土泵液压系统为例,提出了基于流体逻辑理论的插装阀组启闭状态组合的解析方法,并运用混凝土泵液压系统的数字化模型验证其有效性.研究结果表明,当负载处于一定范围时,个别插装阀的不当开启会导致不同插装阀的容腔短暂串通,造成液压系统的瞬时失效,而增加插装阀控制腔压力可以...

| Abstract: | To theoretically reveal the reasons for instan-taneous failure of cartridge valves in integrated control hydraulic system,concrete pump hydraulic system was taken as an example,an analytical method of cartridge valve's on and off states combination based on fluid logic theory was proposed.And this method was testified by the digital model of concrete pumrp hydraulic system.The research result shows that within a certain range of load,an improper opening of single cartridge valve will cause connectivity betw... |
