为解决车辆主动悬架系统减振效果与控制能耗间的矛盾,基于“数字孪生、以虚控实、节能减振”理念,提出了主动空气悬架系统的理想孪生动挠度跟踪控制策略。首先,以车辆座椅主动空气悬架系统为例,利用准零刚度系统构建了真实空气悬架系统的理想数字孪生体,同时建立了该孪生体的参数匹配设计方法;然后,以空气弹簧气体压力控制为节点,设计了外环位置模糊非奇异快速终端滑模控制器,以及考虑空气弹簧充放气过程中电磁阀非线性流量特性的内环气压控制器,进而实现真实悬架系统对实际激励下孪生体动挠度的跟踪;最后,通过台架模拟实验与整车平顺性仿真实验,对所提控制策略的有效性与先进性进行了验证。结果表明:与以降低加速度为控制目标的传统控制策略相比,所提策略在随机路况下的座椅垂向振动加速度均方根更小且控制能耗均方根最小降幅达65.0%,冲击路况下座椅垂向振动剂量也更小且主动控制力最大降幅高达45.5%。所提策略性能明显优于传统策略,能在有效提高悬架系统减振性能的同时大幅降低主动控制能耗,有效解决了上述矛盾,可推广应用于各类主动悬架系统,为节能减振提供新的研究思路。

Huang S, Zhang A, ding g, Chen R. Aldosterone-induced mesangial cell proliferation is mediated by EgF receptor transactivation. Am J Physiol Renal Physiol 296: F1323-F1333, 2009. First published April 1, 2009; doi: 10.1152 / ajprenal. 90428.2008. -Aldosterone (Aldo) stimulates glomerular mesangial cell (MC) proliferation, in part, through an ERK1 / 2-dependent pathway. In this study, we examined whether Aldo activation of ERK1 / 2 in MC is mediated through redox-dependent EgF receptor (EgFR) transactivation, as well as the involvement of other signaling mechanisms in Aldo-induced MC proliferation. Aldo increased human MC proliferation, as determined by [H-3]thymidine incorporation and cell counts. This increase in proliferation was blocked by inhibition of the mineralocorticoid receptor (MR). Continuing our observations downstream in the signaling pathway, we examined the ability of Aldo to activate both the Ras / MAPK and the PI3K signaling pathways. Aldo increased Ki-RasA and Ki-RasA:gTP levels, and sequentially phosphorylated c-Raf, MAPK kinase (MEK1 / 2), and ERK1 / 2. Ki-RasA small interfering RNA (siRNA), the c-Raf inhibitor gW5074, and the MEK1 / 2 inhibitor PD98059 reduced Aldo-induced cell proliferation by similar to 65%. Aldo also increased phosphorylation of PI3K, Akt, the mammalian target of rapamycin (mTOR), and the 70-kDa ribosomal S6 kinase (p70S6K1). Inhibition of the PI3K pathways by the selective PI3K inhibitor LY 294002, an Akt inhibitor, or the mTOR inhibitor rapamycin reduced cell proliferation by 51% . Combining LY 294002 and PD98059 completely blocked Aldo-induced MC proliferation. Next, we confirmed that Aldo exerts its effect on MAPK and PI3K activation, as well as on cell proliferation, by activating the EgFR. Pretreatment with the EgFR antagonist Ag1478 inhibited MC proliferation, as well as the activation of Ras / MAPK and PI3K / Akt, suggesting that Ras / MAPK and PI3K / Akt activation occur downstream of EgFR activation. Finally, we exa
