1汽车动力系离合器接合抖振和粘一滑的分析和仿真显示文摘研究分析了离合器接合的抖振和粘一滑以及用数字来检验这些现象的影响系数。为具有汽车变速箱装置的动力系带打滑离合的4自由度(4DOF)的扭振系统开发了一个模型。进行稳态分析表明该离合器的抖振与摩擦系数和斜率有关,并用数字仿真加以证实。开发了模拟粘一滑的一种算法,并用于数字仿真,它表明了由于离合器压力波动,离开接合的抖振和外载荷变动将增加了粘一滑的可能性。由2档换到3档的数字仿真证明,根据离合器接合时作用压力波动,离开接合抖振和外载荷波动发生粘一滑可能增大,而随作用压力倾斜到啮合点发生粘一滑可能性明显减少。A.

2鱼、蛋、牛奶、坚果、蔬菜和水果摄入量大,以及低盐膳食模式与高血压的患病率和控制率相关显示文摘食物对高血压患病率和控制率的影响尚不清晰。本文旨在中国人群中调查鱼、蛋、牛奶、坚果、蔬菜和水果摄入量大以及低盐膳食模式是否与高血压有关。方法:从2012年9月到2014年12月共招募15303名受试者进行病例对照研究,分为高血压组(n=1604)和正常血压组(n=13660),其中高血压组又分为血压控制亚组(n=397)和血压未控制亚组(n=1207)。收集过去1 年里每周平均鱼、蛋、牛奶、坚果、蔬菜、水果和盐摄入量数据。鱼、蛋、牛奶、坚果、蔬菜、水果和盐的平均摄入量分别为117、150、35、20、2100、300和58g/周。Yu G Fu H Huang W Zhang N Deng D Li G Lei H 2019中华高血压杂志2019,27,5:2
