Rheological behavior’s effect on the work performance of oil film

A 3D model of hydrostatic turntable’s oil chamber is established to investigate the lubricants performance with different rheological properties by using FLUENT software and the finite volume method. Newtonian oil and non-Newtonian oil’s performance under varied speeds are compared on the large size hydrostatic turntable system considering the temperature-viscosity relationship and pressure-viscosity relationship. The results show that the property of non-Newtonian fluid viscosity influenced by shear rate largely affects the lubricants performance for most oil added polymer additives. Lubricants cannot simply be regarded as Newtonian fluid. The shear thickening non-Newtonian fluid has a better work property. The results are important to design a large size and high-speed hydrostatic support system, choose lubricant oils, and investigate oil film’s work properties.

Traces and echoes of De Architectura by Marcus Vitruvius Pollio in the work of Xu Guangqi in 17th

This study aims to investigate the role played by Xu Guangqi (1562–1633), minister of the Ming Dynasty, in the development of European scientific and technical knowledge in China between the 16th and 17th centuries by analyzing a book of Western technology that he wrote, namely, Taixi Shuifa (On Western Hydraulics). Several Western books related to machine knowledge are searched to trace the source of the illustrations in Taixi Shuifa. We found that Archimedes’ screw and Ctesibius’ machine, which are included in Vitruvius’ De Architectura volumes, also appear in the work of Xu Guangqi.

为提高液压挖掘机工作装置动态性能的优化效率,在对该结构进行试验模态研究的基础上,用双模态空间动力修改方法进行了动力特性修改研究,研究结果表明:质量修改对该结构的1阶、2阶固有频率和阻尼比有显著影响,对其他阶结构动态特性的影响很小;刚度修改对该结构1阶至5阶的固有频率和阻尼比均有明显影响,高阶的固有频率和阻尼比对刚度的变化敏感。所得到的结论揭示了模态参数调整对液压挖掘机工作装置动力特性的影响规律,为提高机械产品的总体质量奠定了基础。
