针对光学遥感卫星飞轮微振动引起的成像质量下降问题,设计了一种组合隔振装置,并采用仿真分析与实验测试相结合的方法对隔振方案设计的合理性进行验证。首先,将测量的飞轮扰振数据引入光学卫星的有限元模型中,计算出飞轮扰振对光学相机的像素偏移影响;其次,设计了组合隔振方案并基于有限元方法对其隔振效果进行验证;最后,搭建了光学成像微振动实验测试平台,对不同转速下飞轮微振动造成的像素偏移影响进行精确测量。实验结果表明,组合隔振装置对300 Hz以上高频段飞轮扰振有较大衰减作用,最大像素偏移降到0.01个像素以下,隔振效率达到80%以上;通过对比可知,实验测试与仿真计算得到的像素偏移结果在低频段一次谐波响应及模态响应表现出较好一致性,但在高频段二者存在一定偏差。

Fiber reinforced cementitious composites(ECC) are a class of advanced composites with strain hardening and multiple cracking behaviors. Substitution of concrete with ECC can significantly improve the seismic resistance and durability of the infrastructures. In this paper, it is proposed to use ECC as the matrix of frame columns for improving its load carrying capacity, ductility, and avoiding the brittleness of concrete. Based on the assumption of plane remaining plane and constitutive models of materials, theoretical models for calculating the load-carrying capacity of the steel reinforced ECC columns under small and large eccentric compression are proposed. With the parameters of the constitutive models from the existing experimental data, the relationship between ultimate axial load and moment capacities is also derived with the proposed models. To verify the validity of the proposed theoretical models, finite element analysis with the software of ATENA is conducted to simulate the mechanical behavior of the steel reinforced ECC columns under eccentric compressive loading. The calculation results from the theoretical models show good consistency with the simulated results, indicating that the proposed models are feasible and reliable for design. Finally, based on the theoretical models, the effect of the ultimate tensile strain and compressive strength of ECC, longitudinal reinforcement ratio on the load carrying capacity of the steel reinforced ECC column are comprehensively studied.

Background:Eucommia ulmoides Oliv. is a medicinal plant native to China, with its bark (Eucommiae Cortex) traditionally being used for medicinal purposes. Previous research has shown that Eucommia male flowers can exert anti-inflammatory, analgesic, antibacterial, and other pharmacological effects, including immune regulation. This study explored the anti-inflammatory effects of the 70% ethanol extract of male flowers (EF) of E. ulmoides in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and LPS-administered ***:Cytotoxicity of EF for RAW 264.7 cells was investigated using Cell Counting Kit-8. The production of proinflammatory mediators, nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 was determined using enzyme-linked immunosorbent assays. IL-17, IL-23, and IL-10 mRNA levels were determined using quantitative real-time polymerase chain reaction. Activation of the nuclear factor (NF)-κB pathway in RAW 264.7 cells was investigated via Western blotting. In vivo antiinflammatory effects of EF were studied in an LPS-induced acute inflammation mouse model by analyzing lung tissue histopathology, serum TNF-α and IL-6 levels, and myeloperoxidase (MPO) activity in lung ***:EF showed no significant cytotoxicity at concentrations from 10 to 60 μg/mL (cell viability > 80%) in the CCK-8 cell viability assay. EF inhibited the RAW 264.7 cell proliferation (EF 60 μg/mL, 120 μg/mL, and 250 μg/mL vs. negative control: 87.31±2.39% vs. 100.00±2.50%, P=0.001;79.01±2.56 vs. 100.00±2.50%, Pgul
