以滚滑轴承为研究对象,运用ABAQUS有限元仿真分析软件,建立了轴承的有限元分析计算模型,并对其弹性接触状态下的动力学问题进行了仿真分析,得到了轴承各零件最大应力的分布及其动态变化规律。结果表明有限元法能够精确的求解滚滑轴承动力学问题,在稳定工况下,滑块与内、外圈接触的表面应力最大,内、外圈表面的应力次之,圆柱滚子表面的应力最小。其中滑块承受了较大部分的载荷,有效地降低了滚子表面的接触应力,且滑块与滚子之间的协调性良好。

Some studies have confirmed the neuroprotective effect of remote ischemic conditioning against stroke. Although numerous animal researches have shown that the neuroprotective effect of remote ischemic conditioning may be related to neuroinflammation, cellular immunity, apoptosis, and autophagy, the exact underlying molecular mechanisms are unclear. This review summarizes the current status of different types of remote ischemic conditioning methods in animal and clinical studies and analyzes their commonalities and differences in neuroprotective mechanisms and signaling pathways. Remote ischemic conditioning has emerged as a potential therapeutic approach for improving stroke-induced brain injury owing to its simplicity, non-invasiveness, safety, and patient tolerability. Different forms of remote ischemic conditioning exhibit distinct intervention patterns, timing, and application range. Mechanistically, remote ischemic conditioning can exert neuroprotective effects by activating the Notch1/phosphatidylinositol 3-kinase/Akt signaling pathway, improving cerebral perfusion, suppressing neuroinflammation, inhibiting cell apoptosis, activating autophagy, and promoting neural regeneration. While remote ischemic conditioning has shown potential in improving stroke outcomes, its full clinical translation has not yet been achieved.
