Recently, the increasing vibration isolation demands drove the interest of viscous damper development towards employing non-Newtonian fluids that allow tailoring of highly customized damper characteristics. Several attempts have been made for using shear-thickening fluids; however, most of these studies measured only the final, resulting damping characteristic for a particular fluid rheology. This paper aims to give an analytical technique to predict the damping characteristic in the case of arbitrary fluid rheology for piston-type damper geometries with either an annular gap or circular hole(s) as restriction elements. The flow is approximated by laminar Poiseuille flow, and the governing equations are solved for arbitrary rheology. We present several force-velocity example characteristics for general rheologies, compare the analytical estimations against CFD computations, and provide a sample computation for nonlinear damper design.

近来，隔振需求的增加驱使对粘性阻尼器的开发兴趣转向采用允许定制高度定制的阻尼器特性的非牛顿流体。为了使用增稠剪切液，已经进行了几次尝试。但是，大多数这些研究仅测量了特定流体流变学的最终最终阻尼特性。本文旨在提供一种分析技术，以预测在环形间隙或圆形孔作为限制元件的活塞型阻尼器几何形状的任意流体流变情况下的阻尼特性。用层流泊瓦流动近似该流动，并求解任意流变学的控制方程。我们提供了一般流变学的几个力-速度示例特性，
