annular passage meaning in Chinese

环形通道

According to the working modes of mr devices , combining the ohm ' s law of magnetic circuit and the design theory of non - steady magnetic circuit , magnetic structures of the automotive damper have been worked out . to emulate the performance of conventional shock absorber , two automotive mr dampers were designed and fabricated at chongqing university . an applied magnetic field increase the yield stress of mr fluids in flow annular passages , which alters the velocity profile of mr fluid in the passages and raise the pressure gradient between low cavity and high one at some given flow rates
根据磁流变阻尼器工作模式，利用磁路中的欧姆定律和动态磁路设计原理，结合汽车悬架的技术要求和结构特点，提出了基于剪切模式和流动模式共同作用（混合工作模式）的汽车磁流变阻尼器设计原理，讨论了阻尼器动态磁路设计中的若干技术问题；根据流体力学navier - stokes方程，分别利用newton流体特性和bingham流体特性，推导了基于平板模型和轴对称模型的流变学方程，得出了阻尼器阻尼力的计算方法。
