摘 要: In this article the couple stress effects on the static and dynamic characteristics of parabolic and plane inclined slider bearings in the presence of an applied magnetic field with squeeze action is analyzed theoretically. The modified magnetohydrodynamic (MHD) couple stress Reynolds equation is derived. The closed-form solution for the film pressure of parabolic and inclined plane slider bearings is obtained and used to study the MHD couple stress static and dynamic characteristics of these bearings. The results predict a higher steady load-carrying capacity, dynamic stiffness, and damping coefficient for the bearings lubricated with MHD couple stress fluid than the corresponding Newtonian case. It is observed that the parabolic-shaped slider bearings provide greater steady load-carrying capacity, dynamic stiffness, and damping coefficients compared to the plane inclined slider bearings.

在本文中,作者从理论上分析了在施加磁场并伴有挤压作用的情况下,抛物线形和平面倾斜滑块轴承的静态和动态特性所受到的耦合力的影响。他们推导出了修正的磁流体动力学(MHD)耦合力矩雷诺方程。他们获得了抛物线形和倾斜平面滑块轴承的膜压力的封闭形式解,并利用该解来研究这些轴承的MHD耦合力矩静态和动态特性。结果表明,用MHD耦合力矩流体润滑的轴承具有更高的稳态承载能力、动态刚度和阻尼系数,相比相应的牛顿流体情况要好。观察发现,抛物线形滑块轴承的稳态承载能力、动态刚度和阻尼系数要大于平面倾斜滑块轴承。
