铁路货车轴承压装曲线平滑分析

Pressing-diagram Smoothing Analysis for Bearings of Rattler

为获得平滑的轴承压装曲线,采用频域设计方法,运用PI算法进行控制,分析了液压油缸质量对系统的阻尼作用,并以仿真方式给出了实验结果,从而证明该方法是正确的.

In order to get the smoothing pressing - diagram for bearings, the frequency design method and PI control method are both used in this paper. The baffler that analyses the result of the mass of hydraulic cylinder is given by simulations. By this way, the method given in this paper is proved to be correct.
