The effect of the testing platform is given , including its photo and the experiment curves that have been measured . the rotor speed curve , the axis track curve and the limited speed curve are listed . finally , the work that has been finished and will be done to transform the testing platform to a product is summarized 作者给出了目前实验台所达到的效果，列出了实验台的照片和所测得的实验曲线，包括转速随时间变化曲线、轴心轨迹曲线和临界转速曲线，最后对全文进行了总结，并提出了旋转机械动态测量实验台产品化所尚需完成的工作。
It is constructed that radial impact and rubbing dynamics differential equations of the rotor system having the nonlinear rigidity on the unsteady and non - linear oil film . the bifurcation and chaos behavior of impact and rubbing fault rotor system caused by the parameters of nonlinear rigidity , rotor rotating speed , eccentric mass is analyzed , in the numerical value analysis method . the bifurcation diagrams , maximum lyapunov exponent diagrams , poincar maps , phase plane portraits , trajectories of journal center , time - history curve , amplitude spectra diagrams of the rotor motion are used ( 2 )建立了具有非线性刚度的转子系统在非稳态非线性油膜力作用下的径向碰摩动力学微分方程,并应用含高阶余项的非线性动力方程的线性化数值法研究了此类系统响应的复杂动力学行为,利用转子响应的分岔图、最大lyapunov指数曲线、 poincar截面映射、时域波形、相轨线、轴心轨迹、幅值谱等图形分析了系统响应的周期运动、拟周期运动、倍周期分岔、混沌等运动形式的转化与演变过程,重点研究了非线性刚度、转子转速、偏心质量等系统参数对碰摩故障转子系统的分岔和混沌行为的影响。
Under the dynamic loading situation , the method of hahn and reynolds boundary condition are used to calculate the journal center trail of plain journal bearing . this progress is made into computer programmer too . the progress of calculating the journal center trail of three - lobe journal is another way different from plain journal bearing 在滑动轴承的动载情况的分析中，论文运用hahn法对圆柱滑动轴承的动载轴心轨迹曲线进行了求解，创造性地结合雷诺积分边界条件的思想对半sommerfeld条件的应用进行了修正，提高了计算精度，并在此基础上进行了程序编制。
