【摘要】 给出了滑动轴承存在3个自由度的试验模型。在给出轴心涡动三维运动方程的基础上,导出了求解滑动轴承18个动特性系数的计算公式。最后针对径向-推力联合动静压轴承进行了试验,得到了其动特性系数,并与理论计算结果以及二维模型试验结果进行了比较。更多还原

【Abstract】 Experimental model of three-dimension hybrid bearing oil film was made.On the basis of the three-dimension whirling equations of the journal-center,the formula for eighteen dynamic characteristic coefficients of three-dimension hybrid bearing oil film were given.The dynamic characteristic test for radial-thrust bearing was accomplished.Compared the results of two dimensions and theory,the differences between them get visible with the increase of eccentricity ratio,and the three-dimension results are close to the theory results.更多还原
