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。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. results of two dimensions and theory, the differences between them get visible with the increase of eccentricity three-dimension results are close to the theory results.
