| 摘 要： | 针对轧机轴承接触单元中面力不连续问题，提出子单元和微单元新概念，更新已有轧机轴承载荷边界元法面力影响系数，较精确地计算出轧机轴承载荷的三维分布。计算实例表明：计算值与实测值的误差为5％以下。

| Abstract: | Aimed at the discontinuous distribution of traction on the contact elements of mill roller bearings,a kind of new concepts about sub-element and micro-element are put forward.In the meantime,the traction influence coefficient of boundary element method of mill roller bearing load is updated;the three-dimension distribution of the load in mill roller bearing can be accurately calculated.In practice,the relative error between the calculation and measurement is less than 5%. |
