摘要
为提高轴系校中计算精度,应用有限元法开展艉轴承刚度仿真计算研究,探讨轴承内衬材料(弹性模量、泊松比)、长径比、水槽数量、橡胶层厚度对轴承刚度的影响。结果表明:减小水槽数量和橡胶层厚度,提高弹性模量,增加长径比和泊松比均有助于增加艉轴承刚度;轴承刚度受诸多因素影响,多因素间的交互作用与影响机理十分复杂,还有待深入探讨。
In order to improve the shafting alignment calculation accuracy, hmte element method was used to calculate the tube bearing stiffness and explore the stiffness was affected by the bearing lining material (Elastic modulus, Poisson's ratio) , aspect ratio, the number of the groove and thickness of rubber layer. The results showed that the bearing stiffness increase by the sink quantity and thickness of rubber layer reduced, the elastic modulus improved and the aspect ratio or Poisson's ratio increased. The bearing stiffness is affected with more factors. The mechanism of interaction and influence among the factors is very complex and has to be deeply investigated.
