应用弹性理论导出了纸机中具有闷头的空心铸铁辊结构的过盈量上下限相对变化与车速的关系式，提出了极限车速的概念与计算方法，从而为过盈量的动态估算提供了量化依据。

For the frame foundation beam with prestressed anchor cable on the linearly elastic Winkler foundation model, elastic two-constant foundation model and isotropic elastic half-space foundation model, the thesis puts up the finite element computation model which can consider the harmonious deformation of the beam and foundation and the influences between the prestressed anchor cables. The limit design idea of the cable foundation beam has been brought out, which can ensure the safety of the beam with the limit capability of the anchor cable. The computing procedure has been given and programmed.
