紧螺栓联接的非线性计算理论

A Nonlinear Theory for Designing the Tight Bolted Connections

在实验的基础上，建立了在受轴向载荷紧螺栓联接中，被联接件的受力与变形的非线性方程。导出了各项计算公式，并通过实例对传统的线性理论与非线性理论进行比较，结果表明非线性理论较为符合实际。

This paper presents the nonlinear equations, which describe the relationship between the load and the deformation of the joint elements on the basis of experiments. Several calculating formulae are derived. It shows that the nonlinear theory is more reasonable and consistent with the practice.
