| 摘 要： | 分析了以往学者们对载荷-变形规律所作的处理,提出了一种新的拟合模型。设计了结合面静态特性实验台,通过实验,研究了结合面法向刚度随载荷的变化规律。应用指数曲线对变形-载荷曲线进行了拟合,分析了拟合误差,并结合理论和实验结果,对拟合函数进行了改进,提出了新的拟合模型,减小了拟合误差,能够为工程应用提供较高精度的数据。

| Abstract: | After analyzing the approach on load-deformation of the former scholars,this paper proposes a new fitting model.Experiment is designed and the variation of normal stiffness with load is studied.The deformation-load curve is fitted with exponential curve and the fitting error is analyzed.The fitting function is improved and a new fitting model is proposed with the help of theory and experimental results.The fitting error is reduced and data with high accuracy can be obtained and used in engineering. |
